Bridge Cam Weld Gauge — GAL
The GAL CAT 4 Bridge Cam weld gauge combines several weld-profile measurements in one inspection tool. Check bevel preparation, weld reinforcement, fillet dimensions, undercut, pits and outside misalignment using inch and metric scales.
Multi-function weld profile inspection
The GAL Bridge Cam Gauge, CAT 4, helps inspectors check joint preparation and accessible weld surfaces during fabrication and maintenance. It measures geometry; weld acceptance still depends on the applicable drawing, welding procedure and inspection criteria.
Measurements available
- Bevel preparation angle, from 0° to 60°.
- Excess weld metal or reinforcement height.
- Fillet-weld throat dimension and leg length.
- Undercut and surface-pit depth.
- Outside misalignment between adjoining surfaces.
Using the correct reference surface
Seat the gauge on clean base material and position the measuring tip or slide against the feature being checked. Keep the gauge square to the measurement and read the appropriate scale. Use the manufacturer’s instructions for the selected function, particularly when distinguishing actual throat measurement from theoretical fillet size.
Record the measured value against the job’s acceptance limit. A scale graduation or example reading is not, by itself, an allowable weld defect or an instrument calibration certificate.
Select a weld inspection gauge
Specify CAT 4 when requesting this Bridge Cam model. Tell Justram which dimensions you need to inspect and whether your quality system requires calibration documentation.
For dedicated pit and undercut measurement, see the GAL CAT 5A Pit Depth Gauge. For surface weld-profile checks, compare the V-WAC weld gauge, or browse our pipe fit-up and alignment tools.
