How to Weld for the ERW Steel Pipe in Winter
To ensure that the erw steel pipe in the winter welding perfect follow the following steps:
First, increase the welding current welding, slow down the welding speed, the appropriate increase in the cross-sectional area and length of the weld, if necessary, preheat.
Second, not outside the groove on the base metal to start arc, arc extinction to be filled when the pit.
Third, as far as possible not in low temperature conditions for bending, correction and assembly weldments.
Fourth, preheating before welding, welding process to strictly maintain the interlayer temperature should not be lower than the preheating temperature.
Fifth, the use of low hydrogen or ultra-low hydrogen welding materials.
Six, the entire weld should be finished as far as possible to avoid interruption.
