Multiple MAG Repair Welding of Steel S1100QL with the Removal of Defective Fragments of Welds Using Mechanical Treatment
Journal Title: Biuletyn Instytutu Spawalnictwa - Year 2018, Vol 62, Issue 5
Abstract
The research discussed in the article involved the performance of tests assessing the effect of a one-time and four-time repair welding thermal cycle on mechanical properties of 18 mm thick butt joints made of toughened steel S1100QL. The tests also involved the determination of mechanical properties of a production joint and joints subjected to mechanical treatment-based repair, involving the use of the MAG method (138) and metallic flux-cored wire STEIN-MEGAFIL 1100 M. It was ascertained that the mechanical properties of the joints subjected to mechanical treatment-based repair were similar to those of the joints subjected to repair welding involving the removal of a defective part using arc-air gouging.
