 alloy sections 250- 400F (except silicon, bronze).
TYPE BRAZING - ARC
Use medium arc gap. (NOTE USE GOOD
VENTILATION. Hold electrode 10-15 degrees off
NSN: 9GJ 3439-00-262-2739 (1/8x14)
perpendicular.)
9GD 3439-01-131-4934 (5/32X 14)
CHARACTERISTICS:
POSITION: Flat
Has rapid deposition rate. Deposit is a copper-base
alloy.
POLARITY: DC Reverse
Hardness: Deposited 130 BHN
RECOMMENDED AMPERAGES:
Work Hardens to 230 BHN
1/8 - 80 to 160
3/16 -130 to 250
Tensile Strength: 90,000 psig
USES:
Primary: For high-strength joints on cast iron, steel,
and copper alloys. For joints and dissimilar
combinations susceptible to cracking. Excellent for
overlaying surfaces subject to frictional wear and
corrosive attack by salt water.
Secondary: Can be used for joining stainless,
nickel, and nickel alloys.
PROCEDURES:
Bevel crack to 90 angle. Preheat heavy steel and
cast iron sections to 200F. Preheat heavy copper
1-15
