Distortion Control Calculator
Calculate pre-setting angles and control methods to minimize weld distortion.
Distortion Control Methods
| Method | Effectiveness | Application |
|---|---|---|
| Pre-Setting | High | Butt joints, T-joints |
| Backstep Welding | Medium | Long seams |
| Balanced Welding | High | Double-sided joints |
| Mechanical Restraint | High | All joint types |
| Intermittent Welding | Medium | Non-critical joints |
Understanding Distortion Control
Types of Weld Distortion
- Angular Distortion: Rotation about weld axis due to asymmetric shrinkage
- Longitudinal Shrinkage: Shortening along weld length
- Transverse Shrinkage: Contraction perpendicular to weld
- Bowing: Curvature along plate length
Prevention Strategies
- Design: Minimize weld size, use symmetric joints, avoid over-welding
- Sequence: Balance welds, use backstep or skip methods
- Technique: Lower heat input, faster travel speed
- Restraint: Fixtures, strong-backs, tack welds
