all cases, a class of electrode should be called out
based on the table of matching filler metals in AWS
D1.1/D1.1M. If in special cases the selection of
the proper electrode is critical to the design, the
designer may specify the electrode to be used in
this or other sections. In special cases, it may
also be necessary to specify the welding process.
**************************************************************************
All welding equipment, electrodes, welding wire, and fluxes shall be
capable of producing satisfactory welds when used by a qualified welder or
welding operator performing qualified welding procedures. All welding
equipment and materials shall comply with the applicable requirements of
AWS D1.1/D1.1M.

NOTE: When the proposed shielded metal-arc welding
procedures are reviewed, the voltage and travel
speed should be within the limits shown in the

These limits are for 3.0 mm (1/8 inch) diameter
electrodes and the voltage will vary a small amount
(plus or minus 2 volts) with different diameters.
The travel speed limits will remain constant. The
current limits, which are based on coating types and
core wire diameter, should be as designated in AWS
A5.1/A5.1M. The heat input, measured in Joules per
mm (Joules per inch),
(Voltage x Current x 60)/(Travel speed inch/minute).
