In my company, we test welders on production weld too but this is considered to be a very risky practice because failure of welder qualification will result in cut out of joint. Originally a welder should be tested on test coupon meant for qualification but what we do in our company is that we test whose welders directly in production who have a strong track record and we are confident enough about them and other welders we test on test coupons. Some times it happens that welders employed by a company working on one project are when shifted to other project they are tested directly in production to carry out client documentation procedures and new welders are tested on test coupons.

Dear experts
Good day.in Asme sec IX for welder qualification-
in my previous company I have seen that they use production weld followed by Rt to qualify a welder, but now in my new company sometimes they are using production weld and sometimes by a welder qualification coupon.
So please tell me whether we can do either way or which is best way or in which condition we should follow any of the 2 ways.
And secondly for renewal of welder qual for 6G position.
Can we do a test coupon of 1G position and if Rt and other nde passes can he weld 6G position again or he must do a 6G test coupon to renew a 6G Welder qualification.
Thanks and regards.
