WELD Crawler is an extremely versatile and modular scanning solution, combining hardware and software to meet a wide range of inspection challenges. The base scanner is a circumferential scanner that can be used to scan pipes from NPS 2.5″ to flat. The addition of an optional axial package allows the user to effortlessly convert the basic circumferential weld scanner into an axial weld scanner for pipes without the use of tools, while an optional probe frame with additional probes makes inspection of greater wall thicknesses possible.
