What welding rods are suitable for DC01 welding?
A: Low-hydrogen welding rods are recommended to avoid hydrogen embrittlement during welding and prevent cracking during subsequent use.
What post-weld treatment is needed for DC01?
A: For complex components, low-temperature stress relief treatment at 180-220℃ can eliminate over 90% of residual welding stress and prevent embrittlement of the hardened zone.
What defects are prone to occur during DC01 stamping?
A: Common defects include stamping cracks and excessive springback, mostly caused by excessively fast deformation rates or improper die adjustments.
How to prevent cracks during DC01 stamping?
A: Control the deformation rate to ≤50mm/s, use 150-200℃ warm stamping to improve plasticity, and avoid local strain exceeding 25%.
How to solve excessive springback during DC01 stamping?
A: This can be solved through die compensation. A 3°-5° correction angle should be reserved in the die design to offset springback deformation after stamping.
