Bronze cladding for lower friction.WPS/PQR needed?
(OP)
Hi, we have a valve for which all the pressure bearing weldments have their WPS/WPQR and qualified welders. But we have a bronze cladding just to lower the friciton. Is not a pressure bearing, nor under stress. Do I need a the same process as for the pressure bearing weldments?
Best regards

Likewise your welders require qualification to QW-382 Hard-Facing Weld Metal Overlay (Wear Resistant). No qualification is unlimited in scope.
p.s., there is no such thing as a non-load carrying weld.
