P11/ T11 Pipe Tube Processing / Welding

Standard welding processes for these steel grades are:
TIG-welding Arc welding (E)
MAG-welding massive wire Submerged arc welding (SAW)
MAG- welding cored wire
Depending on the welding position and the plate thickness, maybe other filler metals have to be applied, which can be asked inquired at the manufacturer in case of need.
