DEVICE TO TEST WELDS IN STRIPS OR WIRES

摘要

FIELD: equipment testing quality of welds for multicyclic fatigue. SUBSTANCE: device to test welds in strips or wires has frame carrying system of rotary bending rollers arranged in staggered order and coupled to drive of their rotation. System of rotary bending rollers arranged in staggered order is equipped with mechanism adjusting their positions and transmitter of sagging of specimen of strip or wire welded into closed endless structure, supporting rollers to position given closed endless structure are mounted on both sides of system of rotary bending rollers arranged in staggered order. Revolution counter is put on shaft of one supporting roller, another roller is coupled to tension mechanism carrying transmitter of tension force. EFFECT: raised productivity and authenticity of process testing specimens of welds of strips or wires. 1 dwg
