Fiber Laser Welding

Laser welding is a highly efficient processing technology that utilizes a high-energy-density laser beam as a heat source to achieve precise joining by melting materials. It is suitable for metals such as stainless steel, aluminum alloy, titanium alloy, and copper, as well as non-metals like plastics and composite materials. It particularly excels in joining dissimilar materials, such as copper-aluminum and steel-plastic. Application areas cover industries including automotive manufacturing, electronics, aerospace, medical devices, sports equipment, furniture manufacturing, jewelry, and mold manufacturing.

For different industries and applications, we provide tailored laser welding solutions, offering various types of laser welding equipment, such as handheld laser welding machines, galvo laser welding machines, jewelry laser spot welders, and mold laser welding machines.

Laser welding is a precise process that results in minimal deformation compared to traditional welding methods. It can be used for any material that can be melted and re-solidified, meaning it's applicable not only to metals like aluminum, copper, and stainless steel, but also to other material types, including certain thermoplastics, glass, and composites.

Conduction welding is a soft welding process where the laser beam slowly melts the metal. During this welding process, the metal's temperature exceeds its melting point and reaches a liquid state but does not turn into a gaseous state. Heat transfer within the metal is similar in all directions. Conduction welding is slower but yields higher weld quality with little to no spatter and less fumes.

Keyhole welding is a rapid welding process that melts and vaporizes the metal, allowing it to penetrate deep into the material. The metal reaches its melting temperature and, in some areas, even its vaporization temperature. Consequently, part of the melt pool is in a gaseous state, which may lead to spatter. Heat transfer within the metal is primarily perpendicular to the laser beam. Due to its faster speed, keyhole welding is highly suitable for high-volume production lines, though it can result in porosity and a larger heat-affected zone.

Laser welding applications are becoming increasingly common and widespread. Laser welding is frequently used in the automotive industry, and also applied in electronics manufacturing, medical device manufacturing, and other sectors.

Yes. Due to the higher heat input and melt pool strength produced by laser welding, its strength is typically higher than that of MIG welding. Laser welding is also several times faster than MIG welding, eliminating the need for multiple passes and avoiding issues of reduced weld strength.
