Specification of Welding Wire STANLEY 637 DC / AC
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.
