英文摘要	By using the improved welding torch, coupled arc AA-TIG welding experiments were carried out with SUS304 plate as the base metal. The differences of arc morphology and weld shape between AA-TIG welding and traditional TIG was compared. Meanwhile the effects of major parameters to AA-TIG weld bead as well as the weld mechanical properties were investigated. The results showed that the welding parameters including oxygen flowrate, electrode spacing and arc length had significant influences on the weld penetration of coupled arc AA-TIG welding. Under the same total current, the welding bead of coupling AA-TIG was narrower and deeper when comparing with conventional TIG welding. The weld presented better mechanical properties. For 12 mm thickness SUS304 stainless steel plate, the weld penetration of one pass exceeded 11mm, the weld depth/width ratio reached 1.3. The welding productivity was improved dramatically. © 2017, Editorial Board of Transactions of the China Welding Institution, Magazine Agency Welding. All right reserved.
