向上する立向き溶接方法を提供することを目的とする。If the base material is a material with good heat conductivity, such as copper or copper alloy, only a small amount of the base metal can be melted by arc heat, and depending on the heat conduction of the molten welding wire, almost no base metal can be melted. Cannot be melted. Accordingly, welding could not be done without preheating to a high temperature. The present invention utilizes a part of the molten metal to give it a child heating effect and discharges the other molten metal to the outside, thereby controlling the penetration shape without preheating even for materials that conventionally required preheating. The purpose of the present invention is to provide a vertical welding method that improves the quality of welded parts.

御した溶接ができる。FIG. 1 shows the vertical welding configuration of the subordinate. FIG. 2 shows one embodiment of the present invention, and FIG. 3 is a sectional view thereof. Welding wire 4 and shielding gas are supplied from torch 3. Line both sides of the welding area with 2 pads. The deposit 2 has an outlet 2a for discharging excess molten metal and a groove 2b for collecting a portion of the molten metal. With the start of molten metal, the molten metal accumulates in the groove 2b of the metal 2. The molten metal of the welding wire that has exceeded the depth h of the groove 2b is discharged to the outside through the discharge port 2a.
Welding progresses by moving the pad 2 upward. The molten metal that has accumulated in the groove 2b of the pad 2 is the base material 1.
Acts as a preheating heat source. By controlling the moving speed of the pad 2 (in the direction of the arrow in Fig. 3), the amount of molten metal discharged from the discharge port 2a is adjusted, and the degree of heating of the molten metal 5 accumulated in the groove 2b by arc heat is adjusted. Therefore, the temperature of the molten metal 5 and the heat effect of the base material 1 can be adjusted. Furthermore, the direct influence of the arc on the base metal 1 can be adjusted, and even materials with good heat conductivity such as copper and alloys can be welded without the need for child heat from a separate heating heat source. By controlling the moving speed of the pad 2 in this way, the penetration of the base material can be controlled. As described above, according to the present invention, the molten metal discharge port and a part of the molten metal pooling groove are provided in the padding for vertical welding, so the molten metal in the pooling groove acts as a preheating heat source, and the padding is moved. By controlling the speed, the amount of molten metal discharged to the outside can be adjusted, and welding can be performed with a controlled penetration shape of the base metal.
