Description

Description:
      SJ**1 is a kind of silicon-calcium-type sintered flux,mesh ****0(2.**0.*5mm) and basicity *- 1.**1.1. Either alternating or direct current can be used,but welding wires must be connected with the positive electrode when direct current is used.The welding technology has good performance,fine detachability and fine appearance of weld.
Usage:
The flux is fit for the submerge-arc welding of low-carbon steel and low-alloy steel,as well as the fast single-way and double-surface welding of thin steel sheet.And it is usually used for the submerge-arc welding of liquefied gas storage tanks,gas bottles and pipeline steel.
Cautione:
1.The oil soil,moisture,iron rust and other foreign substances must be removed from the welding joint.
2.The welding flux must be baked under ******0℃ for 2 hours.
3.It\'s better to use direct current.
