Description
X-ray quality welds, smooth-running in all positions for joining the most common grades of stainless steels including 303, 304, 307, 308, 309, 316, 317 and the low carbon “L” version of these alloys.
Superior Advantages
• Minimal carbide precipitation
• Excellent resistance to corrosion and heat
• All-position welding reduces the need to dismantle equipment
• Easy slag removal saves time
Superior Vertical-down Performance
Tensile Strength: 80,000 PSI
Yield Strength: 56,000 PSI
Elongation: 42%
Polarity: AC or DC Reverse
Applications
• Piping and tubing
• Food and medical processing equipment
• Housings and impellers
• Tanks and vats
Usage Procedure
Use AC or DC reverse polarity with normal maintenance welding procedures. Surface area should be clean and dry, however, CERTANIUM 777 is manufactured with special cleansing and fluxing agents to promote sound welds under most conditions. For vertical-down welding, hold a short arc and tilt the electrode 10° in the direction of travel, using a stringer bead technique.
