Considered are current developments in the field of electrode wire feed mechanisms for welding, surfacing and cutting of steels and aluminium alloys. Classification of the main types of feed mechanisms is given. Of particular interest for welding specialists are the mechanisms that feed electrode wire with controlled non-stationary character of movement (intermittent, modulated or pulsed feed). Advantages and drawbacks of some ingenious designs of the pulsed mechanisms are considered.
Keywords: mechanized arc welding equipment, electrode wire, feed mechanism, classification, feed methods, non-stationary process control
