SJ501M is an aluminium–titaninum acid sintered flux,and its alkalinity is approximately 0.5.The flux is shaped as round grains with its grain size of 1.3-0.28mm(14-60 mesh),which is used with either AC or DC.The welding wire is connected to the positive electrode when used with DC.It has stable arc combustion,good slag detachability,and  a good appearance of weld ,it is especially suitable for high speed welding with a strong pore resistance.

As a peculiar production technique is adopted,the flux possesses better moisture resistance and good strenght of grains,which may satisfy the requirements for regular transportation,storage and recycling use in welding ,then flux has less specific gravity when it is bulk packed.And it is consumend less during the welding.

Usage

Consumed matching with H08A welding wires,it may weld key low-carbon steel and some low-alloy structure steel,such as boilers ,pressure vessels,etc.The welding speed may be over 70/h when it is used in welding the membrane water-cooled wall of electric station boilers.

Cautions:

1. The welding flux must be baked for 2 hours at the temperature of 300-500 before being used.
2. Some foreign substance such as rust,grease and moisture on the weldment should be removed before welding.
