metal glue vs welding

Optimum is 0.004” to 0.01”. Heat resistant glue for metal is common in public transport vehicles, automotive industry and general industrial applications. That tool/toy/household item is back together and will probably last for years. When metal pieces being joined are large and have similar melting points it works well: the pieces fuse in the melt pool and two become one. Well if you fly in a plane, ride in a car or go up a tall building you may already have done so. For repair jobs in your own house you probably go with a two-part epoxy. One thing to remember is that while cyanoacrylates and epoxies have a role, in general we’re talking about methyl methacrylate adhesives. In fairness, gluing isn’t really the best word to use. But the same is true for welding. Facts. The welding process requires 5 steps: Prep metal, tack weld, stich weld, grind, and seal. For repair jobs in your own house you probably go with a two-part epoxy. It’s fast and forms an incredibly strong bond, which is why in some quarters they call it Super Glue. So let’s talk about adhesive bonding in fabrication, highlight a few applications, and discuss how it compares with welding. Chemical Metal is good. Cure time. PTI Industries offers high-tech adhesive bonding as part of a one-stop experience for all your special processes. Tel: (860) 698-9266 Metal glue is a great way to join metal to metal, or metal to other materials. ), Can provide a sealing function. ... this I suspect would be true as the glue can be applied along the seam whereas traditional methods would use spot welding. Some can be nasty, so wear gloves, face-mask etc as recommended. No grinding or sealing is needed because Plexus adhesive generates significantly less heat than welding. Glues for homeowners needing to bond metal to metal fall into three general types -- epoxy, polyurethane and cyanoacrylate products. Before we dive into the welding comparison there are a few caveats we need to mention with regard to adhesives. The adhesive compensates for differences in … The older adhesives weren’t ideal for bonding metal to metal, but newer adhesive types have proven their worth as a viable adhesive bonding option. 2 Peerless Way There’s a little bit of prep to do, (the mixing,) then you spread a thin film and push the two surfaces together. Structural adhesives excel in joining dissimilar substrates and materials with different thicknesses. It will set in 4 to 6 hours and cures between 15-20 hours.JB Weld metal glue can be your lifetime companion on the matter of metal repairing. Welding is a heat process, and that’s both it’s strength and it’s weakness. 5 Pearson Way And this epoxy cement from J-B Weld induces this best metal epoxy glue that dries with little shrinkage and running.. When you consider adhesive bonding versus welding for securing your parts, strict specifications must be met while controlling the total cost. (There are some good diagrams at “. Composite materials used in various high-end, low volume cars have long been bonded together. Having plenty of metal minimizes distortion and with little risk of cracking the resulting joint is strong and durable. Heat, humidity, vibration and just time will lead it to fail. Usually, if you want to join two metal objects together, you either weld or solder them depending on how big they are. by David Duchesne | Jul 10, 2019 | Future of Metal Fabrication, Manufacturing, Manufacturing Technology, Welding. It's a glue that bonds metal to metal or to other materials and it sets at room temperature. Will a change in joint geometry design pay off? (If you know a way to weld carbon fiber there are a few companies waiting to hear from you!) Consult with your special processes provider for help with the right adhesive technology. These are extremely powerful industrial-grade glues and they need careful handling. Consider how your overall manufacturing time can be reduced with adhesive bonding by analyzing your processes. Adhesive bonding is better. In addition to bonding honeycomb structures, other aerospace applications include bonding fasteners to metal hard points. New applications are being developed and tested daily. If a change in your joining process improves efficiency and quality, and reduces overall manufacturing time, it’s worth the effort to switch from welding to adhesive bonding. Actually, using a metal epoxy is the best way to bond metal to metal without welding. Reports from the agricultural industry show workers are repairing metal fences using structural adhesives instead of welding. These adhesives provide dimensional stability – the ability for a part to hold its design dimension – that improves product longevity. Fortunately, there are special adhesive products on the market made for gluing metal. We have two popular solutions to broken metal pieces. Soldering is one method that is widely used to accomplish this. Check the environmental conditions. Here architects like adhesives because they eliminate stress-risers and can also improve the overall appearance. (Some people just call them acrylic adhesives.). Gluing metal to metal vs. welding Most enthusiasts don't have welding experience or the required welder and related tools. And then there’s all the prep and clean-up, which takes time and adds cost. Epoxies, urethanes, and acrylics are adhesive alternatives to fasteners and welding. Their glue comes in basic packaging with the claim “World’s Strongest Bond” printed at the top. Points that appeal to designers in particular are: However, there are also some downsides to using adhesives, most notably: If you’ve never considered adhesive bonding in your next fabrication project perhaps this blog post has opened your eyes to the possibilities. For a project, I am making a stainless steel cabinet and I have to weld two sheets of rather thin (5mm) sheet metal together. This steel reinforced epoxy is ideal for sealing welded seams, filling metal cracks, and mounting metal components. ), Not easy to weld dissimilar metals. The type of adhesive needed depends on the application, as some adhesives work better on certain substrates or have certain chemical advantages. Can you switch over to adhesive bonding with only procedural and part-flow changes? Welding / Brazing / Soldering (Thermal Bonding) vs. Adhesive Bonding Thermal attachments such as welding are familiar and accepted in the marketplace because the consumable materials are inexpensive and thermal bonding is usually faster since there is no cure time. So how would you feel about gluing things together? Modern structural adhesives join products with strength comparable to that of welding and at the same time open up more design possibilities. That’s changing, as described in an Assembly Magazine article. From time to time, you may need to fasten two or more pieces of metal together without bolting, soldering or welding them. Likewise, sealing and gasketing materials have been bonded onto metal, often with a pressure sensitive adhesive (PSA.) Where they haven’t been used until recently is for metal-to-metal bonding. What it isn’t though is durable. Formerly known as the MSDS, this describes the hazards associated with your chosen adhesive. Adhesive is the new kid on the block for many metal fabricators. Adhesive bonding overcomes some of these issues. Here’s a comparison of the advantages of traditional welding to adhesive bonding’s newest technology: Making the change from welding to adhesive bonding requires a comprehensive view of your bonding needs. While soldering is useful for many purposes, it has limitations. adhesive bonding in body-in-white assembly, Consumption of Aluminum Extrusion Just Keeps On Rising, 5 MANUFACTURING TECHNOLOGY TRENDS FOR FUTURE SUCCESS, Understanding Temper and Tolerance in Extruded Aluminum, Design for compression. There’s a little bit of prep to do, (the mixing,) then you spread a thin film and push the two surfaces toge… (High temperatures tend to burn through and cause distortion. Switching over to a new joining process requires addressing many issues, including safety concerns, excessive down time, structural integrity, and structural degradation, as well as your overall manufacturing process. The older adhesives weren’t ideal for bonding metal to metal, but newer adhesive types have proven their worth as a viable adhesive bonding option. A proper weld is as strong as the base material, sometimes stronger. More likely, it was an industrial-grade structural adhesive. (Not all adhesives can be used this way: look for paste adhesives if this function is needed. These could be joined with fasteners but in many cases adhesive bonding is preferred. When looking for the best glue for metal, J-B Weld brand comes up quite often. Your email address will not be published. Needs “fit-up” to position and fixture the pieces being welded, Not easy to weld thin materials. Your email address will not be published. The reason is simple: pot metal is quite similar to aluminum, and thus the approach you use to weld aluminum is the same you’ll use to TIG-weld pot metal. Instead, try to design joints where the adhesive is in compression. Adhesives don’t fare well in peel or tension applications. Read the article yourself for the details, but the bottom line is, VW believe bonding offers advantages over welding in some specific applications. Fax: (860) 698-6794, Building #2 (Wasn’t that a song?) This describes how VW have adopted adhesive bonding in body-in-white assembly of several Audi models. Enfield, CT 06082 Everyone who works with metal, from metal workers and mechanics to jewelers and hobbyists, knows gluing metal … Several paragraphs ago we mentioned that cars, aircraft and skyscrapers all incorporate adhesive bonding. (CompositesWorld defines structural adhesives as those that can take up to 1,000 psi in a lap-shear test. Metal glue can also be used for supporting fasteners: threadlocking and thread sealing are common applications where a metal glue makes sure the fastener does not loosen over time. Both processes involve the application of heat, however. Also, in the context of metal fabrication, a few years ago adhesive producer Henkel built a trailer where the panels were joined with adhesives rather than conventional fasteners. For example, the lack of protruding fastener heads gives both welded parts and glued metal parts a … J-B Weld only adheres to the surface, so the bond strength is actually only 1800 PSI. Welding or installing mechanical fasteners generally is much more time consuming compared to using an adhesive. Needs precise application. New metallic glue could replace welding and soldering. At the same time, structural adhesive technology has been used in body shops for nearly 20 years. ), Epoxies, cyanoacrylates and even polyurethanes can all form strong bonds, but today the strongest bonds are formed with a class of adhesives called methyl methacrylates or MMAs. Metal-Bonding Adhesives vs Welding. Here, high temperature means over 150°F, and some adhesives won’t go that high. In fabrication the main way we create permanent joins is by welding. JB Weld uses metal, most boat stores sell a cotton filler called flox. Surface preparation needed. Takes 4-6 hours to grab the surface with a gray color finish. Your goal of cost savings and production efficiency requires choosing the most effective material for your adhesive bonding needs. 3M™ Scotch-Weld™ Metal Bonder Acrylic Adhesive DP8407NS is a gray structural adhesive with high overlap shear and peel strength with good impact resistance and durability. Give the epoxy some time to cure and voila! Can reduce the transmission of vibration. Tradesmen often use brazing or welding instead to … Not easy to weld high thermal conductivity metals. It probably wasn’t a hardware store two-part that was holding them together though. Soldering "glues" the pieces of metal together by melting a softer metal to act as an adhesive. If you’re putting your mother-in-law’s best vase back together a cyanoacrylate is probably what you reach for. That's why scientists at Boston's Northeastern University created MesoGlue. There are many ways to bond metal together including welding, rivets, mechanical fasteners & gluing. This adhesive was designed to bond permanently to bare metals with minimal surface preparation, but also bonds well to wide variety of other materials, including most plastics. (Hopefully you’re far away when that happens!). Gluing brings to mind assembling cardboard cartons and elementary school craft projects. In this article we will look at the best way to bond metal without welding, rivets or mechanical fasteners. It offers a perfect two-part epoxy weld system that requires mixing before application. So epoxies are good, but would you trust your life to them? Another limitation is in high temperature and high humidity applications. So, you might be a handyman or a mechanic or just another person with a broken metal … Depending on the specific adhesive, this can range from minutes to hours and adds a delay into the manufacturing sequence. What it isn’t though is durable. It’s very good with dissimilar materials and works well with thin sheet, (subject to good joint design!) And maybe the epoxy would result in a more rustproof seam. Enfield, CT 06082 Go thicker and strength drops, unless you’re using an adhesive with filler that’s engineered for larger gaps. Fax: (860) 265-3558, Precision Cleaning – Laser Components and Heat Exchangers, Additive Manufactured Component Processing, https://ptiindustries.com/wp-content/uploads/2016/10/Bond-51-2-crop-e1487969524762.jpg, https://ptiindustries.com/wp-content/uploads/2017/02/Logo-300x117-300x117-1-300x117.png. Thin materials, dissimilar materials, aluminum, even stainless can present challenges. For most everyday situations and simple DIY projects, a liquid adhesive or glue for metal is the best solution. A new type of metallic glue can bond two pieces of metal together at room temperature. This can damage the items (in the case of electronics), or even cause explosions (in the case of things like gas pipes). These products claim to make strong metal-to-metal bonds if users follow instructions. While steel frames will be bolted and welded for the foreseeable future, adhesives are making inroads into construction. Adhesive vs welding and mechanical fixing – Who is choosing structural adhesive? Permatex Steel Weld™ epoxy is a multi-metal epoxy adhesive that eliminates the need for welding or brazing and is resistant to water and solvents. J-B Weld epoxy adhesive is the most reliable choice when you need to apply stronger adhesive for hard plastic or metallic surfaces. One of the biggest applications is in bonding exterior cladding to the frame. J-B Weld has a tensile strength of 3900 PSI; which is 65% the strength of filler metal. Adhesives avoid the need for fasteners, which means no drilled holes, (themselves stress-raisers,) and no nuts and bolts, which add weight. We can either weld those or we can glue those. Adhesive is the new kid on the block for many metal fabricators. Tel: (860) 265-7860 Wood is very amenable to gluing, with the added benefit that it doesn’t split, but you will also find adhesives in modern glass and metal buildings. If you’re putting your mother-in-law’s best vase back together a cyanoacrylate is probably what you reach for. (Hopefully you’re far away when that happens!) The first step was to cut out the rust. Of course, welding also needs good hand-eye coordination, so is this an argument against adhesive bonding? Required fields are marked *, FAA REPAIR STATION #OPIR361L, NADCAP & EASA CERTIFIED, Building #1 Read about it and watch a video at “Work Truck and Trailer.”. Some industrial versions will take up to 4,000 psi before failing. Can create a “liquid shim.” This takes up gaps between mating pieces and so allows wider tolerances. In today's video I will be showing you how to glue a broken piece of metal back together using J-B Weld cold weld steel reinforced epoxy. Can shape, tapped, filed, sanded and drilled after curing. Welding is a very common technique for metal-to-metal assembly operations, and in some ways using adhesive for metal is very similar. Weight minimization is paramount in aerospace, which is why they use a variety of different composite materials. PTI Continues to Offer UTAS Special Processes for Civil and Military Aerospace... PTI Industries Cleared to Launch Precision Cleaning for SpaceX, No curing time needed in production process, Flexibility with attachment location, including large objects with small welding areas, No shelf life or monitoring of storage time necessary, No distorting or discoloring of thin metals, Won’t destroy galvanized coatings or cause corrosion, Minor joint design changes to accommodate surface contact, Assembly of different masses and dimensions, Joins irregular shaped surfaces with minimal alteration to part dimensions, Gives increased fatigue strength by distributing stress across bonded area. J-B Weld, known as "The Original Cold Weld," was developed as an alternative to traditional torch welding. Welding in patch panels with a flux-core welder without a gas envelope is an exercise in burn-through and swearing—so glue it was. It's designed to be extremely effective in even the harshest environments. Epoxy Bonding vs. Welding Hello, r/welding . The answer is “everyone”. When you start the actual welding, ensure you work slowly using low-temperature settings. Now let’s take a deeper dive. With Plexus adhesive, the process is reduced to 4 steps: prep metal, dispense adhesive, clamp, unclamp. Consider the bondline thickness required. It’s fast and forms an incredibly strong bond, which is why in some quarters they call it Super Glue. Bond Metal With Glue. There are two general ways to join metal components together — soldering and welding. Adhesive bonding is how cars, aircraft and skyscrapers are put together, (or parts of them anyway.) Because it's a two-component (or 2k) epoxy system, it uses reactive chemistry to create the strongest bond possible. Structural adhesives are those which work under loads. We’d love to talk. Welding has it’s drawbacks though, some of which we’ve discussed here. If you're welding steel, which is what most bikes are made of, then it will be as strong as steel. Check the Safety Data Sheet (SDS.) (A consequence of different melting points.). Metal-… This quick setting steel reinforced epoxy comes as a two-component set and is the faster curing version of the original cold weld two-part epoxy. If you’d like to learn more about what they could do for you, give us a call or click the button below. Here’s a comparison of the advantages of traditional welding to adhesive bonding’s newest technology: Welding Advantages It doesn’t cause distortion or cracking, it can be applied in hard-to-reach locations and it doesn’t damage galvanized surfaces.
