is it a good idea to cool your weld immediately?? my thoughts would be it would make the weld area very brittle and then would require annealing?? its only wat i have read and been told, but then others say to quench the weld with cold air/wetrag, i thought it would also shrink the welded area more as the process of heat shrinking is the heat the metal and cool it very quickly, altho when shrinking there is no need to get it as hot as welding??
can some 1 else pls verify this as i also use a tig to weld in my panels and am confused with conflicting theories and procedures.
cheers, krem
