Tests of welds are carried out inter-operatively, during the execution of the steel structure, as well as after the structure is welded, but even before its assembly. Steel structures already in service are also examined to detect potential cracks, delamination, or corrosion loss of thickness having the effect of weakening the mechanical strength of the structure. Such examinations are some the elements that comprise a structural health assessment. In this paper, the metal memory method was used to evaluate the effect of the welding method and weld temperature on the change in magnetic field strength. S235JR structural steel was used for the study, which was subjected to milling and MMA, TIG, and MIG welding. The results of measurement experiments carried out for each welding method are presented as graphs.
焊接检测在钢结构施工过程中、焊接完成后以及组装前进行。已投入使用的钢结构也会进行检查，以检测可能出现的裂缝、分层或厚度腐蚀损失，这些情况会削弱结构的机械强度。此类检查是结构健康评估的一些组成要素。本文采用金属记忆法评估焊接方法和焊接温度对磁场强度变化的影响。研究使用了S235JR结构钢，对其进行了铣削以及手工电弧焊、钨极惰性气体保护焊和熔化极气体保护焊。针对每种焊接方法进行的测量实验结果以图表形式呈现。
