Welding Gauges
Brief Description :

The finished welds shall be visually inspected and shall conform to the size and contour specified in the drawings (Acceptable and defective weld profiles are illustrated in Fig. 24 to 28). Conformity of fillet welds as to size and contour shall be determined by the use of gauges (See Appendix ‘B’) Concavity and excessive convexity of fillet welds shall be marked for correction.

Welding gauges are essential tools in the welding industry for measuring, inspecting, and evaluating welds. Made of metal or plastic and available in various shapes and sizes, they ensure welds meet required standards for strength and durability. These gauges help maintain weld quality by providing feedback on weld profiles, joint fit-up, dimensions, and welding parameters, allowing for the identification and correction of defects.

Fillet Weld Gauges are tools used to measure the size of fillet welds, which are commonly found in lap joints, T-joints, and corner joints. These gauges usually feature a set of blades or notches in various sizes and are used for measuring various weld parameters.

Fig. 2: Method of Gauge Application

1. All dimensions are in millimetres.
2. Gauge for each weld size to be manufactured to the dimensions given in the table above.
3. Weld gauge size to be marked at location’s in 3mm letters, other marking in 2mm letters.
4. All markings to be done on both faces.
5. These gauges are suitable for inspection of normal fillet weld of sizes 5 to 25mm with angle between fusion face of 90 for deep penetration weld and for any other angle between fusion faces, special gauges may be made.
