Are they leaf springs?
Inner pass/multi pass welding on high Carbon steel isn't suppose to go over 350* and preheat is suppose to be 125-200*, at least thats how it is at BIW shipyard.
Oldpath,
Last time I tried to guess what numbers meant in a welding thread I mistook PSI for dollars so this time I'll ask flat out. What do 350* and 125-200* refer to? I don't understand the asterisk.
