Hi there Ive only done oxy-acet gas welding on old Triumph cars but now need to weld a chassis outrigger on 1989 volvo 340 which looks like high tensile steel . I read on google that gas welding can weaken "modern" steels. Would this apply to 1989 metal. Surely Mig or spot weld local temperatures must be higher than gas (oxy-acetylene)temperatures . I am confused!
thanks, Steve
