Heat- and Corrosion-resistant Nickel and Nickel/Chrome Base Alloys
 


The Weld Mold® 4000 Series
 


Weld Mold® 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® 4182 (DC-RP) - Used for welding Inconel® 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® alloy 800 to carbon steel, stainless steel, Nickel 200 and Monel® alloy 400 to carbon steel; joining Monel® 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&reg4187 (DC-RP) - Used for welding wrought or cast 70/30, 80/20 and 90/10 copper/nickel alloys. Dissimilar-welding applications include welding Monel® alloys and Nickel 200 to copper/nickel alloys.

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

 


Weld Mold® 4190 (DC-RP) - For welding of Monel® alloys 400 and 404 to themselves or each other and for overlaying on steel. Dissimilar-welding applications include joints between Monel® alloys and carbon steel, low-alloy steel, copper, and copper/nickel. (Also available in composite form, as in Weld Mold® 4190-C)

Specification: AWS-ENiCu-7
Available forms: E , TIG , MIG

 


Polymatic® 4625 (DC-RP) - Used primarily to weld Inconel® 625 and 601, Incoloy® 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® 4637 (DC-RP) - For joining and particularly for the overlay of Udimet® 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.®

Rc 30-35 as-welded, work-hardens to Rc 45+
Specification: DIN 2.4976
Available forms: E , FC

 


Polymatic® 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® 4718-C (DC-RP) - For welding Inconel® 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® 4000-A (DC-RP) - Typical applications are joining Inconel® alloys to carbon steel, stainless steel, Nickel 200, Monel® 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® alloy 800 and 9% nickel steel to themselves.

Specification: AWS-ENiCrFe-2
Available forms: E , FC

 


Weld Mold® 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® 4112-C (DC-RP) - For welding of Inconel® alloys 625 and 601 and Incoloy® alloys 800 and 801. Also for overlays on carbon steel. Dissimilar-welding applications include joining Incoloy® alloy 825 to stainless steels, carbon steel and low-alloy steels; joining Inconel® alloy 625, Monel? alloy K-500 and Incoloy? alloys 800 and 825 to Inconel® alloys 706, 718, and X-750; and joining Incoloy® alloy 800 to Incoloy® alloy 825.

Specification: AWS-ENiCrMo-3
Available forms: E , FC

 


Weld Mold® 4132-C (DC-RP) - For joining Inconel® alloy 600 to itself and to Inconel? alloy 601.
