Q2-5 How can you identify an individual low hydrogen electrode which a welder is already consuming to make a weld?
a. Read the classification numbers painted on the covering near the stub end of the
electrode.
b. Ask the welder what it is.
c. Ask the welding foreman. ,
d. Look at the completed weld and identify the type of electrode by the visual
appearance of the weld deposit.
e. Look on the drawing or specification to determine what type of electrode is required
for that weld.

Q2-6 How should low hydrogen electrodes be stored before use?

Q2-7 what joint fit should you insist on?
a. within tolerances specified on drawings or specifications
b. Groove welds should have minimal root openings to reduce distortion.
c. root openings greater than 1/8″ to assure complete penetration

b. in heated storage ovens
c. in open tool crib shelves
d. in individual welders’ electrode pouches
e. none of the above

Q2-10 How can a CWI verify that the specified material is used on the job?
