Abstract

PURPOSE:To perform the padding work with good workability, and performing the padding weld in the cavity which is formed by pressing a concavity shaped copper chiller against the inner surface part of the cylindrical body, and subsequently performing the padding on the unpadded part by other copper chiller supported by the padded part. CONSTITUTION:A concavity shaped copper chiller 2a is installed to the hole inner surface part 3 in the gudgeon hole, etc. 1, the center of the base plate 6 of the welding equipment body is located in the center of the gudgeon hole, and each welding nozzle 23 of the welding equipment 18 provided on the tip of the arm 13 is inserted into the cavity 5 between the copper chiller 2a and the hole inner surface part 3. Subsequently, the motor 7 and the welding equipment 18 are operated, and the padding weld is performed in the cavity 5, shaking the nozzle 23 in the circumferential direction. After that, a circular copper chiller 2b is supported by the padding welded parts 4, 4', and the padding weld is performed to the cavity 5 of the unpadded part between the hole inner surface part 3 and the copper chiller 2b in the same way as the above procedure.
