Conical mast with a longitudinal laser welded seam

摘要

The method comprises continuously welding a longitudinal seam of a conically bound tubular mast blank (2) in conduit by a laser, where the column (5) of the mast blank is horizontally held in the conduit. The mast blank is subjected in the conduit for closing the column by activating means. The mast blank is subjected for closing the column on both sides adjoining to the column and in an area of the blank opposite to the column on other side. The position of the activating means is adapted in the conduit driven on the conical mast form. The mast is subjected to galvanizing.
