TECHNICAL DATA SHEET (TDS) & PROCESS GUIDE Standard: AISI H13 / DIN 1.2344 / JIS SKD61
1. Chemical Composition (wt%)
| Element | C | Si | Mn | Cr | Mo | V | Fe |
|---|---|---|---|---|---|---|---|
| Specification | 0.32–0.45 | 0.80–1.20 | 0.20–0.50 | 4.75–5.50 | 1.10–1.75 | 0.80–1.20 | Balance |
2. Welding Parameters: Laser vs. TIG
⚡ Laser Welding 0.2–0.6 mm
| Preheat Temp | Room Temp – 100°C |
| Pulse Power | 120–220 A |
| Shielding Gas | Argon ≥99.99% (3–6 L/min) |
| HAZ Impact | Extremely low (<0.1 mm) |
🔥 TIG Welding 0.8–2.4 mm
| Preheat Temp | 300°C – 400°C Mandatory |
| Welding Current | 40–120 A (DCEN) |
| Shielding Gas | Argon ≥99.99% (8–12 L/min) |
| Post-Heat | Slow cooling or 500°C stress relief |
💡 Key Repair & Operation Instructions:
- Surface Preparation: Thoroughly clean oil, rust, and fatigue layer around cracks using a grinder before welding.
- Crack Prevention (TIG): H13 has high hardenability. Preheating to 300°C+ is critical for TIG welding to avoid cold cracking.
