Abstract: Laser channels of a simultaneous laser welding system are controlled using profiling where there is a profile associated with each laser channel for each active weld step of the laser channel and the laser channels are controlled using the respective profiles for each active weld step of each laser channel. In an aspect, the actuator of the simultaneous laser welding system is controlled using one or more of laser light intensity amplitude profiling, force profiling, distance profiling and laser energy profiling. In an aspect, one or more conditions are used to determine when to transition from a step of a cycle of the simultaneous laser welding system. The conditions can be any of time, accumulation of laser energy, actuator position, and actuator force.
