摘要: PROBLEM TO BE SOLVED: To provide a laser beam machining method that has fast speed and prevents welding defects, when performing seam by repeating pulselike irradiation while scanning at high speed. SOLUTION: A linear shape is formed of first pulse. After the pulse before second pulse, driving part returned fixed distance in original direction. Then, scanned forward again conducted overlapping end each weld zone. COPYRIGHT: (C)2007,JPO&INPIT
