Larry Potterfield, CEO and Founder of MidwayUSA, teaches the process of using TIG welding to repair broken gun parts. TIG, or tungsten inert gas, welding is an arc welding process that uses a tungsten electrode to produce the weld. Argon gas is used to protect the work piece from contamination. This process allows precise control over the size of the weld, and the temperature of the metal. For people looking for a very basic introduction to how TIG welding can be used to repair small gun parts, this video is the answer.
