Why use a flat-top laser beam?

A. Difficulties in welding copper Since copper has a very low absorption rate of near-infrared laser at room temperature, most of the incident laser will be reflected during the welding process, resulting in severe energy loss of copper during the laser welding process and low laser energy utilizati

As long as the gas type, gas flow rate, and injection method are selected correctly, the ideal effect can be achieved. However, incorrect use of shielding gas can also have adverse effects on welding.

Laser welding can be achieved using continuous or pulsed laser beams. The principles of laser welding can be divided into heat conduction welding and laser deep penetration welding.
