What is a common name for the process characterized as stick welding?

Stick welding is colloquially known as arc welding because of the electric arc that forms between the welding electrode and the workpiece. This arc generates the heat necessary to melt the metal and fuse the materials together. The term "stick welding" specifically refers to the use of a consumable electrode, which is often referred to as a "stick" of filler metal coated in flux. This flux not only protects the weld from contaminants in the air but also helps to stabilize the arc.

Arc welding encompasses several processes, including stick welding, and is fundamental in various applications due to its versatility and effectiveness in joining metals. The other processes mentioned, such as semi-automatic welding, submerged arc welding, and gas metal arc welding, refer to different techniques or forms of welding that utilize various methods and equipment, making "arc welding" the most broadly applicable and correct term for the process in question.
