Abstract

The device for feeding the surfacing electrode or filler wire to the combustion zone of the electric arc is intended for restoring the parts of the machines by surfacing, for example, by high-speed argon-arc surfacing, and for conferring special physical and mechanical properties to the surface of the part during its manufacturing. There are aligning bushings in the body of the wire feeder. The thickness of the bushings is from two to three diameters of the surfacing wire. The device, on the one hand, increases the productivity of the process up to 10 times according to the surface area deposited per unit of time with minimal allowances for subsequent machining, and on the other hand, increases other parameters of high-speed argon-arc surfacing. At the same time, the service life of the surfacing unit is becoming longer due to rectilinear rotation of the filler wire around its axis at the output of the wire feeder mechanism. It is the usage of this device that makes the process of high-speed argon-arc surfacing possible. The device provides six–tenfold increase in productivity on the surface area deposited per the unit of time, reducing energy costs per unit of the weld area by 2 or 3 times and reducing the thermal input to the workpiece by 2 or 3 times in comparison to the conventional argon-arc surfacing.
