Step 7 · Apply Solder to the Joint

Once the fitting is hot enough to melt solder, remove the flame and immediately touch the tip of the solder to the seam where the pipe enters the fitting. Touch it to the bottom of the joint first if it's horizontal, then work your way up and around. Capillary action will pull the molten solder into the narrow gap between the pipe and fitting. You only need to feed about 1/2-inch of solder for a 1/2-inch joint. You will see a silver ring appear as the solder fills the joint. Once this ring is complete, the joint is filled. Remove the solder and let the joint cool.
