Everyone who works with metal, from metal workers and mechanics to jewelers and hobbyists, knows gluing metal … And maybe the epoxy would result in a more rustproof seam. Give the epoxy some time to cure and voila! ), Not easy to weld dissimilar metals. 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. If you’re putting your mother-in-law’s best vase back together a cyanoacrylate is probably what you reach for. Actually, using a metal epoxy is the best way to bond metal to metal without welding. JB Weld uses metal, most boat stores sell a cotton filler called flox. Metal-… Not easy to weld high thermal conductivity metals. In this article we will look at the best way to bond metal without welding, rivets or mechanical fasteners. Heat, humidity, vibration and just time will lead it to fail. Both processes involve the application of heat, however. The welding process requires 5 steps: Prep metal, tack weld, stich weld, grind, and seal. Facts. If you’re putting your mother-in-law’s best vase back together a cyanoacrylate is probably what you reach for. Bond Metal With Glue. Welding has it’s drawbacks though, some of which we’ve discussed here. J-B Weld only adheres to the surface, so the bond strength is actually only 1800 PSI. Their glue comes in basic packaging with the claim “World’s Strongest Bond” printed at the top. It’s very good with dissimilar materials and works well with thin sheet, (subject to good joint design!) 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. Gluing metal to metal vs. welding Modern structural adhesives join products with strength comparable to that of welding and at the same time open up more design possibilities. And then there’s all the prep and clean-up, which takes time and adds cost. Adhesive bonding overcomes some of these issues. (Wasn’t that a song?) Chemical Metal is good. Adhesive is the new kid on the block for many metal fabricators. When looking for the best glue for metal, J-B Weld brand comes up quite often. For repair jobs in your own house you probably go with a two-part epoxy. So how would you feel about gluing things together? 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. Reports from the agricultural industry show workers are repairing metal fences using structural adhesives instead of welding. Formerly known as the MSDS, this describes the hazards associated with your chosen adhesive. 2 Peerless Way Usually, if you want to join two metal objects together, you either weld or solder them depending on how big they are. That’s changing, as described in an Assembly Magazine article. Here, high temperature means over 150°F, and some adhesives won’t go that high. Most enthusiasts don't have welding experience or the required welder and related tools. by David Duchesne | Jul 10, 2019 | Future of Metal Fabrication, Manufacturing, Manufacturing Technology, Welding. 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. We have two popular solutions to broken metal pieces. But the same is true for welding. Tel: (860) 698-9266 These could be joined with fasteners but in many cases adhesive bonding is preferred. For most everyday situations and simple DIY projects, a liquid adhesive or glue for metal is the best solution. Structural adhesives are those which work under loads. Metal-Bonding Adhesives vs Welding. 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. Weight minimization is paramount in aerospace, which is why they use a variety of different composite materials. Here’s a comparison of the advantages of traditional welding to adhesive bonding’s newest technology: Welding Advantages In addition to bonding honeycomb structures, other aerospace applications include bonding fasteners to metal hard points. ), Can provide a sealing function. It's a glue that bonds metal to metal or to other materials and it sets at room temperature. What it isn’t though is durable. While steel frames will be bolted and welded for the foreseeable future, adhesives are making inroads into construction. Some industrial versions will take up to 4,000 psi before failing. PTI Industries offers high-tech adhesive bonding as part of a one-stop experience for all your special processes. When you consider adhesive bonding versus welding for securing your parts, strict specifications must be met while controlling the total cost. This can damage the items (in the case of electronics), or even cause explosions (in the case of things like gas pipes). A proper weld is as strong as the base material, sometimes stronger. ... this I suspect would be true as the glue can be applied along the seam whereas traditional methods would use spot welding. Enfield, CT 06082 That tool/toy/household item is back together and will probably last for years. Required fields are marked *, FAA REPAIR STATION #OPIR361L, NADCAP & EASA CERTIFIED, Building #1 Welding is a very common technique for metal-to-metal assembly operations, and in some ways using adhesive for metal is very similar. New applications are being developed and tested daily. Composite materials used in various high-end, low volume cars have long been bonded together. Surface preparation needed. Adhesive bonding is how cars, aircraft and skyscrapers are put together, (or parts of them anyway.) Having plenty of metal minimizes distortion and with little risk of cracking the resulting joint is strong and durable. While soldering is useful for many purposes, it has limitations. For a project, I am making a stainless steel cabinet and I have to weld two sheets of rather thin (5mm) sheet metal together. 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. Check the Safety Data Sheet (SDS.) (If you know a way to weld carbon fiber there are a few companies waiting to hear from you!) Read about it and watch a video at “Work Truck and Trailer.”. Consider how your overall manufacturing time can be reduced with adhesive bonding by analyzing your processes. Tradesmen often use brazing or welding instead to … (Hopefully you’re far away when that happens!). ), 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. J-B Weld, known as "The Original Cold Weld," was developed as an alternative to traditional torch welding. 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. (A consequence of different melting points.). 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. Epoxies, urethanes, and acrylics are adhesive alternatives to fasteners and welding. Your email address will not be published. It probably wasn’t a hardware store two-part that was holding them together though. (CompositesWorld defines structural adhesives as those that can take up to 1,000 psi in a lap-shear test. J-B Weld epoxy adhesive is the most reliable choice when you need to apply stronger adhesive for hard plastic or metallic surfaces. Can you switch over to adhesive bonding with only procedural and part-flow changes? Now let’s take a deeper dive. 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. That's why scientists at Boston's Northeastern University created MesoGlue.
