Approvals
Avesta’s 3D range has been specially developed for flexible welding in all common welding positions except vertical down. Extremely good
weldability; the arc is stable and weld pool and slag are extremely easy to control. Should be welded using a short arc with its coating sliding
along the work piece and both AC/DC can be used but DC (+) preferred. The Avesta 308/MVR-3D is a Cr-Ni electrode for welding of 304 and
304L stainless steel.

Avesta 347/MVNb AC/DC is a Nb stabilized Cr-Ni electrode for welding Ti stabilized steels such as ASTM 321 and 347 exposed to service
temperatures exceeding 400˚C.Should be welded using a short arc with its coating sliding along the work piece and both AC/DC can be used
but DC preferred. Constructions with lower service temperature can be welded with Avesta 308L/MVR-3D, which offers better resistance to hot
cracking.

AVESTA 4D is a thin-coated, rutile-acid type electrode specially developed for the welding of thin walled pipelines and sheets, mainly in the
chemical process and papermaking industries. It is characterised by its exceptionally good arc stability, weld pool control, slag removal and
restriking properties. Should be welded using a short arc with its coating sliding along the workpiece and both AC/DC can be used but DC
preferred. This makes it highly suitable for welding in restrained positions and under difficult site conditions, where it offers considerably
higher productivity than manual TIG welding. It is also recommended for root runs and multipass welds in general fabrication of ASTM 316
type stainless steels in all material thicknesses. Avesta’s 4D range has been specially developed for flexible welding of thin stainless sheets and
pipes. Avesta 4D electrodes is often a quick and cost-efficient alternative to TIG.

Avesta 309L-3D is an over alloyed low carbon electrode designed for dissimilar welding between stainless and mild or low-alloyed steels.
Should be welded using a short arc with its coating sliding along the work piece and both AC/DC can be used but DC preferred. The electrode
is also well suited as a buffer layer when performing overlay welding on mild steels, providing an 18 Cr 8 Ni deposit from the very first layer.
Over alloyed electrode for surfacing unalloyed steel, joint welding non-molybdenum-alloyed stainless steel to unalloyed steel and welding clad
material.

weldability; the arc is stable and weld pool and slag are extremely easy to control. Should be welded using a short arc with its coating
sliding along the work piece and both AC/DC can be used but DC preferred. Avesta P5-3D is an molybdenum-alloyed low carbon electrode
corresponding to AWS A5.4 E309MoL-17. This highly alloyed 23/13/3L electrode is suitable reliable, crack resistant welds between stainless steel
of the ASTM316/316L type and mild or low-alloy steels and can also be used for overlay welding , providing an 18Cr 8 Ni 2 Mo deposit from the
very first layer.
Specially designed for difficult-toweld
such as Mn-steel, tool steel,
high temperature steel grades. Also
for welding stainless to unalloyed
steel.

Avesta P7 is a highly alloyed Cr-Ni electrode with approx 40% ferrite offering high tensile strength and excellent resistance to cracking. The
chemical composition corresponds to that of AWS A5.4 E312. The electrode is primarily intended for dissimilar welding between stainless steel,
tool steel, spring steel, and 14% Mn steel as well as other difficult to weld combinations.
