Economy Single Purpose Hi-Lo Welding Gauge – PTA WG01A

The Economy Single Purpose Hi-Lo Welding Gauge provides a simple and reliable way to measure internal pipe misalignment during weld preparation and inspection. Pipe fitters and welding inspectors use this gauge to check internal Hi-Lo alignment after fit-up to ensure it stays within code requirements. This is especially useful when working with pipe joints where the back side of the weld is difficult or impossible to access.

The gauge helps confirm that pipe sections align correctly before welding begins. By checking internal alignment early, welders can correct fit-up issues before they lead to welding defects. As a result, the tool helps reduce the risk of radiographic rejects and costly rework.

A tapered measuring section allows the gauge to measure root gaps accurately. This helps verify that the joint preparation follows the required Welding Procedure Specification (WPS). Proper root gap measurement improves weld penetration and helps prevent defects such as lack of fusion.

The Economy Hi-Lo Gauge uses a compact and lightweight design, making it easy to carry in a pocket or tool pouch. Because of its small size, inspectors can quickly check pipe alignment during fabrication or installation work. This helps maintain efficiency on both workshop and site projects.

Manufacturers produce the gauge from high-quality steel, providing strength and durability for regular use. The surface markings are laser engraved, which helps prevent wear and ensures measurements remain clear and easy to read over time.

This welding gauge works well in a variety of industries. It is widely used for boiler fabrication, shipbuilding, bridge construction, pressure vessel manufacturing, and oil pipeline welding inspection. Because of its simplicity and accuracy, it remains a practical tool for routine pipe welding inspection.

The gauge also includes a protective pouch, which helps protect the tool during storage and transport.
