THE EFFECT OF THE SURFACING MODE ON THE FORMATION AND DIMENSIONS OF BEADS, WELDED SELF-SHIELDED FLUX CORED WIRE ON FLAT AND CYLINDRICAL PARTS

The dependence of the effect of current and voltage of surfacing on the formation and geometrical parameters of the weld beads for open arc surfacing on flat and cylindrical parts are defined. It is established that in both cases there are almost identical depen-dence on influence of surfacing modes on the width and the proportion of the base metal in the deposited. The influence of the offset from the zenith axis of the electrode for surfacing on cylindrical parts to a penetration depth is established. This allows the use of flat samples at the selection of optimum modes for surfacing cylindrical parts.
