# Industrial Specification: Welding Head

## 1. Technical Definition
The component of an electric motor rotor lamination stacking and welding machine that performs the actual welding operation on rotor laminations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 MPa welding pressure, 150-250 A welding current, 15-25 V arc voltage**. Failure boundary: **Welding pressure exceeds 1.5 MPa causing electrode deformation, welding current exceeds 300 A causing electrode tip melting, arc voltage drops below 12 V causing unstable arc formation**, Mechanism: **Electrode tip thermal fatigue from cyclic heating (800-1200°C) and cooling during 0.5-2.0 second weld cycles, electrode wear from material transfer during welding (0.01-0.05 mm per 1000 welds), arc instability from magnetic blow effect in rotor lamination magnetic fields**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Electrode misalignment exceeding 0.1 mm perpendicular to lamination surface | 8 | Uneven weld penetration causing lamination separation under 50 N tensile load | Precision alignment mechanism with 0.01 mm resolution laser positioning and real-time force feedback control |
| Cooling water flow rate dropping below 2.0 L/min at 20°C inlet temperature | 8 | Electrode temperature exceeding 400°C causing copper annealing and increased contact resistance | Dual redundant cooling circuits with flow sensors (0.5 L/min resolution) and automatic shutdown at 1.5 L/min threshold |
