Application:
Galvanometer scanner in laser welding:
Galvo scanning laser welding is a welding method of high accuracy realized through a beam of laser with great energy manipulated by the galvo scanner. In this case, laser radiation heats up a work piece’s surface and melts it into a specified molten pool with inward heat infiltrating from the surface through adjusting pulse laser width, peak power and repeating frequency.
