Influence of Electromagnetic Fields on Environment in TIG welding process

This paper presents welding current influence on spreading of electromagnetic field in TIG welding process. The quality of welding is analyzed by „Fast Fourier Transformation“ (FFT) on recorded current. Electric and magnetic field are measured using an instrument „Macshek ESM – 100 3D Fieldmeter“ [1]. Welding current is recorded using the On-line monitoring system [2]. Recording parameters of these two devices have synchronization time on On-line interface over hardware pin and interrupt routine in LabView software platform. Scale, resolution and synchronization of measured signals are additionally analyzed in Matlab.
