Hi jarcher. I understand the term: "Maximum to be welded" as the thickness, t, of the Weld Metal in the Coupon over 13.0 mm. For example, if I qualified a welder with a coupon with 25.0 mm of (t). the welder would be only qualified to weld until 25.0 mm of (t), that would be "maximum to be welded. As you can see, a welder who welds a plate with 13.0 mm of (t) probably he is not realible to weld 38.0 mm of (t), or more than that. I think so. The term would be unlimited and not " Maximum to be welded". Do you agree with me?
