Description
HJ431 is a kind of smelting-type,red brown to light yellow colored,glassy granulated flux with high manganese and silicon but low fluorine,mesh 8-14(2.5-1.5mm),8-40(2.5-0.45mm) and 14-40(1.5-0.45mm). Either alternating or direct current can be used and Welding wires must be connected with the positive electrode when direct current is used. The welding technology has good performance.
Usage&Cautions
● It can be applied to welding wires such as H08A,H08MnA and H10MnSi,it can weld low-carbon steel and some low-alloy steel like 16Mn and 15MnV,as well as ships,boilers and high-pressure vessels. And it also can be used for electro-slag and copper welding.
● The oil soil,moisture,iron rust and other foreign substances must be removed from the surface before welding.
● The flux must be baked under 300-400℃ for 2 hours.
