Q: Common problems and countermeasures during DC01 stamping?
A: Problems: Springback, cracking, surface scratches; Countermeasures: Optimize die clearance, control stamping speed, apply surface coating for protection.
Q: Key parameters for DC01 welding?
A: Use low-hydrogen electrodes for arc welding, with moderate current to prevent deformation; for resistance welding, strictly control pressure and energizing time to avoid incomplete welds.
Q: How to prevent rust on DC01?
A: Short-term use of rust-preventive paper/oil; long-term use can be electrophoresis, spraying, galvanizing/aluminized zinc plating, etc.
Q: Recommended bending radius for DC01?
A: Inner bending radius ≥ 0.5t (t is plate thickness) to avoid cracking.
Q: What is the purpose of annealing DC01?
A: Eliminate cold rolling work hardening, restore plasticity, and reduce the difficulty of subsequent forming.
