HOBART
Pertanyaan yang Sering Diajukan
Pertanyaan umum tentang HOBART dari 3G Electric.
What are the typical tensile strength ranges for HOBART stick electrodes like the E7018 H8?
HOBART stick electrodes, such as the E7018 H8 carbon steel electrode (SKU 54JK78), are specified with a tensile strength of 88 ksi and a yield strength of 77 ksi as welded. These values are typical for low-hydrogen electrodes used in structural steel fabrication where high strength and crack resistance are required. The H8 designation indicates a controlled hydrogen content below 8 mL per 100 g of deposited weld metal, which reduces the risk of hydrogen-induced cracking in restrained joints.
What AWS classifications are available for HOBART MIG welding wires?
HOBART MIG welding wires are available in several AWS classifications, including ER70S-6 for carbon steel (SKU 6ETL3), ER5356 for aluminum (SKU 6ETN6), and ER308/308L for stainless steel (SKU 54JK70). The ER70S-6 wire offers a tensile strength of 70 ksi and yield strength of 58 ksi, suitable for general fabrication. ER5356 provides a tensile strength of 38 ksi for aluminum alloys. ER308/308L delivers a tensile strength of 85 ksi and yield strength of 59 ksi for welding 304 and 308 stainless steels.
What is the application of HOBART E309L stick electrodes?
HOBART E309L stick electrodes (SKU 33M411) are classified as E309/309L-16, designed for welding stainless steels and for joining carbon steel to stainless steel. The low carbon content (L grade) minimizes carbide precipitation in the heat-affected zone, improving corrosion resistance. These electrodes have a tensile strength of 79 ksi and yield strength of 56 ksi as welded. They are commonly used in chemical processing, food equipment, and other applications requiring corrosion-resistant welds.
What brazing alloys does HOBART offer?
HOBART offers nickel-silver brazing alloys, such as the RBCuZn-D composition (SKU 6ETP5), supplied as bare sticks measuring 3/32 in x 36 in. This alloy has a tensile strength of 70 ksi and is used for brazing steel, copper, and nickel alloys. It is suitable for applications requiring good corrosion resistance and color match, such as in plumbing, HVAC, and decorative metalwork. The alloy contains no silver, making it a cost-effective option for brazing joints.
What replacement parts for band saws does HOBART supply?
HOBART supplies replacement parts for band saws, including cylinder wrenches (SKU 235A78, part number 00-290885) and shaft seals (SKU 235A76, part number 00-290844-00001). The cylinder wrench is a knob-type tool used for adjusting or replacing band saw blades. The shaft seal is a blade guide component that helps maintain proper blade alignment and reduces wear. These parts are designed to fit specific HOBART band saw models and are available through 3G Electric for maintenance and repair.
What spool types are available for HOBART MIG welding wire?
HOBART MIG welding wires are supplied on various spool types depending on the product. For example, the ER70S-6 carbon steel wire (SKU 6ETL3) comes on an 11 lb plastic spool, while the ER5356 aluminum wire (SKU 6ETN6) is on a 1 lb spool. Plastic spools are lightweight and resistant to corrosion, making them suitable for storage and handling. Spool sizes and materials are selected to match the wire diameter and application, ensuring smooth feeding in MIG welding guns.
