Abstract

PURPOSE: To restrict deformation strain and obtain captioned structure of improved precision, by providing open and closed grooves in the four sides of partition boards with auxiliary plates and outer circumference constituent members, and simultaneously welding the open grooves and then opening and welding the closed grooves simultaneously.
CONSTITUTION: Welding grooves 8, 8' are formed in four sides of adjoining partition boards 6, 6 by using auxiliary plates 7, 7', and notches 9 in outer circumference constituent members 1, 2 are fitted with grooves 8 to form open grooves 8 while constituent members 3, 4 are combined with grooves 8' to form closed grooves 8'. The grooves 8 at four sides penetrating through the notches 9 are simultaneously welded by CES welding in the direction of arrow I to join the constituent members 1, 2. Then, the assembly is rotated 90°, and the closed grooves 8' are pierced and opened through, and welded simultaneously II in the direction of arrow in the same method. Thus, restricting generation of deformation strain, a pillar 5 for building or the like of advanced precision may be obtained.
