Hybrid welding is to combine the fifiber laser and the diode laser into one laser beam through the optical lens group, which is output simultaneously and coaxial in space. The output energyof diode laser and fifiber laser can be adjusted independently, so hybrid welding has the advantages of both laser welding. It can not only achieve the deep penetration welding effffect of fifiber laser, but also have the advantages of diode laser, which is preheating, slow cooling and smooth welding seam.

The wavelength of diode blue laser is 450nm, which can be greatly absorbed by high-reflflection metal material, thus it can realize high-stability and high-quality welding of gold, silver, copper and their alloys. The blue laser has high beam quality and strong penetration ability. It can achieve penetration welding of 1.5mm copper, 2mm manganese copper, 2mm nickel-chromium alloy and so on. The maximum continuous laser power output of 1500W can achieve a welding speed of more than 200mm/s, which greatly improves the production capacity. It can be used in automotive parts, passive components, new energy power batteries, electronic components and other industries.

Laser solder jetting welding uses a laser as a heat source. A single solder ball is transported to the nozzle through the solder ball conveying system, heated to a molten state by a laser beam in an inert gas atmosphere, sprayed to the surface of the welding workpiece, infiltrated and diffused to form a bonding layer, which results in a firm connection.

The laser curing system uses a diode laser as the light source. After beam shaping, a uniform rectangular light spot is obtained, and the surface of the part is irradiated for uniform heating. The glue (low/medium/high temperature) is rapidly heated up to the curing temperature, and the liquid is changed to a solid state to achieve joining of the parts.

The solder paste laser welding system adopts an automatic solder paste placing device, and the solder paste is applied to the products to be welded. The solder paste and the workpiece are heated by the laser. And when the solder paste is melted, it wets the surface of the product, diffffuses and forms a bonding layer to achieve a stable connection.

This system uses CW fifiber laser and AOB adjustable beam mode laser as the light source. The galvanometer is used to control the welding path, and various welding paths such as spiral point welding, concentric point welding, s-shape fifilling welding, sinusoidal swing welding, and fifigure-8 swing welding are realized. By editing the waveform and adjusting the duty cycle to precisely control the heat input, it can achieve lap welding or butt welding of stainless steel, copper, aluminum, and nickel with a thickness of 0.05-8mm.

This system uses QCW fifiber laser as the light source. Various welding methods such as continuouswelding, quasi-continuous welding, and single-pulse point welding are realized by controlling the welding path with the galvanometer. The heat input is precisely controlled by editing the waveform and adjusting the duty cycle, so as to realize lap welding or butt welding of metal sheets, especially stainless steel, nickel, copper, etc.

This system uses a nanosecond fifiber laser as the light source. The welding path is controlled by the scanning pattern of the galvanometer, and the heat input is precisely controlled by high-frequency pulses, so as to realize metal sheets welding, especially dissimilar metals such as stainless steel, copper, aluminum, and nickel.
