Activating and purifying fluxes for arc welding using the non-consumable electrode in inert gases

Activating (FS-71, FS-300) and purifying (FA-1T, FA-2T, FAM-1T) fluxes are the fine powders intended to improve quality and reliability of welded designs from steels, heat-resistant, aluminum and magnesium alloys.

Activating fluxes allow:

  • to increase fusion penetration depth by 1.5 times;
  • to reduce the weld width by 2-2.5 times at unvaried rate of energy input;
  • to perform weld thickness up to 6 mm in one pass and to improve quality of welded connection.

Purifying fluxes allow:

  • to prevent formation of oxide inclusions and pores in weld metal;
  • to improve weld penetration and give a possibility to perform "suspended" welding;
  • to increase tightness and operational reliability of products.

Activating fluxes

Flux FS-71

Consumption, per 1000 m welds, kg 2,0

Flux FS-300

Consumption, per 1000 m welds, kg 2,0

Brand materials to be welded

  • nickel: HN67MVTU (EP 202), HN57MTVU (EP 590), HN60VT (EI 868), HN55MBU (EP 666),
  • steels: 12H18N10T, 12H21N5T (EI 811), 12H16N25M6AG (EI 395),
  • combination: 12H18N10T+12H21N5T (EI 811), HN55MBU (EP 666) +07H16N6 (EP 288), HN55MBU (EP 666) +12H18N10T.

Purifying fluxes

Flux FA-1T and FA-2T

Consumption, per 1000 m welds, kg 1,0

Marks of welded materials:

Al- alloys:

  • AIMg6,
  • AIMg,
  • 1201 etc

Flux FAM-1T

Consumption, per 1000 m welds, kg 1,0

Marks of welded materials:

Mg- alloys:

  • MA-21

Note:

Flux FA-1T – is used mainly for butt joints.

Flux FA-2Т - for overlapping, interlock and end joints.

Purifying fluxes are not recommended for welding the Li-containing alloys.
