# The Wind Line
|

|
|
|
||
|
|
## Premise
|
||
|
|
At 8 m/s (17.9 mph), argon shielding gas collapses around a TIG/MIG arc. Oxygen intrusion begins within 0.3 seconds. The weld pool oxidizes. The joint fails.

## Source
|
||
|
|
- **Standard**: AWS D1.1 Structural Welding Code — Steel
|
||
|
|
- **Section**: 5.2 Environmental Controls
|
||
|
|
- **Threshold**: 8 m/s maximum wind velocity for gas-shielded processes
|
||
|
|
|
||
|
|
## The Math
|
||
|
|
```
|
||
|
|
Critical Velocity (v_c) = 8 m/s
|
||
|
|
Shielding Integrity = 1 - (v / v_c)^2
|
||
|
|
When v ≥ v_c: Integrity → 0
|
||
|
|
```
