length of undercut of an arc spot weld of 1
inch diameter (25 mm) is
10. Reference is made to a CJP Groove 10 ksi less than matching

metal tensile strength required for this
application?
11. For a welded built-up beam with a 10 +/- 1/8; D1.1 5.23.9

or dried under what conditions? 5.3.3.2
13. Nondestructive testing is required on a At least 1 in a 4"; D1.1
particular long complete penetration 6.15.3
groove weld in a welded subassembly.

sufficient. What is the minimum length of
each spot test?

What is the effective area of a 1 inches
thick complete penetration groove weld
that is 6 inches long?
15. For a flare-V groove weld between 4" - what is specified; D1.4
two reinforcing bars specified to be 4 2.3.2.2
inches (100 mm) in length, what is the
acceptable length?
16. A 5/16 inch fillet weld is used to 1-7/8 sq.in; D1.4 2.3
connect two 1/2 inch steel plates in a "T"
configuration. The fillet weld is 6 inches
in length. What is the effective area of this
fillet weld?
17. The size of a 5/16 inch. fillet weld may 1/8"; D1.1 T6.1(6)
be less than the specified nominal size by
______ without correction provided the
undersized portion does not exceed 10
percent of the weld length.
18. What is the name of the welding ESW; D1.1 Annex K
process that produces coalescence of metals with
molten slag that melts the
filler metal and the surfaces of the workpieces?
The weld pool is shielded by this
slag, which moves along the full cross
section of the joint as welding progresses.
The process is initiated by an arc that
heats the slag. The arc is then
extinguished by the conductive slag,
which is kept molten by its resistance to
