Study on Measures against Spot Weld Fracture of Ultra-High-Strength Steel Frame (Sixth Report)

- Study on Measures against Fracture in Heat Affected Zone around a Joining Point by Spot Welding (Part 3)-

Abstract

Fracture by tensile loading could be made cause in heat affected zone around the spot weld point. On prebious report, a flange shape that achieved both the performance of the member and suppression of the fracture was found by 4 point bending test simulation. On this report, the flange shape which reduces the tensile stress was considered by 4 point bending test. Therefore, as aresult of experimentally verifying the effect of the flange shape by 4 point bending test, it was confirmed that the member was as expected in the previous report.
