Welding Wire STANLEY 637 DC / AC

Specification of

One of a kind heavily copper clad “ Tri-metal “ cored cast iron electrode.

· Visually unique core wire creates immediate customer interest.

· High efficiency weld metal transfer totally eliminates electrode overheating.

· Proprietary copper-nickel-iron deposit chemistry yields the ultimate

combination of softness, ductility and tensile strength.

TYPICAL MECHANICAL PROPERTIES

Undiluted Weld Metal Maximum Value Up to:

Tensile strength 77,000 Psi ( 550 MPa )

Yield strength 54,000 Psi ( 380 MPa )

Elongation 30 %

Impact energy Rockwell B 84-88 Brinell 176

Hardness Vickers 185

APPLICATIONS

The high deposition rate of this electrode creates an extremely narrow heat affected zone.

This feature is suitable for all weldable cast irons that require post weld machining.

MICROSTRURE

Consists of an iron-nickel-copper austenite with finely distributed graphite.

RECOMMENDED CURRENT

DC Reverse (+) or AC

WELDING POSITIONS

Flat, Horizontal, Vertical up, Overhead.

WELDING TECHNIQUES

Guide the electrode at a steep angle keeping the arc length short. Use short staggered beads when welding restrained parts.
