Superon E7016-1 H4 Welding Electrodes
Product Description
Superon E7016-1 H4 welding electrodes are high-quality, low-hydrogen electrodes designed for various welding applications. These electrodes are particularly suitable for welding structural steels, including mild and low-alloy steels. The E7016-1 designation indicates that these electrodes are capable of producing welds with a minimum yield strength of 70,000 psi and are classified as low-hydrogen, which helps in reducing the risk of hydrogen-induced cracking in the weld metal.
The coating on Superon E7016-1 electrodes is formulated to provide excellent arc stability, smooth operation, and minimal spatter. This makes them ideal for both flat and vertical welding positions. The electrodes are designed to be used with direct current (DC) and can also be used with alternating current (AC) under certain conditions. Their versatility and reliability make them a preferred choice among welders in various industries, including construction, shipbuilding, and manufacturing.
Uses
- Structural Steel Welding: Ideal for welding mild and low-alloy steels in construction and fabrication.
- Heavy Equipment Repair: Suitable for repairing heavy machinery and equipment due to their strong welds.
- Shipbuilding: Commonly used in the shipbuilding industry for its durability and resistance to cracking.
- General Fabrication: Effective for various general fabrication tasks where strong welds are required.
