CARBON STEEL Covered Arc Welding Electrodes E7018

Descripción del producto

E***8 is a low-hydrogen iron powder type electrode that produces high quality X-ray welds. It can be used in all positions on AC or DC reverse polarity welding current. E***8 is recommended for welding medium grade carbon steels, where no preheat is used, and on cold rolled steels normally exhibiting excessive porosity when welded with conventional electrodes. Typical Applications: • Low-alloy structures • Low, medium, and high-carbon steels • Offshore rigs and power plants • Steel structures • Tack welds for tubular wire applications AWS Specification: AWS A5.1 AWS Classification: E***8 Welding Current: AC – DC EN (Electrode Negative) Typical Wire Chemistry: C: 0.**1 Mn: 1.*2 Si: 0.*3 P: 0.**4 Typical Mechanical Properties: Yield Strength, Mpa: ≥**0 Tensile Strength, Mpa: ≥**0 % Elongation: *0 Welding Positions: All positions Available Diameters: 2.5mm, 3.2mm, 4.0mm & 5.0mm
