ESAB 7018-1 PRIME 5/32"X14" - Firepower

Specifications

The ESAB 7018-1 PRIME 5/32"X14" electrode is an AWS E7018-1 H4R classified low-hydrogen, iron powder type stick electrode. This designation indicates a minimum tensile strength of 70,000 psi (480 MPa) and improved impact properties at low temperatures. It is suitable for use with both DC+ (Direct Current Electrode Positive) and AC (Alternating Current) welding currents. The electrode measures 5/32 inches in diameter and 14 inches in length. Each master carton of these electrodes weighs 24 lbs. This specific model is identified by the manufacturer's part number 55044030G0.

Key Features

The ESAB 7018-1 PRIME electrode features a specialized low-hydrogen basic coating designed for high-quality welds. Its iron powder composition ensures a high deposition rate and extra low moisture absorption, contributing to enhanced weld integrity. The electrode provides excellent welding pool control, minimal spatter, a smooth, stable arc, and easy slag removal, which collectively improve welder appeal and efficiency. A graphite coating on the electrode tip facilitates easy arc initiation, helping to minimize porosity at the weld start. This product is often supplied in ESAB's VacPac™ vacuum-sealed packaging, which guarantees 100% hermetic sealing to keep electrodes in pristine condition until opened, eliminating the need for re-baking, holding ovens, or quivers.

Applications

The ESAB 7018-1 PRIME 5/32"X14" electrode is primarily used for welding 490 MPa (70 ksi) high-tensile strength steels. It is well-suited for demanding applications requiring high fracture toughness and stringent X-ray quality, especially at temperatures down to -45°C (-49°F). Typical applications include the fabrication of steel frames, bridges, and pressure vessels. It is also widely employed in structural steel welding, offshore construction, power generation, pipeline construction, and shipbuilding. The electrode's characteristics make it effective for welding medium-grade carbon steels, particularly where preheating is not used or where cold-rolled steels might otherwise exhibit excessive porosity with conventional electrodes. It performs effectively in all welding positions, with the exception of vertical-down.

Benefits

Using the ESAB 7018-1 PRIME 5/32"X14" electrode offers several tangible advantages. Its low-hydrogen properties significantly reduce the risk of hydrogen-induced cracking in thick structural steels and prevent porosity in stainless or nickel-base weld metal, ensuring superior weld quality and reliability. The innovative VacPac™ packaging eliminates the need for costly climate-controlled storage, re-baking, or specialized holding equipment, leading to substantial cost savings and simplified handling. This allows for safe welding immediately after opening the package, guaranteeing consistent performance without delays. Welders benefit from excellent mechanical properties, including high ductility and toughness, even in low-temperature environments. The electrode's ability to operate at lower than normal currents while achieving a fully penetrating weld bead is particularly beneficial for inaccessible root runs, enhancing operational flexibility. Its high deposition rate and excellent operator appeal allow for faster welding without sacrificing out-of-position performance.
