Description
ESAB 7018-1 Prime is a reliable, high-quality electrode, providing high deposition rate and extra low moisture absorption. It provides excellent welding pool control, minimal spatter level, good arc strike and easy slag removal making it easy to weld with, including in out-of-position welding. Particularly suitable for welding high strength low-alloy steels. The low-temperature impact strength of the weld metal should be noted.
The prevention of hydrogen induced cracking in thick structural steels or porosity in stainless or nickel-base weld metal, by controlling the moisture re-absorption in the coating of low hydrogen electrodes, can be very costly. In demanding applications, such as offshore fabrication, the cost of climate controlled storage and handling and the associated administrations are often calculated to exceed the cost of the consumables itself. With ESAB 7018-1 Prime VacPac vacuum packaging, these costs are completely avoided.
