Answer:
stick welding.
Step-by-step explanation:
The shielded metal arc welding (SMAW) process is commonly known as stick welding because it involves the use of a "stick" or electrode, which is a consumable metal rod coated with a flux that melts and forms a protective gas shield around the weld area. The electrode is held in an electrode holder, which is connected to the welding power source, and the electric arc is created between the electrode and the workpiece, causing the metal to melt and fuse together.
During the welding process, the flux coating on the electrode burns and releases gas, which helps to shield the weld area from the surrounding atmosphere. This protective gas shield prevents the molten metal from reacting with oxygen, nitrogen, and other gases in the air, which could weaken the weld or cause defects.
The stick welding process is widely used in construction, shipbuilding, pipeline welding, and repair work, as it is versatile, portable, and can be used in outdoor environments. The term "stick welding" has become a commonly used name for this welding process due to the use of the stick electrode.
