Welding current and total voltage measurement by a current probe (Tektronix TCP404XL) and a differential probe (Tektronix TDP0500) and recorded by an oscilloscope (Tektronix DPO4104).

\n

Arc and wire image recording with a monochrome high-speed camera MotionPro Y4, frame rate of 6000 fps, exposure time of 16 \u00b5m, parallel to the workpiece and in welding direction, synchronous recording through two different narrow-band spectral filters with the central wavelengths of 437nm and 811nm to image the radiation of the metal vapour and those of the argon shielding gas.

\n", "procedure": "

The total voltage was measured between the contact tube of the welding torch, where a specific junction has been mounted, and the workpiece.

\n

An image processing via Matlab has been used to treat arc images recorded with the two different filters, to reconstruct the metal vapour range and the shielding gas range of the arc and to estimate the arc column length.
