    Later on the edges of the rolled plate are forged so that v-shaped notches are on the exterior and interior area of the seam. Then the pipe seam is being welded by an arc welder submerged under flux. In the case of high thickness pipe, multiple pass welding is done. In a Spiral SAW pipe, steel plate from the de-coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe.Welding stainless steel right - The FABRICATORA fabricator new to welding stainless steel would probably not need to invest in a different type of gas or delivery system.
