28 Table
of Typical Welding Conditions The
tables of typical welding conditions are designated as a guide in selecting and
developing suitable welding
voltages, currents and speed.* Variations from the conditions given are certainly
permissible, and often
desirable because of the characteristics of a particular installation. It is recommended,
however, that the
edge preparations shown in the tables be followed quite accurately since slight
variations can considerably
affect the making of the welds and the results achieved with the selected welding
conditioning. The
table to be used may be determined from the “Index of Weld Tables,”
based on the type of material to be
welded, the quality requirements of the weld, the design or type of joint to be
used, and the method of backing
the weld. Page
8 should be consulted regarding backing methods. This
handbook does not contain physical test data on welds produced by submerged arc
welding. The booklet
“Materials for Submerged Arc Welding Carbon and Low Alloy Steels” Form
51-202, contains tensile strengths,
impact strength, hardness values, and other physical data on welds made with various
combinations of submerged arc flux
and ESAB welding wire. You can obtain a copy of Form 51-202 from
your ESAB representative.
This booklet should be consulted to
determine the best welding flux to use from a performance viewpoint for
the specific welding joints described
in the following tables. Fluxes
which are commonly used for specific joints are listed with each table. However,
Form 51-202 should be
used to determine the best flux as well as sizing for a particular welding application.
