。As shown in FIG. 11, this foil trim ring 1 is made by welding the abutting portions 9 of annularly formed metal plates 8 to form an annular body 10, which is then press-formed. If welding is carried out from the end 9a to the opposite end 9b of 9, the heat during welding will concentrate on the ends 9a and 9b, which will melt and easily cause a burn-through area S. By both edges 6a, ? Fold the above-mentioned bent piece 6. When the bent part 7 is formed, if the melted part S is deep, a part of the melted part S becomes rough in appearance as shown in FIG. Put it away.
従って、本発明は突合せて溶接した端部に発生する欠損
部分が外観上あられれないようにするものである。Therefore, the present invention is intended to prevent the defective portion that occurs at the butted and welded ends from appearing visually.
本発明は突合せ部分の両端を残して突合せ部分を溶接し

Then, an intermediate material 21 shown in FIG. 2 is formed. Next, butt against the cut end pressure, Figure 3 (a), (b
), this butt portion 22 is welded.

のものである。During welding, the lower electrode 23 was provided in the width direction at the center of the lower electrode 23 made of copper, tungsten alloy, or the like. The abutting portion 22 is positioned above the III groove 24, and one end 22a of the abutting portion 22 is fitted into a horizontal recess 23c formed in the rising wall portion 23b of the side electrode 23a. The portion 22a is covered with the covering portion 23d. The length l of the end portion covered by this covering portion 23d is approximately 0.5 mm. The side electrode 23a rises upward from the side of the lower electrode 23 and is electrically integrated with the lower electrode 23.

装着する。Next, an arc is generated from the covering portion 23d of the side electrode 23 and scanned along the abutting portion 22 in the opposite direction. The arc is stopped at a position approximately 0.5 degrees from the opposite terminal 22f. As a result, welding is performed with 0.5 length left at the end of the abutted portion, and a ring-shaped body is obtained. Next, after grinding and polishing the welded part as necessary, both edges 22h, 22h of the annular body including the non-welded part 22e are bent inward, as shown in FIG. With the curved piece 6 fitted into the recess 5 of the foil cover 2, bend the outer peripheral end toward the back surface of the foil cover 2 to form the bent part 7.
is formed, integrated with the foil cover, and attached to the foil rim 3.

なものとできる。According to the above method, both edges including the non-welded portion 22e are bent inward, so that the non-welded portion 22e does not appear rough. That is, according to the present invention, the length of the non-welded portion 22e can be set in advance to, for example, about 0.5 mm, and therefore, if both edges are bent inward using the center side from this 0.5 length position as a fulcrum, good. If the depth of the melt-through part S differs from product to product as in the past, it is difficult to set the length of the part to be bent, and if this length is short, the burn-through part S will appear in appearance. , the present invention can improve the appearance of all products.
