FL 188 SAW Arc Submerged




FL 188

 
CATEGORY 
TYPE 
Agglomerated semi-basic flux suitable for carbon alloy steel welding in single and multipass technique and in single or multi-wire applications.
APPLICATIONS 
Boiler works, pipes, ship building, structural steel works, tanks and pressure vessels, offshore applications etc..
PROPERTIES 

The weld deposit produced in combination with corresponding sub-arc wires meets outstanding mechanical properties and in particular high toughness at low temperature. The flux is suitable for single and multilayer welding of longitudinal and circumferential and fillet welds. It can be used for single, tandem, twin and multi wire welding systems. Excellent slag removal in narrow groove welds of thick wall sections.

 

  • Basicity ~1,7 (according to boniszewski)
  • Current: DC or AC, in single or multi-wires up to 1000 Ampere per wire
  • Grain size acc. EN ISO 14174: 2 - 16
