What material does laser weld function weld, can weld much thick, suit what profession?
With the advent of laser welding machines, there is an option to buy welding machines, but it also brings more problems. For laser welding machine, we may stay in the old welding process, so in the selection of welding machine, old welding machine and laser welding machine always do not know how to choose. The reason why people are so hesitant is that they don't know much about laser welding machines. Some people use laser welders to ask "what is a laser welder? Which products can be welded laser welding machine? What are the problems in the application industry of laser welding machine?
Laser welding USES high-energy laser pulses to locally heat the material in a small area. The energy radiated by the laser travels through the heat into the material, causing it to melt into a specific pool. It is a new type of welding method, mainly used for welding thin-wall material precision parts, can achieve spot welding butt welding overlapped seal welding, welding width is small, heat affected area is small deformation, welding speed is fast, weld flat, welding quality is high, precision can be precisely controlled, positioning precision is high, and automation is easy. Laser welding machine is often 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 in many industrial technologies are unable to meet the special requirements of materials, the advantages of laser welding machine is low bonding strength, thermal impact zone wide, especially in many industries has gradually replaced the traditional welding methods.
Laser welding machine industry application as follows: bathroom industry: water pipe joint, tee, valve, shower welding. Glasses industry: stainless steel, titanium alloy and other materials buckle, precision welding frame position. Hardware industry: impeller, kettle, handle and other complex stamping parts, casting welding. Automobile industry: gasket of engine cylinder head, seal welding of hydraulic tappet, spark plug welding, filter welding and other medical industry: welding of stainless steel seals, medical appliances, medical equipment, structural parts. Electronic industry: solid state relay seal welding, connector welding, MP3 and other metal shell and structural parts. Welding of motor shell and wire, optical fiber connector connector and other household hardware: kitchen utensils, stainless steel door handle, electronic components, sensors, clocks, precision machinery, communications, crafts and other industries, automotive hydraulic treads and other high-strength products welding products.
Almost all of these industries use laser welding machines. The advantages of laser welding machine are energy concentration, no pollution, small solder joint, wide range of weldable materials, high applicability, high efficiency and high speed welding. The following requirements also apply to laser welding.
1. Products with requirements for welding seams that need to be welded shall be welded by laser welding, which is not only small in size, but also does not need to be welded.
2. Highly automated products in this case, the laser welding equipment can be manually programmed and the path is automatic.
3. Welding of the product at room temperature or under special conditions can be stopped at room temperature or under special conditions. Laser welding equipment is simple to install. For example, if a laser passes through an electromagnetic field, the beam does not move; The laser can be welded in the vacuum of air and in a gaseous environment, and can be welded through glass or transparent to a beam.
4. Some parts that cannot be touched need laser welding equipment. It can weld parts that are difficult to access, and realize non-contact long-distance welding with high sensitivity. Especially in recent years, YAG laser processing technology adopts optical fiber transmission technology, which makes laser welding technology more popular and applied.
