With the emergence of laser welding machine, we have another choice when buying welding machine, but it also brings more problems.
For the laser welding machine, everyone may stay in the old welding process, so that when purchasing the welding machine, they always linger between the old welding machine and the laser welding machine, and do not know how to choose.
The reason why people are so hesitant is that they don’t know enough about laser welding machines.
For laser welding machines, some people will ask the following questions:
What is a laser welding machine?
What products can laser welding machine weld?
What are the application industries of 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 guided to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool.
It is a new welding method, mainly for the welding of thin-walled materials and precision parts.
It can realize spot welding, butt welding, overlap welding, seal welding, etc.
It has these characteristics: high depth width ratio, small weld width, small heat affected zone, small deformation, fast welding speed, flat and beautiful weld, no treatment or simple treatment after welding, high weld quality, accurate control, high positioning accuracy and easy automation.
Laser welding machine is also often called laser welding machine, energy negative feedback laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc.
With the continuous development of science and technology, the traditional welding method can not meet many special requirements for materials in industrial technology.
Laser welding machine is widely used because of its low bonding strength and wide heat affected zone. Especially in many industries, it gradually replaces the traditional welding method.
Industry application of laser welding
The industry application of laser welding machine involves the following industries:
Sanitary industry: welding of water pipe joints, reducing joints, tees, valves and showers.
Glasses industry: precision welding of glasses buckle and outer frame made of stainless steel and titanium alloy.
Hardware industry: welding of impeller, kettle, handle, complex stamping parts and castings.
Automotive Industry: sealing welding of engine cylinder gasket, hydraulic tappet, spark plug welding, filter welding, etc.
Medical industry: welding of medical instruments, stainless steel seals and structural parts of medical instruments.
Electronics industry: seal off welding of solid-state relay, welding of connector, welding of metal shell and structural parts such as mobile phone and MP3. Welding of motor shell and wiring, optical fiber connector joint, etc.
Domestic hardware, kitchenware, sanitary ware, stainless steel door handles, electronic components, sensors, clocks, precision machinery, communications, handicrafts and other industries, as well as automobile hydraulic tappets and other industries with high strength.
Almost all these industries use laser welding machine equipment.
The advantages of laser welding machine are energy concentration, no pollution, small welding spots, wide range of weldable materials, high applicability, high efficiency and high speed.
At the same time, products with the following requirements are also suitable for laser welding.
Products requiring welds
Laser welding equipment is used to weld products with requirements for welds, which not only has small welds, but also does not need solder.
Highly automated products
In this case, the laser welding equipment can be programmed manually and the path is automatic.
Products at room temperature or under special conditions
It can stop welding at room temperature or under special conditions, and the installation of laser welding equipment is simple.
For example, when a laser passes through an electromagnetic field, the beam will not shift;
Laser can weld in vacuum, air and some gas environment, and can stop welding through glass or data transparent to the beam.
Some inaccessible parts require laser welding equipment
It can weld inaccessible parts and implement non-contact remote welding, which has great sensitivity.
Especially in recent years, optical fiber transmission technology has been adopted in YAG laser processing technology, which makes laser welding technology more widely promoted and applied.
