Abstract

PURPOSE:To prevent sagging of a deposited metal and to form a defect-free bead part by interposing a coating layer contg. a material having layer crystal lattice structure between materials to be welded and an end tab and pressing these materials while bringing the materials into contact with each other under pressure. CONSTITUTION:A coating layer 12 consisting of a material having layer crystal lattice structure (boron nitride, etc.) is interposed between the ends of materials 9, 10 to be welded and an end tab 8 having a suitable groove part 11 complying with the required groove angle and while these materials are brought into contact with each other under pressure, the materials are welded from above the groove. Then the molten metal flows into the groove part 11 of the end tab 8, thereby forming the end part 13 of a weld bead. Since the layer 12 covers the surface of the tab 8, the uniform end part 13 is obtd. without melting and welding the part 11 and without hampering the fusion of the materials 9, 10.

However, one side of the end tab (4) melts due to the welding heat, and it reacts with the molten weld bead, forming a slag layer that deforms and wears out, making it impossible to reuse the tab. This is not possible, and even if you use the front and back sides, you can only use it twice, and after that, you will need to find a new end tag (4) for welding.

The layered crystal lattice structure material in the present invention has extremely excellent heat resistance, electrical insulation, and mold releasability, has good peelability between the molten metal and the end tab, and has excellent peelability between the end tab and the end of the welded material. Due to its self-lubricating property, which is oriented without any gaps according to the roughness of the surface, the end tab itself will not melt even if an overheated part occurs as welding progresses. Therefore, there will be no fusion phenomenon with the welded material, and after welding is completed. The material to be welded and the end tab can be quickly separated, and the grooves provided in the end tab are not damaged by fusion, so they can be reused many times when welding different materials to be welded.

The edge of the weld bead obtained by welding has no combustion components, so it does not generate gas and damage the weld and create blowholes, and it is free from components that turn into slag, such as flux and oxide ceramics. This eliminates the possibility of a large amount of slag adhering to the surface of the weld bead end, or of slag being trapped inside the weld bead, resulting in extremely beautiful and sound welding without any defects. Welding is what is accomplished.
