Title:
BUTT WELDING METHOD USING HIGH ENERGY BEAM
Document Type and Number:
Japanese Patent JP3267811
Kind Code:
B2
Abstract:
PURPOSE: To provide a welding method which controls gaps easily and which makes a filler wire unnecessary.
CONSTITUTION: On an end of one member 1, an over-lapping part to over-lap an end of the other member 3 is formed, the end parts of both members are butted while over-lapping this over-lapping part on the end of the other member, at first the over-lapping part 2 is molten with a high energy beam 4, successively, the ends of both members are welded. Because the over-lapping part is molten firstly, the blow-through can be prevented, so the control of gaps is made remarkably easily, and the working efficiency is improved.
