First, a plurality of columns 1 are built, and a beam 2 is passed over the columns 1 with bolts not shown. After temporarily tightening and adjusting the verticality, horizontality, etc., fully tighten. Further, a deck plate 3 is laid on the upper surface of the beam 2 to temporarily finish the floor surface. And when building the upper floor on this,
The next pillar 1 'is joined to the existing pillar 1, and the above procedure is repeated. FIG. 5 is an explanatory view showing how to join the columns by welding.

However, it depends on the skill of the welding operator, and in particular, horizontal welding in the field leads to poor quality due to poor working environment such as on a scaffold.

Therefore, it is difficult for the welding operator to adjust the welding condition, and the manual method requires one welding operation per worker. Since the welding is performed by the torch, the efficiency is low, and the arc time ratio, that is, the ratio of the true welding time to the total working time is low due to fatigue.
