QW-405.2 welding positions - ASME IX 2019

 In ASME IX 2019 deleted supplementary essential variables “QW-405.2 welding positions” which given SMAW, FCAW, GMAW, PAW.

See SUMMARY OF CHANGES in this code book.

A qualification in any position qualifies the procedure for all positions
Also see QW-203.

A qualified in pipe also qualify for plate and vice versa. You may combine these WPSs in new procedure, also see QW-200.4
