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

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.

With the increase in environmental awareness and attention to new energy vehicles, the global demand for new energy and energy storage is also growing, and the demand for lithium batteries is also increasing.

Dear, We will participate in the SCHWEISSEN & SCHNEIDEN 2023 exhibition in Germany from September 11th to 15th, and sincerely invite you to visit us. We are looking forward to meeting you!
