What kind of material can be welded by laser welding machine and how thick can it be welded?
When choosing a welding machine, it is always impossible to choose between an old welding machine and a laser welding machine. The reason everyone is so hesitant is because they do not know enough about laser welding machines.
Someone might ask: "What is a laser welding machine? What products can the laser welding machine weld? What are the problems in the application industry of the laser welding machine?
Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation is transmitted to the inside of the material through heat, melting the material to form a specific molten pool. This is a new type of welding method,
Mainly used for welding thin-walled materials and precision parts.
It can realize spot welding, butt welding, lap welding and so on. The width of the weld is small, the deformation of the heat affected zone is small, the welding speed is fast, and the weld is flat. , The welding quality is high, the precision can be accurately controlled, the positioning accuracy is high, and the automation is easy.
Laser welding machine is usually called laser welding machine, energy negative feedback laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment
With the continuous development of science and technology, traditional welding methods can no longer meet the special requirements of many industrial technologies for materials. The advantages of laser welding machine are low bonding strength and wide heating area,
Especially in many industries that have gradually replaced traditional welding methods. Welding method.
The industry applications of laser welding machines are as follows:
Bathroom industry: water pipe joints, tees, valves, shower welding.
Glasses industry: stainless steel, titanium alloy and other materials, buckles, precision welded outer frames and other parts.
Hardware industry: welding complex stamping parts and castings,
Such as impellers, kettles and handles. Automobile industry: engine cylinder head gasket, hydraulic tappet sealing welding, spark plug welding, filter welding, etc.
Medical industry: welding of stainless steel seals, medical equipment, medical equipment, structural parts.
Electronics industry: sealing welding of solid state relays, welding of connectors and connectors, metal shells and structural parts such as MP3. Welding motor shells and wires, optical fiber connectors, etc.
Household hardware: kitchenware, stainless steel door handles, electronic components, sensors, watches, precision machinery, communications, handicrafts and other industries, automotive hydraulic tappets and other high-strength products welding products.
Almost all of these industries use laser welding machines.
Advantages of laser welding machine
Concentrated energy, no pollution, small solder joints, wide range of weldable materials, strong applicability, high efficiency and fast welding speed.
At the same time, the following requirements also apply to laser welding:
1. Products with weld seam requirements. Products that need to be welded are welded by laser welding, not only small welds but also no welding
2Highly automated products In this case, the laser welding equipment can be manually programmed, and the path is automatic.
3 The product can stop welding at room temperature or under special conditions, and the laser welding equipment is easy to install. For example, if the laser passes through an electromagnetic field, the beam will not move. The laser can be welded in air and certain gas environment, and can be welded through glass or transparent beam.
4 Some inaccessible parts require laser welding equipment, which can weld inaccessible parts and realize non-contact long-distance welding. Long-distance welding, and has high sensitivity. Especially in recent years, YAG laser processing technology has adopted optical fiber transmission technology, making laser welding technology more popular
