Weld Gauges (Bridge Cam)

Weld gauges are an everyday tool for Certified Weld Inspectors. Gauges are available for checking alignment, checking dimensions before welding, verifying weld dimensions, and for measuring the size of porosity, among other items. Gauges can be single- or multipurpose. 

 A bridge cam gauge can provide a variety of measurements.

This type of gauge is a unique, versatile instrument for the inspection of welded surfaces and joints. It can measure the following:

Angle of preparation from 0 to 60 deg

Excess weld metal (capping size)

Depth of undercut

Depth of pitting

Fillet weld throat size

Fillet leg length

Misalignment (high and low)

It displays measurements in both inches and millimeters (linear measurements up to 60 mm or 2 in.). The gauge is easy to use. It is comprised of one rotating dial and one sliding pointer. You simply move the dial or pointer until it makes the appropriate contact and then read the result.
