HI-LO Welding Gauge

Hi-Lo Welding Gauge – Precision and Versatility in One Tool

Designed for professional welders and fabricators, the Hi-Lo Welding Gauge offers multipurpose functionality, making it an essential tool for accurate dimensional verification. Both standard (imperial) and metric units are conveniently displayed directly on the gauge for quick reference during inspections.

Three Distinct Scales for Accurate Measurements

This precision instrument features three specialized scales to cover a wide range of welding checks. The Material Thickness Gauge measures in sixteenths, the Internal Alignment Scale is read in 3/32nds, and the Scribe Line Scales are evaluated in sixteenths. These options allow for precise fit-up and verification work across multiple welding applications.

The Hi‑Lo Welding Gauge is widely used by welding inspectors, fabrication quality control teams, and structural steel erectors to measure weld reinforcement, undercut, and joint fit‑up conditions. Welding gauges help verify that welds meet specified dimensional tolerances and code criteria, and industry resources on welding inspection note that dimensional measurements support quality assurance in structural and pressure‑retained weld joints.

Professionals value the Hi‑Lo gauge for its simple, rugged design, clear graduations, and ability to check multiple weld attributes rapidly during shop or field inspections. Compared with improvised measuring tools, a dedicated welding gauge provides repeatable checks that improve adherence to welding codes and reduce rework during fabrication and maintenance quality control workflows.

Applications of the Hi-Lo Gauge

• Check internal misalignment after fit-up
• Measure material thickness after fit-up
• Verify a 37-1/2 degree bevel angle
• Inspect fit-up gap after fit-up
• Measure fillet weld leg length
• Assess buttweld reinforcement

Package Includes

1. UP 2131 Red and White Storage Box
2. OP-1503 Category 1 Insert
3. ULN 234 – Protective Plastic Bubble Wrap Bag
