Hybrid method of controlling arc welding process with consumable electrode and related processes
IOP Conference Series: Materials Science and Engineering(2019)
Abstract
Abstract For the development of a classical method of mechanized arc welding with a self- regulation of the process of melting the electrode supplied to the welding zone at a constant speed, the following combination was proposed: on the one hand, a digital power source with automatic control and programming of volt-ampere characteristics VAC, which is a two-step one in our case: a – for increased arc length (with a low current), b – for shortened arc (with a high current); on the other hand, self-regulation of the melting process by the corresponding reaction of the power source. Moreover, the electrode melting occurs in a programmed oscillatory mode between the extreme values of the arc length: maximum and minimum. Such a combination is called a hybrid method of controlling the process of arc welding with a consumable electrode.
