laser cleaning machine 1000w rust is an efficient and precise welding method using high energy density laser beam as a heat source.
Laser welding is one of the important applications of laser material processing technology.
Is mainly used for welding thin wall material and low speed in the 1970 s, the welding process is thermal conduction,
i.e. the laser radiation heating surface, the surface heat to the internal diffusion through heat conduction,
by controlling the width of laser pulse, energy, peak power and repeating frequency, parameters such as melting of components,
to form specific molten pool. Because of its unique advantages, it has been successfully used in precision welding of micro and small parts.
Why laser welding? Because laser welding has the following advantages:
1. High energy density, low heat input, small thermal deformation, narrow melting zone and heat affected zone and large melting depth;
2, the cooling speed is high and the microstructure of the micro weld is obtained, and the joint performance is good;
3, compared with the contact welding, laser welding without electrodes, so reduce the time and cost;
4, do not need the vacuum atmosphere of electron beam welding, and the protective gas and pressure are optional,
the shape of the welder is not affected by electromagnetic, do not produce X-ray;
5, can be closed transparent object internal metal material welding;
6, laser optical fiber can be used for long-distance transmission, so as to make the process of good adaptability,
with the computer and manipulator, can realize the automation and precision control of the welding process
