Product description and

main applications

FK422 is a carbon steel electrode with a titanium-calcium coating. It can be used for both AC and DC, and
can be used for all-position welding. It has excellent welding process performance and good mechanical properties;
stable arc, small spatter, easy to remove slag, and easy to start arc again; beautiful welding seam shape, welding
wave can be wide, narrow, thin, thick, loose welding, efficient High; used for welding important low-carbon steel
structures and low-alloy steel structures with low strength grades, such as Q235.09MnV, 09Mn2, etc.

Product description and

main applications

FK502 is a carbon steel electrode with titanium calcium coating. Both AC and DC can be used for all-position
welding. It has excellent welding process performance and mechanical properties, stable arc, little spatter, and
easy slag removal; beautiful welding seam shape; mainly used for welding low-gold steel structures with tensile
strength of 490MPa, such as rebar for construction and other 16Mn Welding of structural steel.

1. The electrode must be baked at
300~350~C for 1h before welding.
2. For surfacing welded high-manganese

steel workpieces, the fatigue layer should be removed in advance or treated with water toughening or chromium-manganese steel welding rods (such as D277) should be used for bottoming.
3. There is a lot of yellow smoke during surfacing. Pay attention to strengthen the ventilation shaft to operate at the upwind position

Product description and main applications

FK266 is a low-hydrogen potassium type coating high-manganese steel surfacing electrode, which can be used for
both AC and DC (when AC welding, the no-load voltage is not less than 70V), and small current should be used
for surfacing. Narrow bead, hammer or water quench immediately when it is red hot: to reduce the tendency of cracks.
The surfacing metal is austenitic high manganese steel, which has the characteristics of work hardening, toughness and
wear resistance. Because Mo is added to the weld metal. Thereby improving the crack resistance and wear resistance;
suitable for surfacing welding of various crushers, high manganese steel rails, buckets, pushers and other parts that are
subject to impact and easy to wear.

2. Try to use small current and short arc welding when welding
3. The weldments must be cleaned of rust, oil stains, moisture and other impurities before welding.
