For Better Welding Quality

Laser welding, or Laser Beam Welding (LBW), employs a focused laser beam for melting and fusing metal components. This process allows for high-speed welding of thin materials and produces narrow, deep welds for thicker materials, ensuring precision in joining metal parts.

 

LBW is a versatile fusion welding method applicable to various materials, including carbon steels, HSLA steels, stainless steel, aluminum, and titanium. While it excels in high-quality welds, special attention is needed for high-carbon steels due to potential cracking from rapid cooling. The use of high-power gas lasers, particularly suitable for high-volume applications, makes LBW a prevalent choice in the automotive industry.

 

In fiber lasers, the main medium is the optical fiber itself. They are capable of power up to 50 kW and are increasingly being used for robotic industrial welding.

Laser Welding has many advantages over traditional welding methods:

1. Precision and Control: Laser welding offers precise control over heat input and weld placement.
2. Efficiency: Rapid heating and cooling process reduces overall cycle time.
3. Strength and Versatility: High temperatures achieved by lasers result in strong and durable welds, suitable for a wide range of materials and thicknesses.
4. Adaptability and Automation: The process is easily automated and compatible with robotic machinery.
5. Safety: Unlike some methods, laser welding doesn’t generate x-rays.
6. Clean and Precise: Lower porosity, less spatter, and low thermal impact contribute to clean and precise welds.
7. Deep and Narrow Welds: Laser welding can achieve deep and narrow welds.
8. Electrode-Free: The process doesn’t require an electrode.
