Welded API5L X42 Gas Line Pipe 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 inquired at the manufacturer in case of need.

These steels can be welded within all thickness ranges according to the afore mentioned welding processes considering the general rules of technology by hand and automatically welding. The mentioned filler metals apply for highest demands. The details in brackets are for lower demands. Burning, preheating, welding and stress relieving annealing should occur under consideration of Stahl-Eisen-Material  bulletin 088.  Specifications and standards concerning stress relieving anneal have to be observed.
