MG-8 - Bridge Cam Gauge MG-8

Comprehensive Welding Inspection with the MG-8 Cam Type Gauge

The Techniweld MG-8 Cam Type Weld Gauge, widely known in the industry as the "Bridge Cam Gauge," is a fundamental instrument for quality assurance and control in welding fabrication. Designed to meet the rigorous demands of Certified Welding Inspectors (CWI) and industrial quality control departments, this versatile tool consolidates multiple measuring functions into a single, durable stainless steel unit. It is engineered to verify compliance with major welding codes such as AWS D1.1 and ASME Section IX by providing accurate dimensional data on weld geometry and joint preparation.

Constructed from high-grade stainless steel, the MG-8 is built to withstand the harsh environments of shipyards, pipeline construction sites, and heavy fabrication shops. The gauge features deeply etched, laser-engraved markings that resist fading and wear, ensuring that measurements remain legible even after years of frequent use. Its dual-scale design allows inspectors to read measurements in both Imperial (inches) and Metric (millimeters) units without the need for conversion charts, streamlining the inspection process and reducing the potential for calculation errors.

The MG-8 Cam Type Gauge is capable of performing six critical measurements essential for weld verification:

• Angle of Preparation: Measures the bevel angle of pipe and plate from 0° to 60°.
• Excess Weld Metal: Quantifies the height of weld reinforcement (capping size).
• Depth of Undercut: Accurately measures the depth of undercut or pitting on the base metal.
• Fillet Weld Throat Size: Determines the theoretical throat dimension of fillet welds.
• Fillet Weld Leg Length: Verifies the leg length of fillet welds.
• Misalignment (High-Low): Checks the internal or external misalignment of pipe or plate joints.

For industrial suppliers and MRO procurement specialists, stocking the MG-8 ensures you are providing your clients with the industry-standard tool for visual weld inspection. Its reliability, accuracy, and multi-functional capability make it a staple item for any toolkit destined for structural steel, piping, or pressure vessel work.
