When the preceding joint is well mastered and a number of good joints have been wiped, turn the pipe on an angle of 45°; to the left.

Preparation

The preparation for this joint is exactly the same as for the horizontal joint. The beginner should turn back and read carefully concerning the perfection of the joint. Bear in mind that the pipe must be correctly prepared or a good joint cannot be made. The edge of the paper must be cut not torn.

Placing Pipe In Position

This pipe can be placed in position the same as the preceding one. If heavy weights are placed on the ends of the pipe, a bad habit may be formed by the one learning to wipe. That is, the habit of pressing hard on the joint when wiping. In the preceding joint, if the beginner presses too hard, the pipe will fall off the bricks.

Wiping

Proceed as described for previous joints. The top edge must be favored a little. The hot solder will run down to the bottom edge; therefore less solder should be dropped on it than on the top edge. When the solder is at the proper heat for wiping it requires only a light touch to wipe the joint. If it appears necessary to press hard on the joint to wipe off surplus solder, it shows that the solder is not at the correct wiping heat.
