Weld Sequence Planner
Get optimal welding sequence recommendations for distortion control.
Sequence Methods
| Method | Best For | Effectiveness |
|---|---|---|
| Progressive | Short welds (<300mm) | Low |
| Backstep | Medium welds (300-1000mm) | Medium |
| Skip/Block | Long welds (>1000mm) | High |
| Balanced | Double-sided joints | High |
| Cascade | Multi-pass, thick sections | High |
Welding Sequence Principles
Why Sequence Matters
- Distortion Control: Proper sequence balances shrinkage forces
- Residual Stress: Sequence affects stress distribution and magnitude
- Weld Quality: Reduces risk of cracking and defects
- Efficiency: Optimizes welder positioning and travel
Key Principles
- Work from center out: Allows shrinkage to distribute evenly
- Balance heat input: Alternate sides on double-sided joints
- Weld to freedom: Allow parts to move toward less restrained areas
- Complete one joint before adjacent: Avoid locking in stresses
