1. Materials and Weldability: High-strength or wear-resistant steel is used, and special attention must be paid during welding:
Cold Crack Sensitivity: Low-hydrogen welding materials are required, and preheating and interpass temperatures must be strictly controlled.
Heat Affected Zone Softening: Low heat input welding processes, such as pulsed MAG welding, are necessary.
2. Fixture and Positioner Design: This is crucial for success.
Rigidity: Sufficient clamping force and structural rigidity must be provided to withstand the enormous welding stresses.
Aspect Ratio: Structural components often have many cavities; fixture design must fully consider the accessibility of the welding torch to avoid interference.
Positioning Capability: Large-tonnage, multi-axis positioners are required to achieve precise flipping and positioning of complex workpieces.
3. Process and Systems:
Robot Selection: Choose a long-arm robot from FANUC or Yaskawa to cover large workpieces.
Welding Machine Selection: Pulse welding machine, providing stable, low-splatter, high-quality welds.
Weld Tracking: Highly recommended to compensate for material handling and assembly errors.
Our Advantages: We deeply understand the process requirements and production rhythms of the construction machinery industry, and can provide customers with a complete turnkey project from workpiece analysis, fixture design, robot system selection to process debugging.
