Factory Free Sample Handheld Fiber Laser Welder for Stainless Steel Aluminum Copper Metal Laser Welding Machine with Welding Gun and Nozzles

The main function of the copper nozzle of a laser welding machine is to protect the laser welding head. Laser welding is a high-temperature and high-pressure process that generates a large amount of gas and dust around the welding joint. And these dust and gases can have a negative impact on the quality of the welding joint, and even damage the welding joint. The copper nozzle of the laser welding machine can discharge these dust and gases during the welding process, thereby preventing their impact on the welding joint.
