200WJewelry laser welding machine:Black and green

200W jewelry laser welding machine allows precious metals and many other alloys to be joined together,without the use of solder or torches,Laser welds are strong even in areas ,which are difficult to access with traditional joining technologies.



Laser welding is a new type of welding method, and it is also one of the important aspects of the application of laser material processing technology. Laser welding is mainly aimed at the welding of thin-walled materials and precision parts. The welding process belongs to the heat conduction type, that is, the surface heat is heated by laser radiation. The surface heat is diffused internally through heat transfer, and the workpiece is melted by controlling the parameters such as laser pulse width, energy, peak power and repetition frequency. 

To form a specific molten pool. 

It can realize spot welding, butt welding, stack welding, seal welding, etc., with high aspect ratio, small weld width, small HAZ, small deformation, fast welding speed, smooth and beautiful weld, no treatment or simple treatment after welding, high weld quality, no air hole, accurate control, small focus spot, high positioning accuracy, easy to realize automation.

Application Industry and scope

Widely used in gold and silver jewelry, stainless steel, titanium alloy, precision casting products welding, hole mending, spot welding sand holes, mosaic parts and. 

The welding of the claw foot.

its main technical features

The utility model adopts imported ceramic focusing cavity with high reflectivity, strong energy and long service life. 

Equipped with special water cooler, it can meet the requirements of long-time and high-power welding. 

The utility model has the advantages of high speed, high efficiency, large depth, small deformation, small heat affected area, high welding quality, no pollution of solder joint, high efficiency and environmental protection. 

The cross cursor indicates, and the high-speed liquid crystal light valve is used to block the light automatically, and the protective gas is output synchronously with the laser to ensure the beauty of the solder joint. 

It doesn't oxidize and change color. 

No noise in processing and no pollution to the environment.
