Welders weld the spiral seam in site. Tubular were fixed horizontal.

I do have another question. The spiral is usually welded by the manufacturer using mechanized or automatic welding machines. How is it that your welders are welding the spiral on-site? I can understand the welders welding the girth joint or welding a branch, but under what circumstance are they be welding the spiral?
