As Mike finished up one of the notches, he became a little more aware of a steady hand and the placement of the weld. Here is a much better weld. As you can see, there is an equal amount of heat penetration throughout the weld, and the weld is equally distributed. A good technique for distributing the puddle across both parts being welded is to make curlicues or small letter C welds as you go. We found that this will give a much more desirable stacked-dime look to the weld. Aside from looking at the weld, you can tell a good weld from a bad weld by the way it sounds. You'll hear a continuous buzzing noise when making a good weld. A bad weld will make popping noises and a lot of sparks and sound very inconsistent.
