Submerged Arc Flux/Wire
Lincolnweld ® submerged arc electrode and
flux combinations come with certificates of conformance.
To access these certificates,
follow the directions below.
1. Go to the Lincoln Electric home page at
www.lincolnelectric.com.
2. Click on the ‘Support’ tab and select ‘Certificate
Center’ from the drop down. (Image 1)
3. Under ‘Certificates of Conformance,’ you can choose
a Product or a Flux Combination. This will bring up
the most recent Certificate of Conformance.

How to look for flux/wire combinations that
meet your required mechanical properties:
Tensile Strength
1. In the second box under ‘Certificates of Conformance,’
you can ‘Search by Name/ Cert # / Classification.’
2. Enter F#P or F#A. Where # is 10X the required
Tensile Strength in ksi. P= Stress Relieved,
A= As-Welded.
a. For example, entering F7P would mean you are
looking for a flux/wire combination with 70 ksi
Tensile Strength in the Stress Relieved Condition.
Impact Requirements
1. In the list of matches for your required Tensile
Strength, you can see which Flux/Wire Combinations
also meet your Impact Property Requirements.
2. If you need to meet Impact Requirements at a
certain value, note that the digit following the “A” or
“P” in the classifications shows the temperature at
which the weld metal achieves a minimum of 27 J
(20 ft•lbf).
a. For example, a classification beginning with
F7P2 would mean that the flux/wire combination
meets 70 ksi Tensile Strength in the Stress
Relieved Condition and Impact Requirements
of 27 J (20 ft•lbf) @ -29°C (-20°F).

Selecting Flux/Wire Combinations
Guidelines for Selecting a Submerged Arc Flux/Wire Combination
In general, if you are familiar with one of the listed
fluxes, you might want to choose that option. From
an operator’s standpoint, it is easier to change
electrodes than to reset procedures for a new flux.
If you are welding high strength or highly
restrained steel, you might want to choose a Flux/
Wire Combination with a lower diffusible hydrogen
level, which is designated by the number following
-H in the flux/wire classification.
If you have limits on the compositions of the
electrode or the weld metal, click on a Flux/Wire
Combination to see the test results. Remember
that these results represent undiluted weld metal
from a standardized test and may be different
from your application, especially if variations in
base metal, heat input or pass sequence are
present.
