METHOD AND APPARATUS FOR AUTOMATIC WELDING

A welding expectation path (l) is taught beforehand, and an operation for striking an electric arc (250) is executed at a point (AS) on the path. If the electric arc does not appear, the operation for striking the electric arc is executed at a different point on the path (l). When the electric arc h...

Zusammenfassung:	A welding expectation path (l) is taught beforehand, and an operation for striking an electric arc (250) is executed at a point (AS) on the path. If the electric arc does not appear, the operation for striking the electric arc is executed at a different point on the path (l). When the electric arc has appeared, a welding torch is once returned to a welding start expectation point (S) while the electric arc (250) is held, and it performs welding from the welding start expectation point (S) toward a welding end expectation point (E).
