YAG laser can be used for welding:
Mainly based on the following key reasons: YAG laser welding technology is a fusion welding technology, which uses laser beam as energy and achieves welding by impacting the weldment joint with the laser beam. Secondly, YAG laser can concentrate high energy in a very small spot area. This enables the local area to be heated to high temperature in a short time during welding to achieve melting and connection of materials. For example, when welding delicate metal parts, the high concentration of energy can accurately control the welding position and depth to avoid unnecessary thermal effects on the surrounding areas.
Working principle of YAG laser welding machine
Use high-energy laser pulses to locally heat the material in a small area, and the energy of laser radiation diffuses to the inside of the material through heat conduction, melting the material to form a specific molten pool. It is a new type of welding method, mainly for the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, lap welding, sealing welding, etc. It has high aspect ratio, small weld width, small heat-affected zone, small deformation, fast welding speed, smooth and beautiful weld, no need for treatment or only simple treatment after welding, high weld quality, no pores, precise control, small focusing spot, high positioning accuracy, and easy automation.
Advantages of YAG laser welding machine
· It has the advantages of extremely small spot, high energy density, and short welding time, so as to control welding distortion and thermal effects to the extreme.
· Because it is non-contact welding, no pressure is applied to the processed object, which can avoid deformation and scratches.
· Because it is non-contact processing, maintenance is very simple.
· There is no need to consider the conductivity and circuit of the processed object.
· Welding can be performed in the atmosphere, gas, and vacuum.
· The laser or the workpiece can be moved independently during welding, and multi-point simultaneous or time-differentiated welding can be achieved, so it is easy to realize automation, with the advantages of low cost and small footprint.
YAG laser welding has a wide range of applications, and the following are some common fields:
Electronics industry: used for welding microelectronic components, such as the connection between chips and circuit boards. For example, precision welding inside electronic products such as mobile phones and computers. Medical equipment: welding of fine medical equipment components, such as surgical instruments, micro probes, etc. Mold manufacturing: repair and strengthen welding of molds to extend the service life of molds. Hardware products: welding of small hardware parts, such as hinges, locks, jewelry, etc.
