Metal Being Joined Electrode Comments
Mild Steel E6011 This electrode is used for all-position welding or for welding
on rusty, dirty, less-than-new metal. It has a deep, penetrating
arc and is often the first choice for repair or maintenance work.
Mild Steel E6013 This all-position, electrode is used for welding clean, new sheet
metal. Its soft arc has minimal spatter, moderate penetration and
an easy-to-clean slag.
Mild Steel E7014 All positional, ease to use electrode for use on thicker steel than
E6013. Especially suitable sheet metal lap joints and fillet welds,
general purpose plate welding.
Mild Steel E7018 A low-hydrogen, all-position electrode used when quality is an
issue or for hard-to-weld metals. It has the capability of producing
more uniform weld metal, which has better impact properties at
low temperatures.
Cast Iron Eni-Cl Suitable for joining all cast irons except white cast iron.
Stainless Steel E318L-16 High corrosion resistances. Ideal for dairy work etc.
Welding Position
The electrodes dealt with in this publication can be used in most positions, i.e. they are suitable for welding in
flat, horizontal, vertical and overhead positions. Numerous applications call for welds to be made in positions
intermediate between these. Some of the common types of welds are shown in Figures 4-5 through 4-12.
