METHOD OF CONNECTING PLATE MEMBERS AND METHOD OF MANUFACTURING TWO CONDUIT PIPES

PROBLEM TO BE SOLVED: To exactly perform welding without making a weld bead appearing on a surface. SOLUTION: On a peripheral wall 6 to be used for an exhaust pipe of an engine, a partition wall 6, an oblique surface part 9, a curved surface part 7, an oblique surface part 12 and a target part 13 ar...

Zusammenfassung:	PROBLEM TO BE SOLVED: To exactly perform welding without making a weld bead appearing on a surface. SOLUTION: On a peripheral wall 6 to be used for an exhaust pipe of an engine, a partition wall 6, an oblique surface part 9, a curved surface part 7, an oblique surface part 12 and a target part 13 are formed by bending a sheet of plate. When the target part 13 is projected form a trough bottom of a trough part 14 and an arc is applied from a weld torch 15, the arc reaches the target part 13 without leaking to the oblique surface part 12 and the trough bottom part is exactly welded.
