Laser welding machines, also commonly referred to as laser welders or laser beam welders, are equipment used for laser welding in material processing.

Laser welding involves using high-energy laser pulses to locally heat small areas of materials. The energy from the laser radiation diffuses into the material's interior via heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, primarily designed for thin-walled materials and precision parts welding. It can achieve spot welding, butt welding, overlay welding, and seal welding, with high depth-to-width ratios, narrow weld widths, minimal heat-affected zones, and minimal deformation. The welding speed is fast, with smooth and aesthetically pleasing welds that require no or only minimal post-weld treatment. The weld quality is high, free of pores, controllable, with a small focal spot, high positioning accuracy, and is easily automated.

Laser welding machines, also known as laser welders, energy-negative feedback laser welding machines, laser welding equipment, laser cold welding machines, laser argon welding machines, and various other names such as laser welding devices, can typically be categorized by their working methods into manual laser welding machines (laser mold welding machines), automatic laser welding machines, jewelry laser welding machines, laser spot welding machines, fiber-optic transmission laser welding machines, galvanometer welding machines, handheld welding machines, and more. Laser welding equipment includes sensor welding machines, silicon steel sheet laser welding equipment, and keyboard laser welding equipment.

Weldable graphics include points, lines, circles, squares, or any flat shapes drawn with AUTOCAD software.
