Design And Manufacture Of Manual Electrode Coating Machine For Small - Scale Arc Welding Electrode Manufacture

ABSTRACT

Local production of elechodes. in Nigeria has always bpb~y m ajor

manufachmrs. The technical partrsers have maintained that there are no

suitable substiW!es for the raw materials locally in an attempt to continue b

import from *eit. 'h~.~coqn@esOu r effort at .lpwl sourcing required

experimentation. Mi could not be carried out without a Wns of applying

the coatmg to. the wire. This was effected through a direct exhder. which

was fabricated to mat eWodes.pnder manual presswe .bu@ up through a

plunger in an extrusion chamber. Om a wire was mated. the plutqer was

withdrawn to remove the pressure. The ektde-coating Mine 1s

expected to find applicahm in research laboratories of tertiary institutions and

wall scab manufacturing outhts.
