Abstract
A method and apparatus for testing the entire length of round material, such as pipes, helically moving in a longitudinal direction. Testing mechanisms are maintained along the path of the pipe and are adapted to move with the pipe to test the pipe in motion. The testing mechanisms are transported fixed distances and returned to starting positions to again move with the pipe such that each testing mechanism tests finite segments of the pipe, the testing mechanisms being so spaced as to assure that the entire pipe is tested. Such testing in motion prevents any untested areas from existing on the pipe.
