Zusammenfassung: | To provide a welding system in which an electromagnetic valve is provided at a shield gas passage and which is suitable for improving deterioration of welding work efficiency.SOLUTION: A welding system A1 of the invention includes: a welding torch 1; a wire delivery device 2 which delivers a welding wire to the welding torch 1; a shield gas supply source 5 which supplies shield gas to the welding torch 1; a shield gas passage 6 which flows the shield gs from the shield gas supply source 5 to the welding torch 1 through the wire delivery device 2; and an electromagnetic valve 7 which is provide at the wire delivery device 2 and opens or closes the shield gas passage 6. The shield gas passage 6 is provided with a non-return valve 8 which allows flow of the gas from the shield gas supply source 5 side to the welding torch 1 side and blocks the flow of the gas from the welding torch 1 side to the shield gas supply source 5 side.SELECTED DRAWING: Figure 1
【課題】シールドガス流路に電磁弁が設けられた溶接システムにおいて、溶接作業効率の低下を改善するのに適した溶接システムを提供する。【解決手段】本発明の溶接システムA1は、溶接トーチ1と、溶接トーチ1へ溶接ワイヤを送給するワイヤ送給装置2と、溶接トーチ1へシールドガスを供給するシールドガス供給源5と、シールドガス供給源5からワイヤ送給装置2を介して溶接トーチ1までシールドガスを流すシールドガス流路6と、ワイヤ送給装置2に設けられ、シールドガス流路6を開閉する電磁弁7と、を備え、シールドガス流路6には、シールドガス供給源5側から溶接トーチ1側へのガスの流れを許容し、かつ溶接トーチ1側からシールドガス供給源5側へのガスの流れを阻止する、逆止弁8が設けられている。【選択図】図1 |
