CONTACT YOUR ELECTRODE MANUFACTURER FOR SPECIFIC INFORMATION INVOLVING
CRITICAL OPERATIONS.
Electrode coating should not be exposed to the rebaking temperature without first having been
reconditioned at a lower temperature. Failure to observe this rule will result in breakdown of
electrode coatings.
After rebake, lower temperature to
holding level
until reissue.
Note: In the HTS Stainless
electrode groups, and 15 &
16 type coatings, there can
e a greater difference in the
maximum temperature
requirements for rebaking
than those shown. This can
be handled by special
request to the particular
manufacturer involved.
b
IMPORTANT:
This table is offered as a
guide to proper storage
and oven holding
temperatures for the
most common
electrodes in use today.
In addition,
recondition/rebake
procedures for electrode
coatings that have been
exposed to moisture for
a sufficient period of
time to affect the weld
quality are included.
Good judgment and the
manufacturer’s
recommendations
should be your guide.
