# Industrial Specification: Electrode Holder

## 1. Technical Definition
A mechanical clamping device that securely holds and positions the welding electrode within a welding head assembly.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Clamping force: 150-450 N, Temperature: -20°C to 200°C, Electrode diameter: 1.6-6.0 mm**. Failure boundary: **Clamping force drops below 100 N, Temperature exceeds 250°C, Contact resistance rises above 0.5 mΩ**, Mechanism: **Thermal expansion mismatch between copper alloy jaws and steel body causes loss of clamping force at 250°C due to differential CTE (17×10⁻⁶/K vs 12×10⁻⁶/K)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Arc blow deflection exceeding 15° from electrode axis | 8 | Asymmetric electrode wear causing elliptical arc pattern | Integrate magnetic field compensation coils with 50-200 A·turns adjustment |
| Electrode slippage due to jaw surface contamination exceeding 5 μm Ra roughness | 8 | Inconsistent arc initiation with &gt;50 ms delay variance | Implement diamond-like carbon coating (DLC) with hardness &gt;20 GPa on jaw surfaces |
