MG-8 - Bridge Cam Gauge MG-8

Master Your Weld Quality with the MG-8 Bridge Cam Gauge

Take the guesswork out of your welding projects with the MG-8 Cam Type Weld Gauge. Often called the "Bridge Cam," this handy pocket-sized tool is a favorite among professional welders who care about precision and passing inspection the first time. Whether you are fitting up pipe, checking your bevels, or verifying that your fillet welds meet the print specifications, the MG-8 gives you the immediate feedback you need to adjust your technique and ensure a sound, code-compliant weld.

Made from tough stainless steel, this gauge is ready for the shop floor. It won't rust out in your toolbox, and the numbers are etched in black so you can read them clearly, even under a welding hood or in low-light conditions. One of the best features of the MG-8 is its versatility; instead of carrying a pocketful of different gauges for undercut, throat size, and bevel angle, you get everything you need in one device. The sliding pointer and rotating dial are smooth to operate and can be locked in place to hold a measurement for closer reading.

Why every welder needs an MG-8:

• Check Your Fit-Up: Before you even strike an arc, use the gauge to measure the angle of your bevel (0-60 degrees) and check for high-low misalignment between plates or pipes. Good fit-up is the key to a good weld.
• Monitor Undercut: Undercut is a common defect that can cause inspection failures. The MG-8 has a sharp probe specifically designed to measure the depth of undercut so you can fix it before it becomes a problem.
• Verify Weld Size: Don't overweld and waste money on filler metal, and don't underweld and risk structural failure. Use the gauge to check both the leg length and the throat size of your fillet welds.

Whether you are a student learning the trade or a seasoned pipe welder, the MG-8 Cam Type Gauge is an investment in your craftsmanship. It helps you self-inspect your work, giving you the confidence that when the CWI comes around, your welds will pass with flying colors.
