Copper is one of the earliest metals used by humans and has many excellent characteristics and functions: good thermal and electrical conductivity, excellent plasticity, easy hot pressing and cold pressure processing, etc. Currently, among the non-ferrous metals consumed by domestic industry, copper ranks second, second only to aluminum, and is widely used in the construction industry, electrical, machinery manufacturing and other industries.

★ SUMMI Xinhe Technology focuses on copper welding ★

The conventional copper welding in the market mainly optimizes the welding quality by reducing the laser wavelength and improving the material absorption rate, such as using blue light, infrared blue light composite, green light and other lasers. However, these lasers have short life and high price compared with conventional infrared band lasers.

To this end, SUMMUS Xinhe Technology has launched laser welding equipment using "infrared continuous fiber laser", which can be freely edited to realize any form of light spot. At the same time, combined with the SUMMUS process control system, it can flexibly and independently control the luminous power, frequency and duty cycle of each pixel light spot. It can customize exclusive technical solutions for welding high-reflection materials such as copper to meet high-quality copper welding needs.

SUMMUS Application Case 1: Copper Coil Welding

In the past, coil processing was generally in the form of soldering and hydraulic pressure, but these methods were not strong and conductive, which could not meet the needs of high-standard industries. And SUMMUS Xinhe laser welding has become a better processing method choice due to its advantages of high efficiency, no consumables, and strong conductivity.

Welding skills: 1. When welding, the angle of the welding joint is tilted to prevent long-term reflections from damaging the laser.

2. The laser uses a small core diameter, and the energy density is relatively concentrated, making it easy to achieve the absorption value of copper.

3. Swing welding can improve the surface quality of welding.

Application industries: power electronics, aerospace

SUMMUS Application Case 2: Copper plate welding

Red copper plate welding requires a smooth and flat surface, no explosion points and bumps, no thermal influence on the back, and no deformation after welding. SUMMUS Xinhe laser welding has the excellent characteristics of high energy density, high welding efficiency, small heat affected zone, and high degree of automation, making it suitable for the welding of red copper materials.

Welding skills: using circular segmented welding to increase tension, control deformation, fast low swing and high density, control the bottom without welding through, and control the surface flatness with small spacing.

Application industry: construction industry, electrical industry

SUMMUS Application Case 3: Red Copper Block Welding

Small pieces of copper block welding require good sealing performance after welding, and the weld does not crack. The melting of materials during welding is the key to welding. If the temperature is not well controlled, it will lead to uneven melting of materials, thus affecting the sealing of welding.

Welding skills:1.When welding, the angle of the welding joint is tilted to prevent long-term retroreflective damage to the laser.

2.The power of the laser must reach the absorption value of copper to prevent light from being reflected.

3.The laser adopts a small core diameter, the energy density is relatively concentrated, and the temperature is stable.
