North America’s Largest Fleet of Welding and Positioning Equipment WELDING ELECTRODE CLASSIFICATIONS MILD STEEL COATED ELECTRODES E7018-X E Indicates that this is an electrode 70 Indicates how strong this electrode is when welded. Measured in thousands of pounds per square inch. 1 Indicates in what welding positions it can be used. The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) covers all aspects of design and manufacture of boilers and pressure vessels. All sections contain welding specifications, however most relevant information is contained in the following: American Welding Society (AWS) Standards. ERNiCr-3 is used for Gas Tungsten Arc Welding (GTAW), Gas Metal Arc Welding (GMAW) and Submerged Arc Welding (SAW) of Inconel 600, Inconel 601 and Inconel 690, Incoloy 800 and Incoloy 800HT. Dissimilar welding applications include joining Inconel alloys, Incoloy alloys and Incoloy 330 to nickel, Monel alloys, stainless steels and carbon steels.

Preheat / Interpass Recommendations
Preheating copper – base alloys is frequently unnecessary provided section thicknesses are not unusually heavy.
Preheat and Interpass temperatures will vary depending on section thickness, selected weld process and other variables.
