Maintenance & Repair Electrode for Contaminated Steels
SteelTectic N ®
WELDING • Welds on steels that are rusty, dirty or heavily scaled • Easily controlled for continuous welding • Can be used over a wide amperage range • Excellent for poor or irregular fit-ups
DESCRIPTION:
WELDING PARAMETERS:
SteelTectic N is an all-position electrode recommended for welding dirty, rusty, contaminated and heavily mill-scaled steels. The deeply penetrating arc effectively cuts through surface contamination and provides a sound weld.
Preparation: Remove excessive scale. Weld joints typically do not need to be beveled. Preheating is generally not required on mild and plain steels, however is recommended to drive off moisture, for parts over 1” thick or highly restrained joints.
SteelTectic N will provide a solid weld base on “dirty“ parts where a more sensitive electrode can be used to complete the weld. The arc is easily controlled which aids in non-stop welding. Poor fit-up assemblies can be easily repaired at lower amperages. SteelTectic N can be used on mild and plain carbon steels.
Technique: A “contact technique“ is recommended for fillet welding and a reasonably small arc-gap is recommended for flat, bead-on-plate welding. Deposit using stringers or by weaving (2x - 3x). Weaving more than 3x the electrode diameter is not recommended in order to avoid slag inclusions.
