What is Slag in Welding, and How Does It Work? (2024 Guide)
This is why it is called 'submerged' arc welding since the arc is not visible outside of the flux. The slag formed is typically easy to remove. Image Credit: Greeneries, Shutterstock Electroslag Welding. Electroslag Welding (ESW) is a single-pass process designed for welding thick plates, typically greater than 1¼ inches of thickness.

Understanding Deoxidizers in Filler Metals
This action allows the filler metal to weld smoothly through mill scale or rust without compromising arc quality or welding performance, and without concern of inclusions in the completed weld. There are three primary elements that manufacturers use as deoxidizers: manganese, silicone and aluminum. Occasionally they also use titanium or zirconium.

Mill Scale
Take a piece of hot rolled steel plate or flat bar, ~8" long. Thoroughly grind 1/2 of the surface to remove all mill scale. Using a 1/8" E7018, at about 110 amps, make a simple weld bead, without weaving, starting on the unground end and finishing at the other end (ground end).

Frequently asked questions about hardfacing
Generally, these are iron-base alloys that contain high amounts of chromium (greater than 18 percent) and carbon (greater than 3 percent). These elements form hard carbides (chromium carbides) that resist abrasion. The deposits frequently check-crack about every 1/2 in., which helps relieve stress from welding.
