この発明は、ガスシールドアーク溶接による肉盛ｌ＠接
力方法関し、横向きあるいは立向きの溶接姿勢において
も良好な溶接品質を得ることを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a build-up l@contact method using gas-shielded arc welding, and an object of the present invention is to obtain good welding quality even in horizontal or vertical welding positions.
従来、円筒容器等の各姿勢の肉盛溶接は、ｗｔ覆アーク

れない。Conventionally, overlay welding in various positions for cylindrical containers and the like has been performed by wt covered arc welding, but since this covered arc welding is performed manually, it is not efficient and quality efficient.
そこで、電極をタングステンの非消耗性電極とし、沼援

接品質をイ（することができない。Therefore, we decided to use a tungsten non-consumable electrode and use it as a non-consumable electrode. Using the gas-shielded arc welding force method in which 111 is initially transmitted with an inert gas, automatic R4 welding is performed in which the filler metal is automatically fed and the torch is automatically moved. However, in overlay welding in a horizontal or vertical welding position, the bead shape and welding density are affected by the flow of molten metal, making it impossible to achieve good welding quality.

ことを特徴とする肉盛溶接ツノ法である。This light 11 was created keeping in mind the -MW point, and in accordance with the overlay welding method using gas shield arc welding, a control gas nozzle is provided in the torch nozzle from which the electrode is led out, and the control gas nozzle, l: ! This is a build-up welding horn method characterized by blowing the control gas No. 7 to the tip of the arc generated from the electrode and directing the arc to the filler metal 11111 located at the support of the welding part.

接品質を得ることができる。Therefore, the control gas from the control gas nozzle is applied to the tip of the arc to assist the welding part i1'? Since the spray is directed toward the filler metal side, the arc is assisted, and the sideways position has the effect of pushing down the flow of molten metal even in an upright welding position. Because the arc is directed toward the filler metal, the amount of welding increases even at rotary bath welding current values, and the width of the arc expands perpendicular to the welding direction, resulting in a smooth bead shape and good welding quality. can be obtained.
