I would like to ask all experts, is there a requirement that the distance between two welds should not be less than 100mm when welding pipes? What are the range requirements for welding current during argon arc welding? Thanks

some. Weld spacing. I don’t know about the latter one.

If DN is greater than 50, the weld spacing should not be less than 100 or 150, and if it is less than 50, it should not be less than 50.

The specification requires that the distance between two welds should not be less than one nominal diameter. The spacing between welds with a nominal diameter less than 50 should not be less than 50. The spacing between welds with a nominal diameter greater than or equal to 50 should not be less than 100.

SH-3012 But it means that if DN>100, the nominal diameter is one time, and if it is less than 100, leave 100mm.
