Not cleaning the pipe or joint enough, not using flux, or not heating the pipe or joint enough. You use the blue tip of the flame on the joint and the capillary action sucks the solder into the joint. You have to clean the pipe with sandpaper or steel wool, the joints with a fitting brush on the inside, and use a proper flux and solder.

There are a number of tools that a plumber should have while dealing with a leaky pipe. A screwdriver and a wrench are the most important, and a roll of tape never hurts.
