What Is a Core-Ring Laser Welding Machine?

A Core-Ring Laser Welding Machine uses two laser beams that work together during welding: a high-energy center beam for deep penetration and a surrounding ring beam for controlled heat input. The ring beam preheats the material, stabilizes the molten pool, and slows cooling, producing a smoother and more stable welding process.

This beam configuration is well suited for aluminum, copper, stainless steel, carbon steel, and other materials that require stable heat control. Compared with conventional single-beam laser welding, it reduces spatter and porosity, improves weld formation, and maintains stable penetration during continuous welding. Independent adjustment of the center and ring beams allows the heat distribution to be matched to different materials, plate thicknesses, and welding applications.

Core-ring laser welding machines are widely used in steel structure fabrication, pressure vessel manufacturing, shipbuilding, construction machinery, heavy equipment, and other industrial applications where weld quality and production stability are essential.

Working Principle

A Core-Ring Laser Welding Machine uses two laser beams during welding. The center beam delivers high energy density for deep penetration, while the ring beam surrounds the weld area to control heat input and stabilize the molten pool.

The ring beam heats the material before welding, reducing thermal shock and laser reflection on high-reflectivity metals. Independent adjustment of the two beams allows the welding parameters to be matched to different materials, thicknesses, and joint conditions.
