Heat- and Corrosion-resistant Nickel
and Nickel/Chrome Base Alloys
¡¡
The Weld Mold¢ç 4000 Series
¡¡
Weld Mold¢ç 4141 (DC-RP) - For welding Nickel
200 and Nickel 201 to themselves or each other; welding
the clad side of nickel-clad steel; and overlaying on
steel. The reaction of titanium with carbon in the weld
metal maintains a low level of free carbon and enables
the electrode to be used with the low-carbon composition
of Nickel 201. Dissimilar-welding applications include
joints between Nickel 200 or 201 and various iron-base
and nickel-base alloys.
Specification: AWS-ENi-1
Available forms: E , TIG , MIG
¡¡
Weld Mold¢ç 4182 (DC-RP) - Used for welding
Inconel¢ç alloys 600 and 601 to themselves or each other.
This alloy can produce weld deposits that meet stringent
radiographic requirements. Dissimilar-welding
applications include joining Inconel¢ç alloy 800 to
carbon steel, stainless steel, Nickel 200 and Monel¢ç
alloy 400 to carbon steel; joining Monel¢ç alloy 400 to
carbon steel; joining Nickel 200 to stainless steel; and
joining stainless steel to carbon steel. (Also available
in composite form, as Weld Mold? 4182-C.)
Specification: AWS-ENiCrFe-3
Available forms: E , FC , TIG , MIG
¡¡
Weld Mold®4187 (DC-RP) - Used for welding
wrought or cast 70/30, 80/20 and 90/10 copper/nickel
alloys. Dissimilar-welding applications include welding
Monel¢ç alloys and Nickel 200 to copper/nickel alloys.
Specification: AWS-ECuNi
Available forms: E , TIG , MIG
¡¡
Weld Mold¢ç 4190 (DC-RP) - For welding of
Monel¢ç alloys 400 and 404 to themselves or each other
and for overlaying on steel. Dissimilar-welding
applications include joints between Monel¢ç alloys and
carbon steel, low-alloy steel, copper, and
copper/nickel. (Also available in composite form, as in
Weld Mold¢ç 4190-C)
Specification: AWS-ENiCu-7
Available forms: E , TIG , MIG
¡¡
Polymatic¢ç 4625 (DC-RP) - Used primarily to
weld Inconel¢ç 625 and 601, Incoloy¢ç 800 and 802 and 9%
nickel steel. Usurpassed as a wear-resistant overlay on
hot-work tools such as extrusion dies.
Specification: AWS-ENiCrMo-3
Available forms: E , FC , TIG , MIG
¡¡
Weld Mold¢ç 4637 (DC-RP) - For joining and
particularly for the overlay of Udimet¢ç alloys 500 and
520. It has high resistance to high temperatures and
impact and maintains high strength and toughness at
elevated temperatures. Primarily used for repair and
reclamation of rapid-blow rotary forge dies. Also used
for build-up and repair of Waspaloy.¢ç
Rc 30-35 as-welded, work-hardens to Rc 45+
Specification: DIN 2.4976
Available forms: E , FC
¡¡
Polymatic¢ç 4638 (DC-RP) - Used for
hard-facing buildup of hot-working tools. Excellent for
underlay before deposition of hard-facing or overlay
alloys such as 4637.
Rc 20-24 as-welded, work-hardens to Rc 40-44
Specification: AWS-ENiCrMo-5
Available forms: E , FC
¡¡
Weld Mold¢ç 4718-C (DC-RP) - For welding
Inconel¢ç alloys 718, 706, and X-750. Uses include
joining and overlays on forging pres dies, H.I.P. dies,
cryogenic equipment and high-strength aircraft
components.
Specification: AMS-5832
Available forms: E , FC , TIG , MIG
¡¡
Weld Mold¢ç 4000-A (DC-RP) - Typical
applications are joining Inconel¢ç alloys to carbon
steel, stainless steel, Nickel 200, Monel¢ç alloys and
copper-nickel alloys, and joining Nickel 200, Monel
alloys and carbon steel to stainless steel. This alloy
is also used for joining Incoloy¢ç alloy 800 and 9%
nickel steel to themselves.
Specification: AWS-ENiCrFe-2
Available forms: E , FC
¡¡
Weld Mold¢ç 4000-B (AC) - Used for shielded
metal-arc welding of 9% nickel steel. It is similar to
4000-A except it is designed for use with AC current
only where magnetic forces (arc blow) are a problem.
Specification: AWS-ENiCrFe-4
Available forms: E , FC
¡¡
Weld Mold¢ç 4112-C (DC-RP) - For welding of
Inconel¢ç alloys 625 and 601 and Incoloy¢ç alloys 800 and
801. Also for overlays on carbon steel.
Dissimilar-welding applications include joining Incoloy¢ç
alloy 825 to stainless steels, carbon steel and
low-alloy steels; joining Inconel¢ç alloy 625, Monel?
alloy K-500 and Incoloy? alloys 800 and 825 to Inconel¢ç
alloys 706, 718, and X-750; and joining Incoloy¢ç alloy
800 to Incoloy¢ç alloy 825.
Specification: AWS-ENiCrMo-3
