Abstract
The issues related to producing of spot joints of structures on vertical plane using mechanized equipment for arc shielded-gas welding were considered. It was established that application of pulse electrode wire feed with controllable parameters allows essential simplification of process of producing welded joint, providing its necessary quality and repeatability of results. The prospects of application of this welding method were shown including also those with application of welding current sources with pulse algorithms of operation synchronized with pulse electrode wire feed.
