In current industrial production, the consumption of red copper is second only to aluminum. Red copper in the building. Electrical. Machinery manufacturing and other fields have been widely used. Copper has excellent thermal conductivity, electrical conductivity, plasticity, cold pressing and other processes, and is widely used in various industries.

Problems easy to occur when welding red copper:

(1) Melting difficulty and variability: due to the large heat conduction system coefficient of red copper, the heat conduction rate is very high in the welding process, and the heat affected zone of the whole weld is large, which makes the material difficult to combine; In addition, because copper has a large coefficient of linear expansion, in the welding process, the clamping force of the fixture is not appropriate, will cause the deformation of the material.

(2) Easy to produce cavity: in copper welding, another major problem is the porosity, especially in deep penetration welding. There are two reasons for the formation of pores, one is the diffusion pores formed by the dissolution of hydrogen in copper, the other is the reaction pores formed by hydrogenation reduction.

Solution:

At room temperature, the absorption rate of copper is about 5%. When it is close to the melting point, its absorption rate can reach 20%. Therefore, in order to achieve laser deep melting of copper, it is necessary to increase the laser power density.

Using high power laser and galvanometer welding joint, using the beam to stir the molten pool, expand the keyhole, improve the stability of the molten pool, reduce spatter, reduce the micro pores after welding.
