Bulge test equipment for portability type simple welding

摘要

(57) Abstract Objective Simplicity expediting and welding of bulge test of steel sheet weldImprovement of evaluation precision of part quality. Constitution In device itself of portable type test piece mount base, manually operated testIt possesses the one fixture and the hydraulic ram cylinder. DeviceAt the small-sized hydraulic pump which is installed in the computer the hydraulic ram cylinderThe circuit configuration which is operated it forms. In device itself, ramushiriBrattice quantitative measurement gauge and the remaining needle die which measure the movement magnitude of nda2 stylus pressure power gauges are had. As for bulge test, test pieceAt the test piece fixture to lock on test piece mount bench top, small-sized oil pressureTo activate the pump, at the hydraulic ram cylinder the weld breakingIt does due to se ru thing.
