2.1copper welding

Copper has high thermal conductivity, heat is easy to spread rapidly during welding, and the heat affected zone is enlarged，Cause deformation of the welded parts.Also, copper is highly reflective，existAbsorption Rate of Copper to Laser at Room Temperatureless than5%The molten pool is unstable during processing，It is prone to spatter, forming a large number of pores, which seriously affects the welding quality and airtightness.

chooseSupreme SV55proType laser welding machine for copper welding, accurate and stableLaser through the beam of light shaping and multi-swing galvanometer welding head, using the beam of light to stir the molten pool, expand the keyhole, improve the stability of the molten pool, reduce the splash and micro-pores after welding, and effectively improve the welding airtightness，Solve the difficulty of gas tightness in copper welding.

2.2Aluminum welding

The difficulty of aluminum alloy welding lies in itsThe surface is prone to a refractory oxide film，High thermal conductivity, large coefficient of expansion, easy to heatproducedeformationAs a highly reflective metal material,High laser reflectivityup to70%Above, when weldingEasy to produce pores, hot cracks, etcThis phenomenon affects the welding effect. 

chooseSUMMUS SV55Type laser welding machine for easy welding1-7Aluminum alloy,ADC12Aluminum and other aluminum materials. Xinhe LaserRing light spot technology through a unique optical path design, the central light spot provides a high energy density to produce a keyhole, forming penetration, the outer ring light spot can stabilize the keyhole and molten pool, reduce the fluctuation of molten pool, reduce the probability of porosity, improve the uniformity and stability of welding.
