The selection of flux for roller surface strengthening should be fully considered according to the steel grade, plate thickness, joint form, welding equipment, welding process and required performance, so as to determine the combination of welding wire and flux that can meet the requirements. Next, let's talk about it by Xiao Bian
How should sj101 flux be affected with damp!
Sj101 flux has good welding process performance and slag removal performance when it is greater than 400A. It can flexibly transfer alloy to weld, and meet different performance and composition requirements. It is suitable for the situation with higher requirements for slag removal and mechanical properties. However, sj101 flux is easy to absorb and needs to be baked before welding and used with baking.
Generally speaking, the flux with higher basicity value has less impurities in the weld and sufficient alloy transition (sintered flux), which can meet the requirements of higher mechanical properties, but it has strict requirements on the surface quality of the groove, and should use DC power supply and reverse operation. Sj101 flux with low basicity value has the unavoidable existence of weld impurities and harmful elements, which limits the further improvement of weld performance. However, it has the advantages of low requirements for power supply and appropriate relaxation of requirements for groove surface quality.
The selection of welding flux should be based on the steel grade, plate thickness, joint form, welding equipment, welding process and required performance to determine the combination of welding flux that can meet the requirements.
