Even you have been worked in steel pipe’s industry for a long time, you cannot ignore the detailed difference even for welded steel pipe like ERW steel pipe or other types of steel tube.
It would be nice if we hire experienced welder for producing steel tubes. However, the general misunderstanding is that they have work experience, but they may fix them. For example, welders with stick experience may not understanding how to properly prepare a joint for wire processes common in pipe fabrication applications. Under this situation, there would be a series trouble: focusing too much heat into the edges of the weld, a lack of penetration and insufficient reinforcement on the inside of the pipe. How to solve this question? And finally provide customers with high quality steel pipe? As far as editor in Primesteeltube consider, we will adopt experts to the specifics of each application and make sure they understand different weld preparation and operational techniques before they go to work.
