EXPERIMENTAL AND STRUCTURAL ANALYSIS ON TENSILE AND IMPACT STRENGTH OF THERMIT WELDING

摘要

War-broken parts can be repaired quickly without electricity and gas in the wild by use of the thermit welding technology, so it is of great significance to study on welding quality of thermit welding parts for the its military application. As the tension and impact strength of weld parts are important targets to estimate the welding performance, experimental and structural study have been conducted on test specimens made of Q235 welding parts to develop the influences of technic parameters on the tension and impact strength of thermit welding parts,providing basis for the determination of an optimized group of welding technic parameters.
