In recent years, the application of stainless steel sheet is more and more extensive, in mold repair, hardware and crafts spot welding, electronic components, stainless steel sanitary appliances, faucets, mobile phone shell studs, stainless steel elbow joints, clocks, precision mechanical products, etc. Therefore, the packaging and welding of ultra-thin stainless steel products become very important. Then how thick can the hand-held laser welding machine weld (metal laser welding machine)!
The traditional welding method is difficult to ensure the welding forming quality of sheet metal, and laser welding has the advantages that the traditional welding can not compare, which can effectively reduce the welding defects. In the laser welding industry, there are many manufacturers that use laser to weld stainless steel parts, the welding effect of laser welding machine is also very good, and laser welding is also a good choice for stainless steel materials.
How thick is the hand-held laser welding machine?
The depth of laser welding is related to the properties of materials, including the thickness of materials. It is impossible to select the same parameters for welding carbon steel and titanium materials.
The problem of how thick the laser welding machine can weld is mainly around the steel plates with different thickness of 1mm, 2mm, 3mm, 4mm and 5mm and the welding machines with different power of 300W, 600W and 1000W.
1. YAG laser welding machine
The welding effect of 3mm inner thickness is the best.
2. 300W laser welding machine
The thickness of overlay welding is not more than 1.5mm, of course, sometimes the parameters set for the slightly thicker points can also be welded through the strength and thermal deformation are generally unacceptable.
3. 600W laser welding machine
It can meet the requirements of 1.5mm steel plate with thickness less than 1 mm and penetration less than 1 mm for kitchen, household appliances and high-speed stainless steel laser welding.
4. 1000W laser welder
2mm thick stainless steel plate, required to be fully welded, the finer the weld, the better. It is recommended to use 1000W fiber laser for welding, the speed can be more than 1 m / min, 500W can also be used but the speed is slow.
Application range of fiber laser welding
Bathroom industry: three dimensional space curve welding of water pipe joint, reducer joint, tee joint, valve and sprinkler head. Battery industry: laser welding of lithium battery, battery pack and electrode. Glasses industry: stainless steel, titanium alloy and other materials of glasses buckle, outer frame and other positions of precision welding. Hardware industry: impeller, kettle, handle, etc., welding of complex stamping parts and casting parts.
Laser welding belongs to non-contact welding, the working process does not need to be pressurized. Its working principle is to irradiate the laser beam with high energy intensity directly on the surface of the material. Through the interaction between the laser and the material, the material is melted internally, then cooled and crystallized to form a weld. leapion
