Description

Description:
      HJ**1 is a kind of smelting-type,red brown to light yellow colored,glassy granulated flux with high manganese and silicon but low fluorine,mesh ***4(2.**1.5mm),***0(2.**0.*5mm) and ****0(1.**0.*5mm). 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:
When applied to welding wires such as H*8A,H*8MnA and H*0MnSi,it can weld low-carbon steel and some low-alloy steel like *6Mn and *5MnV,as well as ships,boilers and high-pressure vessels. And it also can be used for electro-slag and copper welding.
Cautions:
1.The oil soil,moisture,iron rust and other foreign substances must be removed from the surface before welding.
2.The flux must be baked under ******0℃ for 2 hours.
