Attached i included two photos from welding (material Cr Mo V steel, process TIG ). As you can see from picture there is change in color of the weld.Visualy my interpretation is that welder increaed welding speed (therefore heat input was decreased), in copper colored area he welded more faster and made weld puddles more thick.Where on left side color of the weld pool looks good(similar to base material) and paddles are in range.
My question is " if the weld puddles looks thicker and color is like copper can it be rejected, especially in welders skill test"?
Thanks in advance for any opinion.
