A

Take a NEAR WELDING heat on the middle of the piece which forms the top of the T. Upset to 1^1/2" times the thickness with extra metal on one edge of the bar to form a bulge like this -

B

Take a fresh heat and draw this side bulge into a lip with a blunt edge about ^3/16" thick as shown here -

C

Take a NEAR WELDING heat and split this lip down the middle with a hot chisel to form a semi-circular pocket to receive the fan-shaped scarf on the piece which will be welded in.

Lay on the side of the fire to retain the heat while the next piece is being prepared.

D

Take a NEAR WELDING heat on the end of the piece which will form the leg of the T and upset it for about ^1/2"

Forge the upset into a fan-shaped chisel end, drawing as much metal as possible to the sides, like this -

E

Take a BRIGHT RED heat and drive the chisel end hard down into the pocket, making sure that it reaches the bottom before closing in the lips, thus -

Lay both pieces side by side in the fire. To prevent burning the thin edges of the pocketed piece it must stand on edge with the lips upwards.

F

Take a FULL WELDING heat and start the weld by driving the short end right down to the bottom of the pocket.

Concentrate on getting the full width of the fan solidly welded into the bottom and ends of the pocket, leaving the lips till the next heat.

G

Take another FULL WELDING heat and complete the weld by closing in the lips, leaving a small radius in the corners of the T.
