What is stick welding?

Stick welding is a manual arc welding process, also known as shielded metal arc welding (SMAW). The process uses an electrode coated in flux that melts to form the weld pool and protect it from oxidation and other contaminants. Stick welding is commonly used for welding carbon steel, stainless steel, and cast iron, and it is suitable for welding in outdoor and remote areas.

Stick welding requires the use of a welding machine with a constant current power source and a welding electrode holder or clamp. The electrode is struck against the workpiece to start the arc, and the welder maintains the arc length and angle to control the heat input and deposition rate. As the welding progresses, the electrode melts and the flux forms a slag layer that covers the weld bead and protects it from the atmosphere.

Stick welding is versatile, relatively simple and inexpensive compared to other welding techniques, but it requires skill and experience to produce high-quality welds. Some of the factors that can affect the quality of a stick weld are the type and thickness of the base metal, the composition and size of the electrode, the welding position, and the welding technique. Stick welding is widely used in construction, fabrication, repair, and maintenance applications.
