接は実質的に実用化されていない。Generally, one or both surfaces of a galvanized steel sheet are coated with a zinc film. There are cases where it is desired to overlap such galvanized steel sheets and bring them into contact with each other using heat such as an electric arc. When welding another workpiece on top of the zinc coated surface of the treated steel sheet,
During welding, molten zinc and the like are ejected together with gas, creating blowholes on the welding surface and generating spatter (grains of molten 'FtlfS welding material), which are harmful to welding. This not only adversely affects the welding result, but also causes problems such as adhesion to the nozzle of the welding torch or welding electrode, making it impossible to generate an electric arc. For this compelling reason, commercial welding or pin-edge welding of zinc-treated lXi using an electric arc has not been practically put to practical use.

少壬の溶接以外には利用しにくい。If you really want to weld the treated steel plate by welding or lap welding, we recommend that you use 11T at the welding point! Welding is performed using an electric arc after the lead coating has been removed in advance, but it takes a great deal of time to remove the zinc coating, and this welding method is difficult to use for anything other than extremely small-scale welding.

させたことを特徴としている。In this invention, in order to eliminate the drawbacks of the conventional method as described above, when welding the zinc coated surface of the workpiece with another workpiece, at least the welding point between them is It is characterized in that a metal body having a melting temperature equal to or higher than approximately the boiling temperature of zinc and equal to or lower than the melting temperature of the object to be welded is present at the location where the arc is irradiated.

第１図により本発明の一実施例について説明する。Therefore, in this invention, since a metal body is present at the welding location, the metal body has a melting temperature that is above the boiling temperature of zinc and below the melting temperature that is approximately the same as the melting temperature of the object to be welded. Before the zinc boils and vaporizes due to the process, or before the boiling and vaporization of zinc progresses much, the metal body forms an alloy with zinc and a higher boiling point, and further contains the metal material of the workpiece. An alloy with a high boiling point is used to suppress the progress of boiling and vaporization of zinc, thereby preventing the occurrence of blowholes, spatter, etc. [Example] An example of the present invention will be explained with reference to Fig. 1. do.

212 and the zinc coating 21 of the zinc-treated steel Fi2 and welding is performed, the zinc coating 12.21 and copper form an alloy with a boiling point higher than that of zinc during the melting by heating, that is, the welding process. It is thought that an alloy is formed between these and iron, which suppresses the boiling of zinc or limits its progress. As a result, before the iron material of the lower galvanized steel sheet 2 melts during welding and welding is performed, zinc can be completely prevented from boiling and spewing out as gas from within the weld bead, thus preventing spatter and blowholes. does not occur.

By forming an alloy with a high boiling point, it is possible to sufficiently prevent molten zinc from spewing out as a gas or together with the gas from the edge of the galvanized steel sheet l, which is the welding location.

分可能になった。As described above, according to the present invention, when a workpiece to be welded, such as a zinc-treated steel plate on which a zinc coating is formed, is brought into contact with the arc 78, the welding point is heated to a temperature equal to or higher than the boiling temperature of zinc. Since there is a metal body with a melting temperature below the same level as the melting temperature of the object, it is possible to prevent blowholes and spatter from occurring at the welding location, and therefore it is possible to prevent blowholes and spatter from occurring at the welding location. Since there is no adhesion of zinc or the like to the welding material, lap welding and single-lap edge welding of zinc-coated objects to be welded, which had previously been considered impossible, has become fully possible.
