Product Description :

Vertical down

The design emphasis of the chemically basic flux has been engineered to ensure

a very fast freezing slag that imparts to the electrode the rather unique ability to

be used for vertical down welding.

The flux coating also contains the appropriate alloying and deoxidation elements

to ensure the weld metal properties demanded by the specification are fully met.

The blend of silicates used ensure both the strength of the flux coating and

resistance to subsequent moisture re-absorption.

Welding Features Of The Electrode :

As the electrode is designed for vertical down welding, particularly fillet welds

with joint access.

The electrode can be used AC or DCEP with the electrode at an angle of 45 to

80 derajad from the vertical with a short arc technique with no weaving. Starts and restarts

should be made with a back step technique.

Fillet welds have a very slight convex profile and the weld metal appearance is

smooth and bright.

Application And Materials To Be Welded :

Medium and high tensile carbon-manganese steels with UTS of up to 510N/mm2

max. Typical grades: BS1449 plate and sheet BS4360 grades 43A and 43C

Lioyds A & D ship steel BS4360 grade 50B, Lloyds grades AH and DH BS3059

and BS3601 grade 320–410 API 5L A-B and X42, BS4360-50B-50C-50D,

BS1501-151 430-490, BS3602-410-460.

Such steels are used in ship construction, bridge building and pressure vessel

work as well as general construction work.
