ESAB says its history of innovation began in 1904 when Oscar Kjellberg, a welding pioneer, submitted a hand written patent for the covered electrode. Kjellberg's invention was more than the introduction of a unique new product; it represented the beginning of the modern era in welding.
Furthermore this result suggested a Warburg-like mass transfer impedance occurring in the low frequency portion, which indicated that s-BLM after interaction was deficient to eliminate electron transfer between Fe[(CN).sub.6.up.4-/3-] and the covered electrode 23].
It occurs in gas-shielded metal-arc welding used active gases (MAG process), inert gases (MIG process) or manual welding by the covered electrodes (MMA process).
