| description | To reduce a sputter generation amount using a simple welding power source device.SOLUTION: A welding device 1 includes: a welding power source device 8; a welding torch 7; a contact chip 2 which is mounted on the welding torch 7 and applies a voltage given to a welding electrode 12 from the welding power source device 8; a gas nozzle 5 mounted on the welding torch 7; a gas cylinder 16 storing first shield gas; and a gas supply part 6 which supplies gas of the gas cylinder 15 storing the second shield gas to the gas nozzle 5. Preferably, the gas supply part 6 includes: an electromagnetic valve 13 which supplies the first shield gas (Ar gas) while periodically increasing and decreasing the first shield gas; a first flow meter 17 which measures a flow rate of the first shield gas (Ar gas) passing through the electromagnetic valve 13; and a second flow meter 18 that measures a flow rate to which the second shield gas (COgas) is supplied.SELECTED DRAWING: Figure 1
【課題】簡便な溶接電源装置を用いてスパッタ発生量を低減させる。【解決手段】溶接装置１は、溶接電源装置８と、溶接トーチ７と、溶接トーチ７に取り付けられ溶融電極１２に溶接電源装置８から与えられる電圧を印加するコンタクトチップ２と、溶接トーチ７に取り付けられたガスノズル５と、第１シールドガスを貯留するガスボンベ１６および第２シールドガスを貯留するガスボンベ１５のガスをガスノズル５に供給するガス供給部６とを備える。好ましくは、ガス供給部６は、第１シールドガス（Ａｒガス）を周期的に増減させながら供給する電磁弁１３と、電磁弁１３を通過する第１シールドガス（Ａｒガス）の流量を測定する第１流量計１７と、第２シールドガス（ＣＯ２ガス）が供給される流量を測定する第２流量計１８とを含む。【選択図】図１ |
