ようになされている。As shown in FIG. 8, the upper welded member 1a
And a lower welded member 1b are butted against each other to form a welding joint for lateral welding having a V-shaped groove 2.
A double-sided adhesive tape 4 is adhered to one surface of the long-length front cover material 3 corresponding to the welded member side, and an aluminum tape 5 with an adhesive is adhered to the other surface. Then, the ceramic front cover material 3 is formed by the double-sided adhesive tape 4 and the adhesive-attached aluminum tape 5,
The lower surface of the member to be welded 1b is adhesively fixed along the groove 2. In this case, the front cover member 3 is adhesively fixed such that the upper portion thereof projects upward from the lower edge portion 2a of the groove 2. In addition, the standard length of the front cover material 3 is about 600 mm (width is about 30 mm), and in the case of a welded joint exceeding this length, a plurality of front cover materials 3 are used according to the groove length. They are arranged in a line along the groove and are fixed by adhesion.

を示している。When the front cover material 3 is attached to the front surface of the member 1b to be welded in this way and the horizontal posture arc welding of the groove 2 is performed, the weld metal which tends to hang down from the groove 2 is used as the front cover material 3. Is blocked by the upper end of the groove and solidifies in the groove 2.
Therefore, dripping of the weld metal is prevented, and the welding of the groove 2 of the lateral welded joint is completed by performing the welding of two layers or three layers. After that, the front cover member 3 is peeled off from the member to be welded 1b, and the welding operation is completed. Note that FIG. 8 shows the weld beads up to the second layer in the three-layer welding.

With the progress of the above, the adhesive strength of the adhesive tapes 4 and 5 was lowered by the welding heat, and the cover member 3 often dropped during welding. For this reason, it is necessary to interrupt the arc welding and re-bond and fix the surface covering material again, or to repair the weld bead joint part due to the interruption of welding, and it is not possible to reliably perform horizontal arc welding using the surface covering material. There was a problem.

Keep it. Next, when the entire supporting jig is brought close to the member to be welded, the tip of the pressing member is brought into contact with the front cover member, and the base end of the pressing member is brought into contact with the surface of the member to be welded. The magnetic force causes the compression coil spring to further move from the surface of the pressing member that has been pressed until then toward the member to be welded while moving forward together with the support shaft, and to be attracted to the surface of the member to be welded. Then fixed. Then, when the magnet is attracted to and fixed to the member to be welded, the base end portion of the member to be welded is used as a fulcrum, and the compression coil spring contact portion of the pressing member is pressed as a force point by the elastic urging force of the compression coil spring. As a result, the tip end portion of the pressing member serves as a point of action, and a pressing force for pressing the front cover material toward the member to be welded acts on the tip portion. In this way, the front cover member can be reliably pressed against the front surface of the member to be welded.

すればよい。It is preferable that the pressing force for pressing the front cover material against the member to be welded is a constant value that does not vary and satisfies a required magnitude. If the pressing member is provided with a stopper member that restricts the forward movement of the spring pressure adjusting nut, when the magnet is attracted and fixed to the surface of the front surface of the welded member, the spring pressure adjusting nut that has moved forward together with the support shaft is a stopper member. When it stops before, the spring pressure adjusting nut may be manually tightened until it comes into contact with the stopper member.
