Forgetting to cut out and feather tacks would be a mistake cannot be forgive. This would lead to the bad quality for the welded steel pipe like the ERW steel pipe. Then how to avoid this trouble’s happening?

 

The welder cuts out and feather the tack in order to make sure the consistency of the final weld. For those factories, that a fitter would be prepared and then others will to do the rest welding work. At this time, it is important that the welder knows just what is in the weld. If we keep tacks left in the joint which was consumed by the weld. Once there is defect in the tack or if the fitter used the wrong filler metal to tack the joint, there is a risk for defects in the weld. Cutting out and feathering the tacks helps eliminate this potential problem.
