側面図である。 Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a cutaway side view showing an example of a gas pipe and a fixed flange of a conventional gas stove. FIG. 2 is an enlarged view of the main parts of FIG. 1, where a shows the fixing flange, b shows the protrusion of the welded part, and c shows the gas pipe. FIG. 3 is a perspective view of the fixing flange of FIG. 2. FIG. 4 is a cutaway side view of the joint in FIG. 2. FIG. 5 is a cutaway side view of the fixing flange of FIG. 3, in which a protrusion b is formed on the flat surface of the flange in the direction of the welding member. FIG. 6 shows a fixing flange 2 showing an embodiment of the present invention.
The fixing flange 2 is bent into a concave shape facing the outer peripheral surface of the gas pipe 1, and a protrusion 3 is formed along the inside thereof. The gas pipe 1 is placed in the recess from above, and the electrodes 8,
At step 8, projection electric welding is performed. 7 is a sectional side view of the fixing flange 2 of FIG. 6. FIG.
FIG. 8 is a side view of the fixing flange 2 showing another embodiment.

形成するもので、ガス管１の外周面と突出し３と
の溶接面を大きくとれるべく作用する。 Here, to explain the function of the present application, one side of the fixing flange 2 is bent into a concave shape facing the outer peripheral surface of the gas pipe 1, and a protrusion 3 is formed along the bent surface. It acts to increase the welding surface between the outer circumferential surface and the protrusion 3.
突出し３の大きさは凹状の屈曲面に沿つている
もので、ガス管の接触面にわたつて溶接強度が得
られる。尚、突出し３を複数箇配列すればより大
きな溶接強度が得られる。 The size of the protrusion 3 is such that it is along the concave curved surface, so that welding strength can be obtained over the contact surface of the gas pipe. Incidentally, if a plurality of protrusions 3 are arranged, greater welding strength can be obtained.

の効果を有する。 As described above, according to the present invention, a concave curved surface and a protrusion are formed on the inside of the flange side, and the protrusion is joined to the protrusion so as to face the outer peripheral surface of the gas pipe, and projection electric welding is applied to the gas pipe. Since the fixed dimensions of the flange are always accurate when installing the pipe, it is possible to prevent variations in the dimensions of fixing the instrument body and installing the gas tank, etc., and the welding strength is increased, eliminating accidents where the gas pipe cracks. It has the effect of
