SK WGU-8M
Multi-function Welding Gauge
Model: WGU-8M
The SK Welding Gauge (WGU-8M) is a versatile stainless-steel measurement tool for inspecting various weld dimensions in fabrication and quality control. Designed to support a wide range of welding applications, this compact gauge allows welders and inspectors to quickly check fillet size, undercut depth, bevel/groove angles, and other critical weld features — helping ensure welds meet required standards for strength and quality.
Key Features & Benefits
- Multi-Function Measurement — Accurately measures fillet leg length, bead height, undercut depth, groove/bevel angle, and gap sizes with one tool.
- Durable Construction — Made from stainless steel for corrosion resistance and long service life in workshop environments.
- Easy to Read & Use — Clear scale markings on a single plane for quick, intuitive reference during inspections.
- Improves Quality Control — Supports consistent welding standards and helps identify dimensional issues early in fabrication.
- Compact & Portable — Lightweight design makes it convenient for field work or shop use.
