METHOD OF AND DEVICE FOR ARC WELDING WITH NONCONSUMING ELECTRODE AND FEEDING OF FILLER WIRE Russian patent published in 1997 - IPC

FIELD: motor building, shipbuilding, oil and gas, instrumentation and other industries. SUBSTANCE: in proposed method of arc welding with NONCONSUMING electrode, filler wire is fed continuously and reciprocating motion imparted to wire. Electrode and dialer wire are installed at angles from 15 to 20 and from 40 to 45 degrees relative to vertical, respectively, at different sides, and arc gap is set to 2-3 mm. Filler wire feeder has continuous wire feeding mechanism and mechanism providing reciprocation of wire consisting of electric motor, reduction gear, cam secured on reduction gear shaft, spring-loaded lever and holder. One end of lever has roller engaging with cam, and other end is connected with holder installed in cylindrical housing for longitudinal displacement and coupled with flexible hose. EFFECT: enlarged operating capabilities. 2 cl, 2 dwg, 1 tbl
