Wet low hydrogen electrodes should be:
A) rebaked 2 hours at 230 to 260 degrees C.
B) rebaked 24 hours at 120 degrees C.
C) discarded.
D) rebaked for 1 hour at 430 degrees C.
Give this one a try later!
D) rebaked for 1 hour at 430 degrees C.
Overlap is defined as:
A) a weld condition where the weld face or root surface is below the adjacent surface
of the base metal.
B) referred to by the non-standard term suck-back when the root pass is drawn up
when the hot (second) pass is made.
,C) the protrusion of weld metal beyond the weld toe or weld root.
D) refers to the profile of a fillet weld.
Give this one a try later!
C) the protrusion of weld metal beyond the weld toe or weld root.
Elongated or wormhole porosity is:
A) a form of porosity having a length greater than its width that lies approximately
parallel to the weld axis.
B) porosity lying approximately perpendicular to the weld face and may become a
significant leak path possibility.
C) a localized array of porosity having a random geometric distribution.
D) porosity distributed throughout the weld.
Give this one a try later!
A) a form of porosity having a length greater than its width that lies
approximately parallel to the weld axis.
Tungsten inclusions appear on radiographs as:
A) dark areas within weld
B) white areas within weld
C) dark round areas outside weld
D) similar to porosity
Give this one a try later!

Underfill is a ____________ weld condition.
A) fillet
B) groove
