Laser Welding Machine FAQs
What is the principle of laser welding machine?
Laser welding is a process that uses laser energy to heat metal materials, melting them during the heating process and forming welds, thereby achieving the purpose of welding. Lasers transmit energy through undulating electromagnetic waves, which can be guided to the welding point through optical fibers. When the laser beam irradiates the surface of the workpiece, it will be absorbed and converted into heat energy, causing the workpiece to locally heat up until it melts or reaches the temperature required for welding. As the laser beam moves, the molten pool will also move with it, leaving a complete weld on its path. The welding speed is fast, the weld is small, beautiful and the welding is strong.
What are the classifications of laser welding?
- Handheld laser welding machine
- Automatic laser welding machine
- Intelligent robot laser welding machine
What are the components of a laser handheld welding machine?
The laser handheld welding machine is mainly composed of laser, optical fiber transmission system, welding head, control system and cooling system.
What are the advantages of handheld laser welding machines?
Handheld laser welding machine has fast welding efficiency, compact machine and easy operation, which greatly improves work efficiency. Compared with current fiber optic transmission welding, it has higher electro-optical conversion efficiency, better beam quality, less maintenance costs and higher welding speed. The laser welding machine has a high degree of automation and a simple welding process. The non-contact operation method can meet the requirements of cleanliness and environmental protection. Using laser welding machines to process workpieces can improve work efficiency. The finished workpieces have beautiful appearance, small weld seams, large welding depth, and high welding quality.
What are the application fields of fiber optic handheld welding machines?
Mainly aimed at large and medium-sized sheet metal, cabinets, chassis, aluminum alloy door and window frames, stainless steel wash basins, etc. Fixed position of large workpieces, such as inner right angles, outer right angles, flat welding, etc.
In which industries can laser handheld welding machines be used?
Handheld welding machines are widely used in the bathroom industry, glasses industry, hardware industry, automotive industry, medical industry, electronics industry, medical equipment, home furnishing, kitchenware, bathroom and other industries.
For example, cabinets, kitchens, bathrooms, stair elevators, shelves, ovens, stainless steel door and window guardrails, distribution boxes, triangular valves, sensors, stainless steel sinks, tap water pipe fittings, stainless steel round pipe tee elbows, floor drains and other complex irregular welding processes, doors Handle door locks, thermos cups, kitchen utensils and tableware, stainless steel home and other industries
What is the difference between handheld laser welding machine and traditional argon arc welding?
Energy consumption comparison: Compared with traditional arc welding, handheld welding machines save about 80% to 90% of electric energy and can reduce processing costs by about 30%.
Welding effect comparison: The handheld welding machine can complete the welding of dissimilar steel and dissimilar metals. High speed, small deformation and small heat affected zone. Welds should be beautiful, smooth, free of pores/small pores and contamination. Handheld welding machines enable micro-opening parts and precision welding.
Follow-up process comparison: When the hand-held welding machine is used, the heat input is low, the workpiece deformation is small, and a beautiful welding surface can be obtained without or with simple processing (depending on the requirements of the welding surface effect). Handheld welding machines can significantly reduce labor costs for large polishing and leveling processes.
