Welding is a manufacturing method that involves joining two or more pieces of metal together using various techniques such as arc welding, resistance welding, or laser welding. Skilled welders use heat and pressure to melt and fuse the metal at the joint, creating a strong and durable bond. Welding plays a critical role in industries such as construction, automotive, aerospace, and manufacturing, enabling the fabrication of structures, machinery, and components. It requires expertise in welding processes, metallurgy, and quality control to ensure proper weld penetration, strength, and adherence to industry standards. Precise control of welding parameters and inspection techniques are essential to ensure the integrity and safety of welded structures.
