Electrodes

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). The word was coined by William Whewell at the request of the scientist Michael Faraday from two Greek words: elektron, meaning amber (from which the word electricity is derived), and hodos, a way.

E308-16 is designed for welding of the following 18-8 stainless steel types: 301, 302, 304 and 308. The weld deposit has the proper chemical content and balance for satisfactory welding of type 308, and therefore is suitable for welding 18-8 types of lower alloy content. Sound weld metal and corrosion resistance equal to or greater than that of the parent metal are assured.

A versatile, deep penetrating steel electrode with smooth, stable arc characteristics. It’s used for the welding of mild steels, galvanized and some low alloy steels. The coating produces a forceful, spray-type arc, resulting in deep penetrating welds. The slag is thin and easily removable.

Typical Application:  Vehicles, ship building and repair, sheet metal, build-up of over machined and worn mild steel surfaces, general light fabrication.

E6010 electrodes, one of the basics for pipe and plate stick welding, are old standbys that are easily handled by industrial transformer-type welding machines. But the new generation of portable inverter-type machines don’t always handle them well. An industry expert tells the 6010 story and explains what to look for in an inverter welder for this penetrating electrode.

A high deposition electrode for low and medium carbon steels. It is an efficient, iron powder, low hydrogen electrode with excellent mechanical properties; crack resistance; and X-ray quality welds. This electrode offers a quiet, stable, low penetration, spatter-free arc. The moderately heavy slag is easy to remove, revealing a bead with distinct ripples. Operator appeal is a plus factor.

Typical Application:  Ship hull construction, pressure vessels, boilers, piping, heavy duty equipment, general maintenance or production fabrication.
