At present, laser welding equipment has penetrated into our lives and has been used more and more widely, especially in many industries, gradually replacing traditional welding methods.
The industry application of laser welding machine involves the following industries:
Sanitary ware industry: welding of water pipe joints, reducing joints, tees, valves and showers.
Glasses industry: precision welding of stainless steel, titanium alloy and other materials for the buckle and outer frame of the glasses.
Hardware industry: welding of impellers, kettles, handles, etc., complex stamping parts and casting parts.
Automobile industry: engine cylinder gasket, hydraulic tappet sealing welding, spark plug welding, filter welding, etc.
Medical industry: welding of medical equipment, stainless steel seals and structural parts of medical equipment.
Electronics industry: sealing and breaking welding of solid state relays, welding of connectors and connectors, welding of metal shells and structural components such as mobile phones and MP3. Motor housing and connectors, welding of optical fiber connector joints, etc.
Household hardware, kitchen utensils and bathrooms, stainless steel door handles, electronic components, sensors, clocks, precision machinery, communications, handicrafts and other industries, automotive hydraulic tappets and other industries have high-strength products.
Almost all of these industries use laser welding equipment. The advantages of the laser welding machine are concentrated energy, no pollution, small solder joints, a wide range of weldable materials, strong applicability, high efficiency, and high-speed welding. At the same time, products with the following requirements are also suitable for laser welding.
The working principle of laser welding machine:
Laser welding machine is usually also called laser welding machine, energy negative feedback laser welding machine, laser welding machine, laser welding machine, laser cold welding machine, laser argon welding machine, laser welding equipment, etc.
Laser welding uses high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation diffuses into the material through thermal conduction, and the material melts to form a specific molten pool. It is a new type of welding method, mainly used for welding thin-walled materials and precision parts. It can achieve high aspect ratio, small weld width, small heat affected zone spot welding, butt welding, seam welding, sealing welding, etc. Small deformation, fast welding speed, smooth and beautiful welding seam, no need to handle or simple processing after welding, high welding seam quality, no porosity, precise control, small focus, high positioning accuracy, and easy to realize automation.
Which industries are suitable for the use of laser welding machines
Products with welding requirements
Products that require welding seams are welded with laser welding equipment, which not only has small weld seams, but also does not require solder.
Highly automated products
In this case, the laser welding equipment can be manually programmed for welding, 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 laser welding equipment is easy to install. For example, when laser light passes through an electromagnetic field, the beam will not be deflected. The laser can be welded in vacuum, air and certain gas environments, and can pass through glass or materials that are transparent to the beam to stop welding.
Some inaccessible parts require laser welding equipment
It can weld hard-to-reach parts and realize non-contact remote welding with high sensitivity. Especially in recent years, under the condition that YAG laser and fiber laser technology are very mature, laser welding technology has achieved more general promotion and application.
