How To Keep Stainless Steel From Warping During Welding. When butt welding chamfer both sides of the join but keep the included angle less than 60 and make the gap between the sheets as. I tacked the peices together and using a ton of clamps welded an inch here then an inch over there.
It could also help you weld the entire seam continuously. Using clamps strongbacks and other methods of holding parts in place can keep the metal from moving during the welding process and holding it in the proper position as the metal cools and stresses are acting on the material. When you remove the clamps the metal may still distort to a certain extent.
During stress relieving some minor relative movements will take place.
So as to reduce the thermal influence of the parts when welding stainless steel parts try to use gas protection welding as much as you can. Minimize the amount of heat put into the weld. Keeping the heat on using some rose buds and a few flunkies. Another alternative is to surround the area youre welding with an Anti-Heat Compound that will block the heat from spreading to the rest of the panel and potentially reduce warping in the panel.
