Re: [MW:17766] welding position

There are 2 issues connected with this.

 

1. Applicability of the WPS

2. Range of Welder Qualification.

 

1. WPS qualified for 1G position can be used for 2G position also. QW 405.1 as per QW256 deals only with WPS/PQR qualification.

2. Regarding Welder qualification, you need to refer QW356 & QW405.1 & subsequent QW461.9.  If the welder is not qualified to 2G then you need to update welder qualification to 2G also.

 

Thanks & Regards
