Why choose our Automatic Laser Welding Machine for Core Drill Bit?

Technical Core: Precise Thermal Management

Laser welding utilizes a high-energy-density beam to achieve micro-zone melting and bonding of materials.

• Highly Concentrated Heat Input: Energy acts precisely on the weld seam, minimizing thermal impact on surrounding materials.

• Extremely Small Thermal Damage Zone: The total heat-affected width is only about 2mm (approximately 10%-20% of high-frequency welding), effectively protecting the stability of diamonds in the segment. The overall segment temperature during welding remains below 300°C.

• Metallurgical Bond Formation: Achieves deep fusion between materials, laying the foundation for high strength.

Efficiency Revolution: Shorter Cycles, Simplified Process

Laser welding delivers significant improvements in production efficiency:

• Fast Welding Speed: Welding speed ranges from 100-2000mm/min, adaptable to different process requirements.

• Dramatically Shortened Cycle Time: Taking a 24mm long segment as an example, laser welding takes about 2 seconds, requires no cooling wait time, and allows for immediate handling. This reduces the overall production cycle by more than half compared to traditional methods.

• Reduced Comprehensive Energy Consumption: The equipment's maximum power is 3kW, with a typical welding power of about 1700W, significantly lower than high-frequency welding (typically ≥5kW).

Equipment Advantages: Quantifiably Defining High-Performance Manufacturing Standards

This Automatic Laser Welding Machine is designed specifically for diamond core drill bits/ thin-wall drills. Its advantages are demonstrated through verifiable performance and functionality:

1. Significantly Enhanced Welding Strength

   • Weld joint torque strength can reach 22-25N, representing an increase of over 22% compared to traditional high-frequency welding (approx. 18N).

   • The high-strength bond ensures the segment is less prone to falling off or deforming during prolonged dry or wet drilling.

2. Excellent Process Consistency and Flexibility

   • Equipped with automatic weld seam and focal position locating, featuring an automatic weld correction function capable of correcting matrix deviations of ±0.5mm.

   • Achieves fast, direct welding of segments through a four-axis CNC motion optical system.

   • A flexible and reliable clamping system supports matrices with diameters from 25-400mm (segmented bits) and 8-60mm (crown bits), minimizing setup time.

3. Lower Comprehensive Cost of Use

   • The welding process requires no silver or copper solder tabs, directly saving expensive brazing material costs.

   • Lower energy consumption and higher yield rates contribute to long-term production cost optimization.

Forward-Looking Expansion: Built for High-Performance Segments
