Engineering Precision for Extreme Conditions
Key Technical Challenges & Solutions
- Unidirectional Dual-Arm Load Challenge
– Problem: Both lamp arms extend in the same direction, creating unprecedented torsional stress on the pole structure.
– Solution:
– Reinforced internal steel spine running through the entire pole
– Computer-modeled load distribution to prevent deformation
– Used high-grade aluminum alloy 6061-T6 for optimal strength-to-weight ratio
- Micro-Welding Precision
– Problem:
– Arm connection points require exceptionally small welds (50% smaller than conventional poles)
– Higher risk of weak joints due to reduced material fusion
– Solution:
– Laser-guided TIG welding by certified master welders
– Post-weld X-ray inspection of every critical joint
– Special heat-sink jigs to prevent warping during welding
