Welding Electrode Production Line
Brief introduction of production technology of welding electrode
The manufacturing process of welding electrodes must go through
multiple processes, which can be summarized into eight main
processes:
1. Processing of welding core
a. The carbon steel disk circle enters the shell peeling and
derusting process through the shell peeling machine to clean the
oxide scale and rust spots on the surface of the wire rod.
b. The wire rod is rolled into taper shape by using a tip rolling
machine, and the tapered wire rod after the tip rolling is passed
through the wire drawing grinding tool.
c. Use a wire drawing machine to thin the wire rod to the diameter
required to produce the welding core.
d. Use the wire cutter to straighten and cut the wire rod to become
the welding core.
2. Powder blending
According to the requirements of different brands and
specifications of welding rods, the welding powder of various raw
materials shall be mixed in proportion.
3.Water glass
According to the requirements of different brands and
specifications of electrodes, water glass with different specific
gravity is prepared.
4. Stirring
a. Dry mix the welding powder with a mixer, and mix the welding
powder evenly.
b. Water glass is added to the dry welding powder which is evenly
stirred, and the welding powder is wet stirred.
5. Coating and pressing process
a. It can be divided into two ways of spiral coating and hydraulic pressure coating;
(1) Spiral coating:
The wire feeder forces the processed core from the 45 ° direction
to the spiral coating machine, the spiral machine reamer pushes the
mixed welding powder forward, and applies the welding powder on the
surface of the core through the head.
(2) Hydraulic pressure coating:
Put the welding powder into the hydraulic powder applicator. The
wire feeder forces the processed welding core from 45 ° to the
hydraulic powder applicator. The hydraulic powder applicator pushes
the powder forward and applies the welding powder on the surface of
the welding core through the head.
b. After the powder coating, the welding core falls on the grinding
head and tail machine, and the arc striking end and clamping end of
the electrode are ground out, and then it becomes the electrode.
c. The welding electrode is transported to the front and auxiliary
line equipment through the grinding head and tail machine, the
eccentricity and defective products of the welding electrode are
inspected, and the unqualified welding electrode is recycled and
then produced.
6. Printing process
The trademark and model shall be printed on the electrode.
7. Drying process
The electrode will be dried, after the low temperature preheating
area, medium temperature drying, high temperature drying and
cooling, it will become the electrode.
8. Conduct secondary appearance inspection, weighing, packaging and
warehousing for the dried electrode.
