  Those were specified because the bolts must be ringed with weld to provide a seal and they are believed to be " weldable"   Once the structural joints are welded the A bolts simply fill the hole At this point threaded studs will not work The plan is to weld the clips and fill the holes with A bolts which will be sealed Perfect welding needs so much more than just a welding machine, a welding torch and a few welding accessories. For the past 60 years, EWM AG has been engaged not only in the production of welding machines and the required accessories, but also to a greater extent in researching and developing innovative welding processes and components.Done that lots of time, heres a trick.. I have welded nuts to bolts many times but with alumnium its tricky heres why. Biggest probelm with steel fasteners in alumnium heads is the metal corrode and lock the materials together, the trick I have found to remove them is this, drill a hole in the broken stud, next weld the hole up. try to get the wire all the way to the bottom of the fasterner ...Anchor bolts and tie rods up to 4 in. in diameter using materials such as ASTM F1554 grades 55 and 105, A588, A325, A449, A490, A354, and A193. All made of domestic steel with full material certifications available. Structural Bolts Products include a full line of heavy hex structural bolts ASTM A325-1 and A325-3, and ASTM A490-1 andThe bolt would extend through holes in each piece of steel Due to accessibility we prefer to weld a nut to only one side of each piece of structural steel With the bolt in tension the nut would bear directly against the steel With the bolt in compression the nut would transfer forces through a weld all around to the structural member Perfect welding needs so much more than just a welding machine a welding torch and a few welding accessories For the past 60 years EWM AG has been engaged not only in the production of welding machines and the required accessories but also to a greater extent in researching and developing innovative welding processes and components The M8 Stainless Steel Weld Nut and other sizes are used for different types of applications The nuts are welded with projection welding most of the times because of the thicker welding finish by the projection welding Welding with EWM means: State-of-the-art welding technology, optimal usability and first-class results. EWM welding machines offer a technological advantage in all welding procedures. This is characterised by a high level of efficiency, conservation of resources, and sustainability when welding.
