Gauge-W.T.P.S & C/Block – GAL #07

The GAL WTPS Gauge with Calibration Block delivers precise weld inspection with a strong focus on detecting undercut defects. It uses high-quality stainless steel, so it resists corrosion and handles tough workshop and site conditions without issue. The compact design makes it easy to carry and quick to use during inspections.

This gauge measures undercuts up to 0.010″ (0.25 mm) deep. That limit matches common requirements in American Welding Society D1.1 structural welding codes. Inspectors rely on this standard to confirm weld quality and maintain structural strength. The tool helps you spot unacceptable undercuts fast, so you can correct issues before they cause failure.

You can operate the gauge with a simple, direct method. Place it across the weld and check the gap against the measuring edge. This process gives you a clear visual result without complicated setup. It saves time and improves consistency during repeated checks.

Laser-engraved markings improve readability and durability. The scale stays sharp even after heavy use. You can read measurements clearly in low light or dirty environments, which helps reduce errors on site.

The included calibration block increases confidence in every measurement. It features a surface ground finish with a tight tolerance of 0.0005″. You can quickly verify accuracy before starting inspections, which ensures reliable results every time.

Many users pair this gauge with other weld inspection tools to cover additional measurements like fillet size and reinforcement. Together, they create a complete inspection setup.

Lightweight and pocket-sized, the WTPS Gauge fits easily into any tool kit. It works well for welders, inspectors, and quality control teams who need fast, accurate undercut measurement.
