SYSTEMS AND METHODS FOR LASER WELDING

摘要

A laser welding system (1) is provided. The laser welding system includes a laser source (3) configured to produce a laser beam, beam modifying means (5) configured to split the laser beam into at least two heat source points (30) positioned at a predetermined angle relative to one another along a diagonal intersecting and radially equidistant from a center of a circular weld line (c), the circular weld line being concentric with an object to be welded, rotating means (14) configured to cause rotation of the at least one group of two heat source points or the object to be welded, and controlling means (12) configured to control the rotating means to cause the at least one group of two heat source points to scan substantially all of the circular weld line.
