# Industrial Specification: Wire Feed System

## 1. Technical Definition
A system that continuously supplies welding wire to the welding torch at a controlled rate during robotic welding operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15 m/min wire feed speed, 0.2-0.8 MPa drive roller pressure**. Failure boundary: **Wire feed speed drops below 0.3 m/min or exceeds 16 m/min, drive roller pressure exceeds 1.0 MPa**, Mechanism: **Coulomb friction limit between drive rollers and welding wire (μ=0.15-0.25) causing slip, or plastic deformation of wire at &gt;350 MPa compressive stress**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
