Investigation of the welding and technological properties of coated electrodes in welding with modulated current

Abstract

The method of determination of the modulation parameters – the duration of additional pulses in the period of the main break and repetition frequency – is described.

Keywords:

• electrodes
• welding
• modulated current
• pulse
• repetition rate

Notes

^a. The term ‘stability of arcing’ is used in these standard documents. Experiments show3 that the ‘stability of arcing’ does not exist in processes with short circuiting of the arc gap, i.e. arc discharge can be interrupted at the moment of a short circuit between the droplet and the weld pool.
