| The paper presents the MAGNETARC welding of thin walled tubes achieved with an original longitudinal magnetization system, designed to assure the magnetic flux concentration on tube wall. The research objective was to develop process parametric windows for a qualitative joint achievement. Based on images resulted from process monitoring, the process main stages are presented, from the arc initiation until molten metal appears, upsetting is achieved and the weld forms. Infrared thermography was also used for temperature measurements and visualization of the process. Macro and microstructural analysis accompanies the hardness tests made on correspondingly welded samples, demonstrating the process capability in producing sound joints when guided by the operational windows developed by this investigation. | |
