FEATURES :

BUILD UP ON CARBON STEELS IS FACILITATED DUE TO HIGH STRENGTH WELDMENTS. IT ENABLES BUFFER/CUSHIONING FOR HARDFACING OVERLAYS IT ALSO RESTORES ORIGINAL DIMENSIONS BY MULTILAYERING IT HAS GOOD COMPRESSIVE STRENGTH THEREBY ABSORBING HEAVY IMPACT IT IS MACHINABLE MANGANESE STEELS OR CAST IRONS ARE AVOIDED JOINING IS NOT RECOMMENDED.

IT IS SUITABLE FOR RESISTING FRICTIONAL WEAR AS ALSO ROLLING SCOUR.

PROCEDURE :

GOUGING/CUTTING/GRINDING IS DONE TO REMOVE FATIGUED /WORN OUT SURFACE. STRINGER BEADS ENABLE SUPERIOR SURFACE MODIFICATION

TECHNICAL DATA :

FEATURES :

It is a basic coated electrode combating wear due to friction and compression. Alloy chemistry enables welds with multilayer welding. It is so formulated to produce extra low hydrogen without any underbead cracking. Low spatter and thick deposits are of radiographic quality welds.

APPLICATIONS :

Reclamation of worn-out points, rollers, equalizer beams, guide rolls and others.

Chemistry :

FEATURES :

Basic low hydrogen type weldments are martensitic type, with fine, evenly dispersed Cr-Mo-V carbides. Thick, dense beads are radiographic and crack-free enabling 3-layer deposits. All position welding with good slag detachability on low-, medium-, and high- carbon steels makes it welder-friendly. It is eminently suitable for wet (soil) and dry abrasion.

APPLICATIONS :

Plough shares, cutter blades, sprockets, augers, crusher rollers, mill rollers, screen conveyors, tillage machinery parts, agro parts and others

Procedure

Wear-prone or fatigued surface is gouged or ground. Stringent beading in criss-cross or dot/dash pattern enhances wear resistance

Chemistry :

FEATURES :

Specially formulated coating gives dense, pore-free, radiographic quality welds in all positions. Smooth, low spatter, negligible smoke and bright shiny .Slag detaches easily.

APPLICATIONS :

Extra low carbon content ensures no risk of weld decay ie carbide precipitation is reduced. It is applied where operating temperature is upto 350 C AISI 301, 302, 304, 304L, 308 and 308L. Dairy, foodstuff, chemical industries and fertilizer plants parts and components of similar.

Mech Properties

WELDING DATA AC/DC(+)

FEATURES :

It is used for combating thermal wear, avoiding deformation of parts. It is stable at elevated temperatures, resisting hot cracking, due to NIL ferrite.

APPLICATIONS :

The Alloy-rich welding finds applications in welding furnace components, heat treatment parts, burners and nozzles

PROCEDURE :

Grease oil and others are removed . Avoid weaving. Using lowest possible amps, maintain short arcs.

Mech Properties

WELDING DATA AC/DC(+)

FEATURES :

Dense thick welds are of radiographic quality. Flux is so formulated to please the welder so also the metallurgist alike. Soft fusion and less spatter in all positions characterize the weld. Slag removal is easy with good arc striking and restriking.

It is a lime-titania type electrode with a good weldability. As the all-weld metal has an austenite structure having adequate ferrite, crack resistance is excellent. It resists intergranular corrosion due to carbide precipitation in the as-welded condition since carbon content is less Service temperature ranges from -120 C to + 350 C.

APPLICATIONS :

It finds extensive applications in nuclear reactor, chem., petrochem, pharma food and beverages and dairy, paper and fertilizer industries.

PROCEDURE :

Grease, Oil and others are cleaned. Weaving is avoided. Medium current and short arc result in strong and ductile welds.

TECHNICAL DATA AC/DC(+)

Application field

It is suitable for cutting, chamfering and piercing all industrial metals.

Cutting properties

It strikes easily and achieves clean cuts even on thicker materials, in view of its high current – carrying capacity.

Cutting instructions

Set up the workpiece so that the molten metal can run off easily. It is advisable to execute an up-and-down sawing  movement, pushing the molten metal away with the electrode. Depending on the electrode diameter and material thickness, the amperage is varied between the limits indicated below.
