Re: [MW:13102] QW-200.4

No need to combine two WPS if you don't want benefit thickness of BM, you can use more one WPS in a single joint,if your WPS is qualified for BM thickness..   Mhaskar Aly         -------Original Message-------   From: sevak hiren Date: 29/11/2011 11:27:06 To: materials-welding@googlegroups.com Subject: Re: [MW:13084] QW-200.4   Dear Sir,   Thanks for reply, but apart from your expaination, please let me know can we combine two existing WPS of different processes (Say GTAW & SMAW) of less than 13 mm thk in a single production joint as per QW-200.1 (f) ?
