What is a weld gauge?

A weld gauge is a portable measuring tool specifically designed for weld quality inspection, integrating mechanical construction, laser sensing, or digital display technology. It enables fast and accurate measurement of critical geometric parameters such as weld reinforcement height, thickness, misalignment, bevel angle, and undercut depth. By using either direct contact or non-contact scanning, this weld measuring gauge transforms abstract welding quality into quantifiable data, helping inspectors efficiently determine whether a weld meets international standards or design specifications. Widely used in shipbuilding, pressure vessel fabrication, steel structure construction, and pipeline installation, the welding gauge has become an essential inspection tool to ensure the safety, reliability, and compliance of welded structures.
