A comprehensive review of the application fields of fiber laser welding machines (continuous fiber+pulse fiber, mainly for sheet metal, pipe, hardware, and new energy)
Advantages of fiber laser welding: small thermal deformation, precise weld seam, weldability of dissimilar metals, easy automation and integration, divided into continuous fiber welding (thick materials, mass production) and pulse fiber welding (thin parts, precision small parts).
1、 New energy industry (the largest market in terms of usage)
Lithium battery industry
Cell lugs, copper aluminum busbars, explosion-proof valves, cell casings, PACK copper aluminum connectors, CCS integrated busbars, and battery casing seals; Heterogeneous welding of brazed aluminum, stainless steel, and nickel plated steel strips.
photovoltaic
Aluminum frame welding, junction box terminals, silicon wafer leads, energy storage cabinet body sheet metal.
Hydrogen energy/energy storage
Hydrogen fuel cell bipolar plate (ultra-thin stainless steel 0.1-0.3mm), stainless steel flow channel, and water-cooled pipeline sealing welding.
charging pile
Copper bars, aluminum alloy shells, and wiring terminals.
2、 Pipe/Lamp Pole/Sheet Metal Industry (Your main focus is on supporting lamp poles)
Street lamp pole, monitoring pole, power tower
Cone bar joint straight seam welding, flange plate and rod body ring seam welding, hanging ear accessory welding, replacing submerged arc welding/argon arc welding, forming a beautiful appearance without polishing.
Round tube, square tube, special-shaped tube

Home appliances: compressor housing, evaporator copper tube, motor stator housing, stainless steel accessories for washing machines.
4、 Automotive&Engineering Machinery
Body small parts: seat rails, brake valve body, sensor housing, chassis small parts;
New energy vehicles: motor housing, water cooling sleeve, aluminum alloy valve components;
Construction machinery: hydraulic cylinder ports, wear-resistant bushings, and irregular structural components.
5、 Precision electronics, instruments, sensors (main force for pulse fiber welding)
Micro terminals, sensor housings, watch steel cases, eyeglass frames, beryllium copper spring plates, medical stainless steel needle tubes, micro valves, ultra-thin parts with a wall thickness of 0.05-1mm.
6、 Aerospace, military industry
Titanium alloy, high-temperature alloy, aluminum alloy precision structural components, thin-walled sealed chambers, and dissimilar metal welding of hydraulic pipelines.
7、 Wear resistant repair of molds and construction machinery
Die cutting edge welding, wear-resistant layer melting on the surface of hydraulic rod, and local repair of gears (laser cladding integrated machine).
8、 Summary of material adaptation
Easy to weld: 304/316 stainless steel, cold-rolled iron plate, galvanized plate, carbon steel (mainstream material for lamp posts);
Difficult materials: copper, aluminum, copper aluminum dissimilar materials → Optional swing laser welding and dual wavelength fiber optic welding machine;
Thin material<0.5mm: pulsed fiber laser welding; Plate thickness of 1-8mm for mass production: continuous fiber laser welding.
9、 Practical selection suggestions for lamp post factories
Small pole, small accessory: 1000W~1500W handheld fiber optic welding;
