Small Laser Welding Machine

Principle of Small Laser Welding Machine:

Laser welding, that is, using high energy laser pulses to heat the material locally in a small area. The energy of the laser radiation spreads to the inner part of the material through heat conduction, and then melts the material to form a specific molten bath. It is a new type of welding method. It is mainly designed for the welding of thin wall materials and precision parts. It can realize spot welding, butt welding, superposition welding, sealing welding and so on. It has characteristics like large depth-to-width ratio, small welding width, small heat affected zone, small deformation, fast welding speed, smooth and beautiful weld joints, treatment free or simple treatment after welding, high quality of the weld joints, no gas hole, precision control, small focusing spot, high positioning accuracy and automation is easy to realize.

Advantages of Small Laser Welding Machine:


1. Fast speed, large depth and small deformation.
2. Welding can be conducted at room temperature or under special conditions, the installation of welding equipment is simple. For example, the beam won’t shift when a laser passes through an electromagnetic field; the laser can conduct welding in vacuum, air, and a certain gas environment, it can weld materials directly through glass or transparent material.
3. It can weld refractory materials such as titanium and quartz, and anisotropic material, the welding effect is good.
4. After laser focusing, the power density is high. When welding high power devices, the depth-to-width ratio can reach 5:1, up to 10:1.
5. Micro-welding can be carried out. Small spot appears when laser beam is focused, the spot can be precisely positioned. Micro-welding can be applied to group welding of micro and small workpiece in large scale automatic production.
6. It can weld inaccessible parts and carry out non-contact remote welding. It has great flexibility.  In recent years, fiber-optic transmission technology has been added to YAG laser processing technology, which makes laser welding technology been widely promoted and applied.
7. Laser beam is easy to realize beam split in time and space, and can carry out multibeam simultaneous processing and multstation processing, which provides conditions for more precise welding.

Range of Small Laser Welder Application:


Small laser welder machine is widely used in the welding of jewelry, battery nickel belt, integrated circuit lead, clock wire, kinescope, electronic gun assembly, sensor, tungsten wire, high power diode (triode), aluminum alloy, notebook computer shell, cell phone battery, mould, electrical accessories, filter, lubricating nipple, stainless steel products, golf head, zinc alloy handicraft and so on.

Weldable figures are dots, straight lines, circles, squares or any plane graphics drawn by AUTOCAD software.
