This is the angle frame material (
Electric arc welding A is applied at appropriate intervals along the edge of each angle frame member (L-shaped steel) 2 to adhesively fix the L-shaped steel 2 and the external wall steel plate 3 that is attached to cover the outer surface of the steel. This is what I did. However, in this case,
As shown in Fig. 7, during cooling after welding, an inwardly depressed recess B is generated on the external surface of the outer wall steel plate 3 at the welded part as a trace of distortion and oxidation due to welding, and this is a trace as shown in Fig. 5. A large number of them remain on the external surface of the exterior wall steel plate 3.

After welding 2 and the exterior wall steel plate 3, many recesses B and D (7) welding marks remain on the external surface of the exterior wall steel plate 3 and the appearance is not good. The depth dimension G of the recess (7th.
After polishing and smoothing with a grinder until it reached the level shown in Figure 9), it had to be painted. Further, when the depth dimension G of the recessed portion is large, it is necessary to apply putty (a mixture of resin and inorganic material) or the like to that portion, harden it, polish it to make it smooth, and then paint it.

If the area is deep, there is no need to apply putty or the like to the area, harden it, and then polish it.
５）前記ｌ）と４）の関係で、従来に比し制御盤の函体
