Modern aerospace welding still relies on a fragile assumption: that critical process steps will always be executed correctly by human operators.

One of the most common failure modes of the TIG welding process occurs when backing gas is not applied to the root side of the weld. When this happens, defects may not be immediately visible, but can later lead to cracking, rework, scrap, or field failures.

These events cost manufacturers millions of dollars annually and introduce unacceptable risk in high-reliability environments.

Weld Integrity developed a patent pending process-control solution that prevents this failure mode before defects occur by ensuring that welding cannot proceed unless backing gas is confirmed as present.

Rather than relying on training, reminders, or inspections after the fact, this system enforces compliance at the point of action.

How It Works

This system integrates directly into existing TIG welding workflows.

The system monitors backing-gas presence in real time and prevents welding from occurring until required conditions are verified. No changes to the welder are required — compliance is enforced automatically.

The result is a controlled welding process that removes reliance on memory or attention for a critical quality step.
