Welding consumables refer to the materials and supplies used during welding processes to create a strong and durable joint between two or more metal pieces. These consumables are essential components of the welding process and are chosen based on the specific welding method, type of metal being joined, and the desired weld quality.

The selection of welding consumables is crucial to achieve welds with the desired strength, integrity, and properties. Welders must carefully consider factors such as base metal composition, welding method, joint design, and the application's requirements to choose the appropriate consumables for a successful welding operation.
