The working principle and industry selection of carbon dioxide co2 laser marking machine

With the emergence of laser welding machines, there is one more choice for everyone when buying welding machines, but it also brings more problems. For laser welding machines, everyone may stay in the old-fashioned welding process, so that when purchasing a welding machine, you are always wandering between the old-fashioned welding machine and the laser welding machine and do not know how to choose.

Laser Welding Exercise

And the reason why people are so hesitant is because they don't know enough about laser welding machines, and some people will ask 'What is a laser welding machine? Welding machine? What products can laser welding machine weld? What are the application industries of laser welding machine?' and so on.

Laser welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of the laser radiation diffuses into the material through heat conduction, and the material is melted and formed. specific melt pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts, and can realize spot welding, butt welding, stitch welding, sealing welding, etc. The deformation is small, the welding speed is fast, the welding seam is flat and beautiful, no treatment or simple treatment is required after welding, the welding seam quality is high, it can be precisely controlled, the positioning accuracy is high, and it is easy to realize automation.

Laser welding

Laser welding machine is also often called fiber laser welding machine, energy negative feedback laser welding machine, pulse laser welding machine, YAG laser welding machine and other 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, and laser welding machines are widely used due to their low bonding strength and wide heat-affected zone. In many industries, the traditional welding method is gradually replaced.

The industry application of laser welding machine involves the following industries:

Laser welding samples

Sanitary industry: water pipe joints, reducing joints, tee, valves , shower welding;

Medical industry: medical equipment, medical equipment stainless steel seals, welding of structural parts;

Hardware industry: impeller, kettle, handle, etc., welding of complex stamping parts, casting parts; Precision welding at equal positions;

Automotive industry: engine cylinder gasket, hydraulic tappet seal welding, spark plug welding, filter welding, etc.;

< /p>

Electronic industry: solid state relay sealing and breaking welding, welding of connector connectors, welding of metal casings and structural parts such as mobile phones and MP3. Welding of motor housings and cables, optical fiber connectors, etc.;

Household hardware, kitchenware, bathroom, stainless steel door handles, electronic components, sensors, clocks, precision Machinery, communications, handicrafts and other industries, automotive hydraulic tappets and other high-strength industries;

Almost all of these industries can use laser welding equipment, laser welding The advantages are energy concentration, no pollution, small solder joints, wide range of weldable materials, high applicability, high efficiency and high speed of welding, etc. At the same time, products with the following requirements are also suitable for laser welding.

Automatic laser welding machine

1. Products with high automation: in this case, the laser welding equipment can be manually programmed for welding, and the path is automatic.

2. Products that have requirements for welds: products that have requirements for welds are welded by laser welding equipment, which not only has small welds, but also does not require solder.

3. Some inaccessible parts need to use laser welding equipment: it can weld inaccessible parts, and implement non-contact remote welding with great sensitivity. Especially in recent years, optical fiber transmission technology has been adopted in laser processing technology, which has made laser welding technology more widely implemented and applied.
