WELDING ELECTRODE PRODUCTION PROCESS
There are generally 8 steps for making electrodes
1 Wire coil processing
2 Flux mixing
Mixing raw materials by proportion which should base on different standard and size of welding electrodes.
3 Sodium potassium Silicate
Making proportion of Sodium potassium Silicate base on different standard and size of welding electrodes.
4 Flux mixing
5 Coating procedure
Screw coating:
Feeding wire from wire feed machine to screw extruder by pressure force at the
45 °angle. Then push flux forward by screw in screw extruder to coat the surface of coil.
Hydraulic coating:
Put powder agglomeration into hydraulic extruder while wire feed machine delivery wire to hydraulic extruder by pressure force. Hydraulic extruder push flux lump forward to coat on wire through machine head.
6 Words Printing
Print models and brand on electrodes.
7 Drying
Drying electrodes through low temperature zone, medium temperature zone, high temperature zone, cooling.
8 Second time inspection, weight, packing and warehouse.
