The contact angle of the slag peeling jigs 54 to 56 with respect to the welding bead 3 is set in the range of approximately 30 to 70 degrees so that the slag 4 is not made coarse particles but fine particles or medium particles (1c).
This is a necessary condition for efficient peeling by increasing the volume (less than m 3 )). However, since the slag peeling device 57 is provided on the elevating member 45 via the mounting bracket 50 so that the angle can be adjusted, It is possible to freely adjust the value within the above range and set the optimum value according to the condition of the welded portion.

In particular, as described above, a small amount of air 36 is sent to the upper air supply pipe 37 and a large amount of air 36 is sent to the lower air supply pipe 38, or the upper air supply pipe is supplied. While sending low-pressure air 36 to the pipe 37, sending high-pressure air 36 to the lower air supply pipe 37,
Since an unbalanced state is generated in the air 36 inside the slag suction mouthpieces 21 to 23 by causing a difference in the flow rate or pressure of the supplied air, the suction device main body 24 sucks the slag. Since the swirl flow 39 is forcibly generated inside the mouthpieces 21 to 23, the swirl flow 39 blows up or lifts up the slag 4 finely broken down, so that the slag 4 is efficiently supplied. Therefore, it becomes possible to suck the welding bead 3 without remaining on the surface thereof.
