Copper is Indeed One of the Most Difficult Materials to Weld
Some Difficulties in Welding Copper and Brass Materials by Traditional Welding Methods, Like Electro Welding,TIG Welding,Gas Shielded Welding.
- It is the effect of high thermal conductivity, the thermal conductivity of copper is 7 to 11 times greater than that of carbon steel and stainless steel. Traditional welding methods and parameters make it difficult to melt the copper, and the filler metal and the base material do not fuse well.
- The welded joint has a high tendency to thermal cracking. When welding, the copper in the molten pool and the impurities in it form a low melting point eutectic. It makes copper and copper alloys have significant thermal embrittlement and then thermal cracking.
- Copper and Brass has a large coefficient of thermal expansion. The thermal expansion and contraction during the welding process is particularly obvious, so the deformation after welding is larger.
What Are the Advantages of Laser Welding Copper and Brass?
Laser Welding Machines Use High Energy Laser Beams to Melt the Surface of the Material to Achieve the Purpose of Welding. when Laser Welding Copper Materials, Although the Very High Thermal Conductivity of Copper Materials, Makes the High-energy Laser Heat Diffuse Rapidly from the Welding Head, Increasing the Laser Power Can Solve This Problem. You Can Choose a MOZLASER Laser Welding Machine with Laser Power Up to 3000w.
In Addition, MOZLASER Wire Filling Welding Feature is a Great Way to Avoid Copper Heat Transfer Problems. As the High Energy Laser Beam Quickly Melts the Wire and Fills the Weld Joints. The Wire Filling Welding Feature is Also a Good Solution for Joining Copper to Other Materials.
Finally, the Wobble Welding Function of Our Laser Welding Machine is Very Helpful for Laser Welding Copper to Overcome the Difficulties Int the Copper Welding Process. Our Tests Have Shown That by Wobbling the Beam in a Highly Dynamic Manner, the Copper Welding Process is Very Stable. Thus Reducing or Avoiding Porosity and Spattering, and Ultimately Producing a High Quality Weld Result.
