Arc Welding electrodes are classified into a number of groups depending on their applica ons. There are a
great number of electrodes used for specialised industrial purposes which are not of par cular interest for
everyday general work. These include some low hydrogen types for high tensile steel, cellulose types for
welding large diameter pipes, etc. The range of electrodes dealt with in this publica on will cover the vast
majority of applica ons likely to be encountered; are all easy to use.
1. General Purpose “GP” E6013: This all-posi on electrode is used for maintenance and fabrica on.
Works well on mild steel, galvanized steel, sheet metal, steel tube and RHS. Its so arc has minimal
spa er, moderate penetra on and an easy-to-clean slag. Tolerant to dirty / rusty steel & poor fit up.
This is the most common type of electrode used for S ck welding.
2.
Hydrogen Controlled E701
8
: A “low-hydrogen” electrode commonly used for mild or high strength
steel, where the joint requires higher strength than regular "GP" electrodes, such as highly
restrained joints or components subject to higher load stress. Also used as a buffer layer prior to
hard facing. All
-Posi onal (except for ver cal down), easy striking & smooth running, with low
1. Cast Iron Ni-Cl (NCI): Suitable for joining all cast irons (Suitable for mehanite, alloy and malleable
cast iron) except white cast iron. Weld posi ons : flat, horizontal.
1. Stainless Steel 316L: Used for welding common 300 series stainless steels such as 301, 302, 304,
304L and 316L. All welding posi ons, excluding ver cal down. Very Smooth Running and Easy to
use.
2. Universal 312: Weld-all style electrodes for welding almost any steel or stainless-steel, including
dissimilar metals. Weld metal is very crack resistant. Commonly used for repair and maintenance
welding of unknown steels. All welding posi ons excluding ver cal down.
