FAQ
Why Is Brass Welding More Challenging Than Ordinary Metals?
Brass is more difficult to weld due to its high reflectivity, excellent thermal conductivity, and the high volatility of zinc. During traditional welding processes, it often encounters the following challenges:
- High laser reflectivity reduces energy absorption, resulting in insufficient penetration and unstable welding performance;
- Rapid heat conduction causes heat to dissipate quickly from the welding area, reducing processing efficiency;
- Zinc evaporation during heating can lead to welding defects such as porosity and spatter;
- The weld area is prone to oxidation, affecting weld appearance and overall product quality.
The DXTECH brass laser welding machine utilizes a high-power-density laser beam, precise energy control, and intelligent welding parameter adjustment technology to effectively overcome the challenges of brass processing, delivering high-quality, stable, and reliable welding results.
