| Advantage of combining two processes: Suppose u have two wps as below 1: WPS with GTAW with 13mm base plate thickness (Base metal Qualification range is 26mm max) 2:WPS with SMAW with 20mm base plate thickness (Base metal Qualification range is 40mm max) If u combined these two WPS, the advantage you can get is u can weld GTAW process double the max thickness between two process ie (2 x 20mm = 40mm) not upto 26mm only. You can use more than one WPS in one single joint, just to increase base metal thickness qualification range one can combine two process as per QW-200.4(b). You can create many WPS from one single PQR as needed. Hope this is clear for you.. Mhaskar Aly -------Original Message------- Dear experts....Can anyone provide some Section IX interpretations for clause no.QW-200.4 ?................Can anybody explain this clause better ?...........It clearly states that multiple wps of different processes can be combined together and we can make a single wps combining that processes...........and from one pqr combining different processes ,individual wps can be prepared for each process..............the root deposites clause of min 13 mm is an ALTERNATE requirement....is it really applicable in which situation ?............... --To post to this group, send email to materials-welding@googlegroups.com To unsubscribe from this group, send email to materials-welding+unsubscribe@googlegroups.com For more options, visit this group's bolg at http://materials-welding.blogspot.com/ The views expressed/exchnaged in this group are members personel views and meant for educational purposes only, Users must take their own decisions w.r.t. applicable code/standard/contract documents. | ||
