In stick welding, materials are welded when a filler metal is melted between them. TIG welding effectively welds materials with or without the use of filler metals.
Stick welding can be employed outdoors because rain will not affect the quality of the weld. Stick welding workloads do not necessarily have to be cleaned before any welding takes place. TIG welding should be employed only indoors on materials that have been thoroughly cleaned and are free of contaminants. Heat is pinpointed better in TIG welding, resulting in a more precise weld. With stick welding, only a few inches of material can be welded at a time because of the constant need to refill filler metal rods.
Both methods of welding can be used on a variety of applications. Stick welding is often used to repair bridges and piping but is also used to create metal art. TIG welding is used with but not restricted to titanium, aluminum, nickel alloys and copper alloys.
