Automobile industry
The automotive industry is the most mature and widely applied field for laser welding. Laser welding is used to connect automotive frame components such as the roof, side panels, and doors, which not only reduces weight but also improves the strength and sealing of the vehicle body. In addition, laser welding technology is also used in the battery and motor parts of new energy vehicles, such as welding the positive and negative electrodes of battery cells, welding the busbars, and welding the battery casing.
Medical devices
The weld seams produced by laser welding are clean and smooth, making it highly suitable for medical devices that require high cleanliness and precision. Common applications include sealing welds for pacemakers, welding of joint implants, and welding of precision stainless steel surgical instruments.
Sheet metal fabrication
Laser welding produces smooth weld seams with good sealing and an attractive appearance, making it one of the most commonly used welding processes in sheet metal fabrication. Many enclosures and cabinets are manufactured using laser welding, such as distribution boxes, electrical control cabinets, household appliance housings, and stainless steel kitchen cabinets.
Electronics
Laser welding has a small heat-affected zone and high precision, allowing laser energy to be accurately focused on a tiny welding area. This effectively prevents heat generated by welding from damaging surrounding components, making it widely used in sensitive and precisely structured electronic products, such as the midframes of mobile phones, the sealing and connection of sensor housings, and the precision spot welding of internal components in laptops.
