Nothing special but does a good job in most cases. J-B WELD ORIGINAL: The Original Cold Weld two-part epoxy system that was designed as an alternative to torch welding. JB weld is easier. either way, fasteners or some variety of press fit would be better, and the press fit not so much if it's going to be exposed to any sort of temperature changes (different coefficients of thermal expansion, gets cold out, and the aluminum will fall right out of the stainless). The harder the solder the stronger, too. And 3M 2216 A/B is better than JB Weld, but it is $$$$$ Take a small piece of copper tubing 2"-3" long and squish it until it fits inside the half round area. That is, roughly 30 MPa for JBWeld, versus about 300 MPa for aluminum alloy. JB weld is epoxy; it just has a filler that is hard, and made for cheap fixing of castings. JB Weld allows you to use the finished surfaces in conditions up to 550 degrees F, while Loctite Epoxy weld is limited to an upper temperature of 350 degrees F. Conclusion Overall, for heavy duty applications, JB Weld is the clear winner, giving you a much stronger bond that can operate in harsher conditions than bonds formed with Loctite ⦠JB Weld is a consumer quality epoxy. For building gussets the flox can help. There may be other epoxies on the market that are potentially stronger - but JB-Weld has been around since the 1960's and has only been improved. I have never used the Belzona brand but I have used Devcon Liquid Steel and I can attest it is an incredible product. JB will be stronger than a bad solder joint so if you cant make a solder joint for nothing, JB will be good. Just have to have more heat to get the job done. Motorcycle engine tuners actually use JB weld on the internal cylinder head ports in order to increase port radius and speed up air flow, it never ⦠Solder is stronger. It seems to do all of the things it says on the box. Correct. jb weld =/= real weld. JB weld is easier. Re: Stronger than JB Weld or precision machinist I the part is Aluminum, you could try filling the hole with Aluminum brazing rod, then re-do the hole. If you need to do something requiring greater strength you might look to metal welding. JB Weld uses metal, most boat stores sell a cotton filler called flox. Cures much harder than JB ⦠Mixing in fibers can make epoxy stronger in certain situations. This question has already been satisfactorily answered but an important difference between an epoxy glue and super glue is the fragility of the glue joint. In my link theres a video that shows it in action. There are many industrial quality epoxy adhesives that are far superior to the JB Weld class of products. J-B Weld Original provides strong, lasting repairs to multiple surfaces and creates a bond stronger than steel. A super glue joint can be broken by an impact. JB will be stronger than a bad solder joint so if you cant make a solder joint for nothing, JB will be good. JB weld is epoxy; it just has a filler that is hard, and made for cheap fixing of castings. Solder is stronger. JB weld is stronger than either acuglas resin or gel , JB weld is similar in strength to industrial strength 3M steel epoxy and is far superior to any of brownells acuglass. ROUGH UP ALL surfaces where glue goes, then apply adhesive. From this simple calculation, it kind of looks like, aluminum alloy has greater tensile strength than JBWeld (r), by a factor of about 10.
