Air Liquide Basic-Coated Electrodes, Low-Hydrogen, 3.2 mm (A0274398+X0010633)

Basic-Coated ElectrodesBlueShield™ Shielded-metal arc welding provide the best possible weld qualityPremium low hydrogen electrode for high-strength steels with toughness down to -45°CLeader in the Canadian market, the BlueShield line meets high-quality standardsEasy to use, low spatter, with excellent appearanceFor boiler and pressure vessel work, structural fabrication, pressure piping, maintenanceThe low volume hydrogen diffusion from the weld deposit considerably reduces the tendency to underbead (cold) crackingIdeal for boiler and pressure vessel work, structural fabrication, and moreAllows welding of ""difficult-to-weld"" steels with less preheat requirements than is required for non-basic type electrodesEnables code quality welds (X-ray clear) with proper welding proceduresOperates with DC current electrode positive or ACAllows for stringer bead or weaving techniqueMaintain the shortest arc possible for the best mechanical propertiesMinimize porosity by striking the electrode ahead of the crater of the previously finished weld bead and quickly move back into the crater while reducing the arc length
