Title:
LASER WELDING METHOD
Document Type and Number:
Japanese Patent JP3238661
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent unevenness of penetration depth when welding is carried out while a work and a laser welding machine are relatively moved.
SOLUTION: When a laser welding machine is moved to a work for carrying out laser welding along a circular weld line, the laser output is varied synchronizing with the moving speed at a portion where the delay of response for the moving speed command exists at the time of start of welding or completion of moving, so as to even the penetration depth of welding. Thereby, welding strength, durability and the like can be improved.
