Screen weld joint test method and apparatus

摘要

A test specimen, including a single rod segment and arcuate segments of the wrap member welded to it is removed from the screen and supported between base and cover portions of a specially designed test fixture, which is operatively positioned in a conventional spring test machine that exerts compressive force on the fixture. A compressive force is exerted on the fixture to forcibly move the base and cover portions toward one another. The base and cover portions of the test fixture are configured such that the compressive force is converted to a tensile force exerted on a selected single rod/wrap weld joints in the specimen, with the spring test machine recording the tensile force exerted on the weld joint at its breakage.
