Title:
WELDING METHOD AND WELDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/056965
Kind Code:
A1
Abstract:
A welding method comprises: a disposing step for disposing a nonconsumable electrode (5) so as to lead along a weld line and a consumable electrode (6) so as to follow; a nonconsumable electrode heating step for driving the nonconsumable electrode (5) relatively along the weld line and heating the base material of the joint; a consumable electrode welding step for driving the consumable electrode (6) relatively along the weld line, generating a penetration (11) into the base material, and overlaying deposited metal (10) on the base material; and a nonconsumable electrode heat input control step for performing a control so as to decrease the amount of heat input to raise the temperature by the nonconsumable electrode (5) according to the progress of the welding process.
