Panding Brand Fused Flux LH-HJ151
Smelting flux Strip welding LH. HJ151
Characteristics:
1. LH· HJ151 is a kind of smelting flux of non-Mn and mid-Fluoride. It is like blue-grey or dark-grey pumice particles with the grain size of 10-60 mesh( that is 1.7-0.25mm).
2. During the course of welding, direct current main should be adopted while welding wires or bands are connected to the positive electrode.
3. In application it has the advantages of good welding performance, fine detachability and beautiful bead appearance.
4. HJ151 is characterized by less C addition and less loss of Cr when used in the
Welding of austenitic stainless steel.
Applications:
1. It can be used in the strip surfacing in conjunction with austenitic stainless welding
Wires or bands (such as HOCr21Ni10, HOCr20Ni10Ti, HooCr24Ni12Nb, HOOCr21Ni10Nb, HOOCr21Ni10, etc. ).
2. It is suitable for the build-up welding of nuclear containers and petrochemical equipment's corrosion-proof layers, for the surfacing of pressure vessels and manufacturing of hot-wall hydrogen furnaces, etc.
3. HJ151 is also used in the repair welding of austenitic manganese steel in conjunction with HOOCr16Mn16 welding wire.
Performance of Surfacing Layers:
1. It can be used in the transition-layer welding in conjunction with HOOCr26Ni12 and in the build- up welding of 50mm-thick 18MnMoNb steel plate in conjunction with HOOCr21Ni10 as the surface-layer welding band.
2. Mechanical Performance( See the attached list).
C addition on the surfacing layer is no more than 0.01 percentage, and Cr loss
Is no more than 1.5 percentage.
After the sensitizing treatment, the intergranular-corrosion samples have passed the Test
GB4334.5--- Testing Ways to Stainless Steel Corroded by Sulfuric Acid--- Copper Sulphate bluestone.
CAUTIONS:
Impurities on the welding surface must be removed before welding, such as oil soil, moisture, iron rust, etc.
The welding flux must be baked for 2 hours at the temperature of 300-350 centigrade before build-up welding.
