Why Weldhit HFMI Outperforms Alternatives
| Treatment Method | Fatigue Extension | Treatment Speed | Operator Dependence | Weldhit HFMI Advantage |
|---|---|---|---|---|
| As-Welded Joint | Baseline (1x) | N/A | High | Severe tensile stress present |
| TIG Dressing | 1.3x – 1.8x | Slow | Very High | ✓ 4x Faster execution speed |
| Needle Peening | 1.2x – 1.5x | Moderate | High | ✓ Deeper compressive layer (~2mm) |
| Burr Grinding | 1.5x – 2.0x | Very Slow | High | ✓ Smooths geometry + Induces compression |
| Weldhit HFMI | 3x – 10x | Fast (~100 Hz) | Low (Repeatable) | ★ Gold Standard in IIW Guidelines |
How HFMI Neutralizes Weld Failure
Notch Geometry Smoothing
High-frequency impacts smooth the sharp transition profile at the weld toe, removing microscopic undercut flaws and drastically reducing local stress concentration factors.
Deep Compressive Stress Injection
HFMI cold-works the steel surface, replacing damaging tensile residual stresses from welding cooling with a deep layer (up to 2 mm) of beneficial compressive stress.
Surface Grain Strain Hardening
The intense cyclic impacts strain-harden the near-surface microstructure, raising local yield strength and preventing micro-crack initiation during dynamic cyclic loading.
