Zusammenfassung: | 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 |
