_Making a corner plate:_ This corner plate shows two pieces of metal,
1/4 × 1 × 6 ins. welded in the corners, upset. The ends of the pieces
to be joined are scarfed as explained in the flat weld. Both pieces
are heated, then one placed on the other, driven down, and welded. They
are shaped upon the edge of the anvil, and the ends are cut off to the
length shown by the drawing.
[Illustration: T Weld]
_T weld:_ This is used in making a T plate. The cross piece is upset in
the middle and scarfed by using the peen of the hammer as shown.
The upright piece is upset on the end and scarfed, same as was done
on the corner weld. Both pieces prepared are then heated and welded
as described in the making of the corner plate. The sketch given here
shows fairly well the different steps.
