はイナートガスアーク溶接による場合に比べて溶接金属
中の酸素量が多くなるのが必然とされていた。In general, when the amount of oxygen in the weld metal increases, more sulfuric acid compounds remain as inclusions, resulting in a decrease in notch toughness and, therefore, impact value.In inert gas arc welding, the arc atmosphere is controlled by external shielding gas. The amount of oxygen in the weld metal can be significantly reduced because it can be shut off with an inert gas, but in coated metal arc welding and submerged arc welding, gas cannot be supplied from the outside because of the coating agent and flux. These welding methods inevitably result in a higher amount of oxygen in the weld metal than when using inert gas arc welding.

る。The hollow wire (l1k) must be made of a hoop material of the same material as a bare welding wire and formed into a chain so that it does not buckle and deform when it is fed to the contact wire 1-(7). The nozzle of the shielding gas supply device is inserted into the hollow wire (in Fig. 1) during forming 11 in the hollow wire forming machine IIK, and the inside of the hollow wire is prevented from leaking. The trap is designed so that shielding gas is blown towards the tip of the navel.
