Systems and methods to control laser application for handheld laser welding torches and laser welding equipment

A laser welding system, comprising:

• a laser source to generate laser power to perform a welding operation;
• a handheld laser welding torch to direct the laser power to a workpiece via a nozzle, wherein the nozzle is configured to output a laser beam;
• a laser beam controller to control application of the laser beam from the handheld laser welding torch to the workpiece as a focal point following one or more wobble movements defining a wobble path, the one or more wobble movements being coordinated with the laser power relative to a position of a focal point at the workpiece along the wobble path;
• and
• a sensor to measure one or more weld characteristics of a weld bead or the workpiece.

A collaborative robot laser welding system, comprising:

• a laser source to generate laser power to perform a welding operation;
• a handheld laser welding torch to direct the laser power to a workpiece;
• and
• a robotic arm to support the handheld laser welding torch;
• a laser controller to:
• receive a first input from a user corresponding to position or movements of the collaborative robot;
• receive a second input corresponding to a welding process;
• and
• control generation of the laser power from the laser source and the positions or the movements of the robotic arm based on the first and second inputs.
