Fe-05 I type anti-friction build-up welding rod
(high-carbon high-chromium anti-friction alloy build-up welding rod)
Accord with Q/HHJ02-2003
Uses: this welding rod can do build-up welding on the low-carbon steel/high-carbon steel/low-alloy steel(for example: A3、Mn13、16Mn、65Mn).it can be also used at some Ferro steel. It has been widely used in the manufacture and restoration for part that are liable to wear such as the brick making machine’s rimer and Strike mud board which belong to the coal chemical industry or the building material and the mechanical trade. The single track build-up welding layer’s hardness: HRC≥60.

Technique: adopt the hand work arc welding. Direct-current transposition. Alternating-current/direct-current.
Build-up welding current: AC: 170-200A. DC: 160-180A. the dilution ratio of the build-up welding layer≤50%.
Fe-05 Ⅱtype welding rod
Accord with Q/HHJ02-2003
Uses: The build-up welding metals possess high hardness and anti-friction and perfect crack resistance. It can be used in the trade of brick making/tile making/cement/glass/ceramic and so on for the build-up welding and remedy of the hammer and all kinds of parts that have been impacted. Build-up welding layer’s hardness: HRC 55~58.
Technique: hand work arc welding. Alternating-current/direct-current.

Fe-05Ⅲtype welding rod
Accord with Q/HHJ02-2003
This welding rod is chrome-molybdenum-vanadium who’s the Chromium mu vanadium type of the low hydrogen sodium type poisons skin .because of its mixture of A and M, it is pliable but strong and of perfect crack resistance when it is as-welded. Adopt the direct-current transposition, mainly be used in the build-up welding of worn part that caused by the violent impact. It can resist impact heat and wear. For parts of the hydro machinery/dredging bucket /rubber plastic machinery and mine machinery have been worn by silt ,the build-up welding layer will leave no crack.
Build-up welding layer’s hardness: HRC 50~55.

Points for attention:
1.the welding rod should be baked for 1h at 330~350℃.
2. The large work should be properly preheated to about 300℃ and then clear the impurities on the surface of the build-up welding parts.
