Welding is the partial joining of two or more metals
by deposition; the welding methods used for body
maintenance and repair can be classified into the fol-
lowing methods.
FUSION WELDING
Fusion welding is a method of welding in which the
weld connection is made by forming or supplying the
weld metal at the part where the weld is to be made.
PRESSURE WELDING
Pressure welding is a method of welding in which the
weld connection is made by applying external pres-
sure while the part where the weld is to be made is in
a molten or semi-molten condition.
BRAZING
Brazing is a method of welding in which the weld
connection is made by supplying a filler metal (which
is molten at a temperature lower than the melting
temperature of the base metal) at the place where
the joining is to be made without melting the base
metal itself.
