As described in Japanese Unexamined Patent Publication (Kokai) No. Hei 5-50813 and Japanese Patent Publication No. 2-50813, construction by resistance welding that can be joined in a short time has become common. FIG. 4 is a perspective view showing a main part of the main pipe, which is a branch pipe orthogonal or oblique to the head pipe, resistance-welded. The main pipe 2 is fixed by a lower electrode 3 made of copper or a copper alloy having excellent conductivity and heat conductivity. The head pipe 1 is inserted through the center electrode 4, the center electrode 4 is fixed so as to be able to descend by the upper electrode 5, and the main pipe 2 is connected to the head pipe 1.
And resistance welding while applying pressure. The main pipe 2 is clamped by the lower electrode 3 and the head pipe 1
The upper surface is formed so as to be able to abut on the circumferential portion, and a weld metal receiving groove 6 is provided above a support surface for supporting the main pipe 2, thereby suppressing the formation of burrs on the outer surface. Also, the main pipe 2
The inner surface is welded by applying an internal pressure (about 2 to 6 kgf / cm 2 ) with air G to reduce the formation of burrs on the inner surface.

面にバリが生じて接合強度が低くなる。In recent years, light and strong titanium materials having excellent corrosion resistance have been used in various fields, and their Young's modulus is about half that of steel, which is capable of absorbing vibration. Was. However, when the main pipe and the head pipe of the titanium frame are resistance-welded while applying internal pressure to the inner surface of the main pipe with air, titanium is easily oxidized and nitrided at high temperatures, so both the weld metal and the heat-affected zone are oxidized and nitrided. Hardens and becomes brittle. When an inert gas is used instead of air, it is difficult to increase the internal pressure, and burrs are formed on the inner surface to lower the bonding strength.

しなけれぱならない。Therefore, as shown in FIG. 5, the tip 7 of the main pipe 2 which is the joint of the main pipe 2 with the head pipe 1 is butted to increase the wall thickness of the pipe.
That is, it was necessary to increase the bonding area and perform the bonding. This batting process takes a long time to process, so that the working efficiency is poor, and the joining area is large, so that the welding heat input must be large.

In the case of cross joining, the joining portion may be displaced from a target location due to the pressure contact force at the time of resistance welding, and the product yield is deteriorated.

制する必要もない。As shown in FIG. 2, the main pipe 2 is extrapolated to the auxiliary pipe 8 and resistance welding is performed on the head pipe 1 together with the auxiliary pipe in a short time. The main pipe 2 is pressed by an auxiliary pipe 8 having a role of reinforcing a joint having an outer diameter slightly smaller than the inner diameter of the main pipe 2 and clamped by the lower electrode 3 shown in FIG. Since the support surface has the weld metal receiver 6, no burrs are formed on the inner and outer surfaces of the main pipe 2 due to oxidation of the joint, and the bead appearance has an ideal shape. Therefore, there is no need to finish the surface after welding, and it is not necessary to suppress the formation of burrs by applying an internal pressure with an inert gas from the inner surface of the main pipe 2.
【００１３】また、接合部の酸化、窒化やバリの発生が

イプ８と一体に接合されて接合断面が大きいので、高い
接合強度が得られる。Further, since there is no occurrence of oxidation, nitridation or burrs at the joint portion, and since the main pipe 2 is integrally joined to the head pipe 1 and the auxiliary pipe 8 and the joint section is large, high joining strength can be obtained.

抵抗溶接しても溶接位置がずれることがない。Furthermore, after the auxiliary pipe 8 is joined to the head pipe 1, the main pipe 2 is extrapolated to the auxiliary pipe 8 and joined to the head pipe 1, so that the oblique angle θ of the main pipe 2 to the head pipe 1 is small. The welding position does not shift even when resistance welding is performed while applying pressure.

A structure having a large vibration absorption can be obtained.
