AXIS OF A WELD:
A line through the length of a weld, perpendicular to a cross section at
its center of gravity.
BACK FIRE:
The momentary burning back of a flame into the tip, followed by a
snap or pop, then immediate reappearance or burning out of the flame.
BACK PASS:
A pass made to deposit a back weld.
BACK UP:

BACKHAND WELDING:
A welding technique in which the flame is directed towards the

BACKING STRIP:
A piece of material used to retain molten metal at the root of the weld
and/or increase the thermal capacity of the joint so as to prevent

opposite to the direction of progress.
BARE ELECTRODE:
An arc welding electrode that has no coating other than that incidental
to the drawing of the wire.
BARE METAL-ARC WELDING:
An arc welding process in which fusion is obtained by heating with an
