As manufacturers strive for lower costs and greater efficiencies, they tend to substitute high-strength materials for standard materials. One such high-strength material is ASTM A514/514M-05. Although it is not difficult to weld, joining it successfully requires paying close attention to the preheat temperature, interpass temperature, and filler metal.

Q: I am building a 400-gallon paint tank and I'm having trouble with leaks when using gas metal arc welding (GMAW). I'm using a welding machine running on 440. My best results come when running hot 19.5 on the heat and about 21/2 on wire speed. I am using a trimix gas and 0.035-inch 308 wire. The...
