AV EZEWeld Flux 17L is an aluminate basic agglomerated flux for submerged arc welding bearing

very high current carrying characteristics for DC+ . It has very good operational properties for both single and multi wire systems. It gives excellent impact values at very law temperature and very low oxygen in welding.

Typical Application

AV EZEWeld Flux 17L can be used for fillet welding and single / pass butt welding of mild , medium

and high tensile steel. The required strength of the weld metal is achieved by proper selection of alloyed wires. It is used for narrow gap welding due to superior slag detachability and smooth blending of weld bead with joint side walls.

Note on Usage
Dry the Flux at 300-350°C (572-662°F) for 60 minutes before use. Pay attention to welding voltage. Excessive welding voltage causes deterioration of joint Properties.
Add new Flux periodically to prevent the weld defects and bad appearance which occurs when continuously reusing the flux.

AV EZEWeld GR 26 is a all mineral non-alloying flux and the weld metal can be fully controlled independently of the welding parameters through suitable choice of wires.

This makes AV EZEWeld GR 26 suitable for multi run welding of thick materials using single wire as well as multiple wire technique. AV EZEWeld GR 26 is designed for multipass welding of mild, medium and high tensile steels as well as low alloyed steel with impact strength requirements between -40°C and -60°C. It allows for high current carrying capacity on DC+ is specially suited for narrow gap welding due to its excellent slag detachability and and smooth blending with the side walls.

Typical Application

Pressure vessels for nuclear applications and offshore constructions where good COD values required are the areas where AV EZEWeld GR 26 is successfully used. AV EZEWeld GR 26 gives the weldmetal a low oxygen content (approx. 300 ppm) and low hydrogen content deposit (lower than 5 ml/100 g).
