Title: Tig arc welding method
Inventor: IWASAKI AKIO
IPC: B23K9/167
Filed: 1986-03-11
Abstract: PURPOSE:To improve the sinking effect based on an arc force by forcibly reduce the diameter of the arc generated between an electrode and base metal via an insulator and by making the thermal density of arc larger. CONSTITUTION:The insulator 5 making the hole 4 through which an arc 1 only can pass is interposed between an electrode 2 and base metal 3, then a TIG arc welding is performed. In this case, the ignition of the arc 1 is performed only on unshielding zone 6 due to the arc generation point on the base metal 3 being shielded by the insulator 5. The outer edge part of the arc 1 is cooled due to the cooling effect of the insulator 5 and the arc column becomes smaller with contraction. The thermal density of the arc 1 therefore becomes large and the penetration depth becomes deeper by the larger portion of the thermal density owing to the constant voltage characteristic of a TIG arc welding machine. Namely the sinking effect due to the arc force can be improved because of the heat input efficiency being improved with the thermal density of the arc becoming larger.
