DIAGNOSTIC EQUIPMENT > welding gauges

Measurement and inspection of welded joint is an important step in quality control and reliability of welded constructions. External inspection allows you to detect such external defects such as undercuts, uncertified craters facing surface cracks, lack of fusion, flows, etc. Meters of welded joints and welding templates (templates welder) allow us to determinethe size of joints, joint width and high, angle of bevel, depth and widht of preparation, included angle, root gap, dept of root face, convexity, smoothness of transition weld to the base metal, leg length, etc.

We delivery welding inspection feet, Level of regulation (wrong side of the feet), universal and specialized welding gauges, etc.

All scales - metric.

Welding gauges made of stainless steel.

Each template has exactly made undercut certain leg. For convenience, control next to each recess knocked size corresponds to the radius of the leg joint. Control leg weld produced by successive contact (selection) petals connected with welding details. Size is considered established if the long side lobe and bridge between adjacent legs of the petal to detail with no visible gap, and the gap between the arcs and petal seam is minimal.
Welding inspection feet WG 6 The product mainly consists of a main ruler, a slide gauge and an oblique gauge.
