Welding Cast Iron
 


The Polyweld® 700 Series
 


Polyweld® (AC/DC) - A 99% pure nickel-core wire, developed to operate on any current. Provides outstanding, easily machinable weld deposits for the buildup or joining of cast iron and cast iron to steel.

Specification: AWS-ENiCI
Available forms: E , TIG , MIG

 


Polyweld® 702 (AC/DC) - An excellent AC/DC straight-polarity product for welding cast iron with minimum heat output. The high conductivity of its commercially pure nickel core assures low temperature fusion with minimum dilution of the cast iron base metal.

Specification: AWS-ENiCI
Available forms: E

 


Polyweld® 704 (AC/DC) - A 99% commercially pure nickel-core wire with and electrically non-conductive coating. Developed for welding most cast iron and joining cast iron to steel when arcing out in restricted areas such as deep holes or narrow openings is a problem.

Specification: AWS-ENiCI
Available forms: E

 


Polyweld® 705 (DC-RP) - For a wear-resistant, machinable buildup and overlay on grey, nodular, meehanite and special alloy cast irons. All cast irons mentioned can be surfaced without buffer layers. Used primarily for welding flame-hardenable, automotive cast iron stamping and forming dies (Non-Heat-treatable).

Rc 37 - 40
Specification: NA
Available forms: E , FC

 


Polyweld® 706 - The ultimate for machinable welds pm gray-malleable or nodular cast iron. Provides excellent welds on dirty castiron with readily machinable deposits. Used for the fabrication of cast iron and joining cast iron to steel.

Specification: AWS-ENiCI
Available forms: E

 


Polymatic® 730-FC - A unique 30% nickel flux-cored wire for welding ductile, malleable and grey cast irons or for joining them to carbon steels. Pre-heat is usually required and the weld deposits are machinable.

Work-hardens to Rc 40
Specification: NA
Available forms: FC

 


Polyweld® 747-L - A companion nickel/iron/chrome alloy to Polyweld® 705, with fluxing agents and precisely extruded coating for non-porous, homogeneous, iron-base deposits that are marginally machinable as-welded. Non-heat-treatable.

Rc 46-48 as-welded, work-hardens to Rc 50-55
Specification: NA
Available forms: E

 


Polyweld® 750 (AC/DC) - A 55% nickel alloy with fluxing agents and precisely extruded coating for non-porous, homogeneous, nickel-iron deposits. For welding of ductile, malleable and grey cast irons. Used to overlay cast iron before surfacing with a more wear-resistant alloy and for joining cast iron to steel.

Specification: AWS-ENiFeCI
Available forms: E , FC , TIG

 


Polyweld® 755 (DC-RP) - A 55-45 copper/nickel alloy for excellent color match on cast iron with the ultimate in machinability. May be used as a first layer on high-sulphur steels.

Specification: NA
Available forms: E , TIG , MIG

 


Polyweld® 762 (DC-RP) - An economical, all-position composite electrode for welding most cast irons and joining cast iron to steel.

Specification: NA
Available forms: E

 


Polyweld® 765 (AC/DC) - A very special 65/35 nickel/iron alloy with the same unique coating as Polyweld® 702 for a soft, stable arc, minimum dilution and exceptional weld-bead appearance. Used for welding cast iron and joining cast iron to steel with excellent machinability.

Specification: AWS-ENiFeCI
Available forms: E

 


Polyweld® 777 (AC/DC) - An iron-based electrode that runs well on all currents and either polarity. Used on cast iron when weld deposits do not have to be machined.

Specification: NA
Available forms: E
