Welding Inspection

Welding is the most widely used application for the joining of materials used the manufacturing of ferrous and non-ferrous weldments in castings, forgings, valves, machined parts, pressure vessels, and steels structures.

WELDING NDT OVERVIEW

Liquid penetrant is quick, reliable, versatile, and inexpensive. It requires minimal equipment and is sensitive to small cracks.  These qualities make it the most widely used means of weld inspection for the detection of discontinuities that are open to the surface.

WELD INSPECTION

Met-L-Chek penetrant materials are low in fluoride, chloride, and sulfur, and approved for the safe use on metals in accordance with weld inspection standards ASME B&PVC (Boiler and Pressure Vessel Code), ASTM E-1417 and E-1418, NAVSEA, and MIL-STD-2132.

Welding Inspection Products

Our liquid penetrant and magnetic particle materials are certified to meet the requirements of AMS, ASTM, ASME, ISO and OEM specifications.
