Abstract

As the application of on-line monitoring system is shown to be a good
solution during monitoring of main welding parameters at different welding processes, this paper describes application and upgrading of an on-line monitoring system developed at the Mechanical Engineering Faculty in Slavonski Brod. The experiment described in the paper shows application of an on-line monitoring system during welding of two types of studs with application of activating flux for ATIG process (VS-2E) on the base metal surface. Monitoring of the main welding parameters (welding current and voltage) was conducted during welding of studs usually used in steam boiler production (stud diameter: 10 mm), and welding voltage was monitored on the studs (shear stud) of 22 mm diameters used in bridge construction. The goal of monitoring and analysis of main welding parameters is to evaluate the connection of electric arc parameters variations with the presence of an activating flux.
