EutecTrode-670E

A High Alloy Content Electrode for Welding Steels of Unknown Composition and Dissimilar Steels

EutecTrode 670E ®

WELDING • Fully Austenitic structure helps retain mechanical properties • Great corrosion and spalling resistances up to 1800°F • Excellent in Salt-rich environments

DESCRIPTION:

WELDING PARAMETERS:

EutecTrode 670E has been specially formulated to meet the critical metallurgical demands when joining stainless and mild steels of unknown composition. Its composition also makes it an ideal candidate product when welding dissimilar steels and when such steels need scaling resistance up to 1800°F.

Preparation: Clean weld area of scale and/or oxide. Angle prepping normally involves close-butts and infrequently bevel preparations. If needed, a 60° bevel is acceptable.

Preheat and inter-pass temperatures will depend on the grade of steel, if known. Unknown grades should be nominally preheated within a 200-300°F range.

TYPICAL APPLICATIONS:

Technique: A short, non-contact technique is recommended for both fillet and butt welding. Use a slightly longer arclength for bead-on-plate welding. Deposit stringer beads or 2x to 3x weave beads. Do not weave more than three times the electrode diameter otherwise slag interference will be encountered.

Use in marine applications such as salt-water discharge pumps, desalination equipment, furnace baskets that work in both carburizing and reducing environments, salt baths used in drawing and tempering operations

TECHNICAL DATA: Typical Tensile Strength: 95,000 psi (655 N/mm2) Typical Yield Strength: 65,000 psi (448 N/mm2) Typical Elongation (1=5d): min. 25% Hardness as-deposited (HRB): 85 Maximum Temperature: 1800°F steady-state Current & Polarity: DCEP (+) and AC

Post-welding: Parts which have been preheated should be wrapped or covered with heat – retardant material to help with slow cooling.

Recommended Amperages Diameter:

3/32” (2.4mm)

1/8” (3.2mm)

5/32” (4.0mm)

Amperage:

50-70

70-110

110-150

Note: for optimum results use the lowest amperage practical

WARNING Protect yourself and others. Read and understand this warning. THIS PRODUCT CONTAINS CHROMIUM AND/OR NICKEL which are listed by OSHA, NTP, or IARC as being a carcinogen or potential carcinogen. Use of this product may expose you or others to fumes and gases at levels exceeding those established by the American Conference of Governmental Industrial Hygienists (ACGIH) or the Occupational Safety and Health Administration (OSHA). READ AND COMPLY WITH THE OSHA PERMISSIBLE EXPOSURE LIMITS FOR HEXAVALENT CHROMIUM (CrVi), Fed. Reg. 71-10099.

MANGANESE & RELATED COMPOUNDS SUCH AS MANGANESE DIOXIDE: Overexposure to manganese and its compounds may cause metal fume fever characterized by chills, fever, upset stomach, vomiting, irritation of the throat and aching of the body. Excessive overexposure may affect the central nervous system. Symptoms may include muscular weak ness and tremors.

Behavioral changes and changes in handwriting may also appear. Workers exposed to manganese and its compounds should receive quarterly medical examinations of early detection of manganese poisoning. FUMES AND GASES can be dangerous to your health. Certain medical studies have suggested that NERVOUS SYSTEM and/or LUNG DAMAGE can result from exposure to welding fumes and gases through the use of some electrodes. ARC RAYS can injure eyes and burn skin. ELECTRIC SHOCK can kill. • Before use, read and understand the Material Safety Data Sheets (MSDS), the manufacturer’s instructions, and follow your employer’s safety practices • Keep your head out of the fumes. • Use enough ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the general area. Respirators may be needed and should be chosen by the employer based on workplace conditions and contaminant levels.

For information regarding a respiratory protection program, see OSHA 1910.134 requirements. • Wear correct eye, ear, and body protection. • Do not touch live electrical parts. • In case of medical emergency, call for medical aid. •See American National Standard Z49.1, Safety in Welding and Cutting, published by the American Welding Society, 550 N.W. LeJeune Road, Miami, FL 33135; and OSHA Safety and Health Standards, 29CFR 1910, available from the U.S. Government Printing Office, Superintendent of Documents, P.O.
