Which is better hydrogen welding or argon arc welding?
And there has a tendency to crack when water quenching. The hydrogen welding and argon arc welding is good for it, but the gas welding is not. It is required to preheat before the welding, and stress relief annealing should be performed after welding.See all results for this questionWhat kind of electrodes are used in arc welding?Alternatively, use alloyed basic coated electrodes giving welds with yield strengths matching the alloy steel. MIG/MAG (GMAW) welding or flux cored arc welding can also be used with consumables giving weld metal of appropriate strength. When welding is completed allow components to cool to 200°C before temperingSee all results for this questionWhat kind of Rod do you use to weld carbon steel?I've also used plain carbon steel rod E7018 in lower stress welds, such as welding carbon steel to 4140 or 4340.
