AUTOMATIC HORIZONTAL POSITION ONE SIDE WELDING METHOD

PURPOSE:To provide a welding method in which the number of passes is reduced in a gas shielded arc welding. CONSTITUTION:A wire that is 1.4-1.6mm of diameter and superior in crack resistance is used for a first electrode (preceding electrode) 15, and a flux cored wire that is 1.6mm of diameter and s...

Zusammenfassung:	PURPOSE:To provide a welding method in which the number of passes is reduced in a gas shielded arc welding. CONSTITUTION:A wire that is 1.4-1.6mm of diameter and superior in crack resistance is used for a first electrode (preceding electrode) 15, and a flux cored wire that is 1.6mm of diameter and superior in workability is used for a second electrode (succeeding electrode) 16. The electrodes (wire) are separated by 50-80mm in the front and rear directions and by 3-8mm in the up and down directions; a 60-80 deg. horizontal angle and a 35-45 deg. vertical angle are given to the wires; and while weaving is obliquely performed by using a 280-320A electric current, a bead welding by a lap welding method is performed to finish an L-shaped groove face upto a 20mm thickness by one or two operations.
