The welding process is a method used to join materials, typically metals or thermoplastics, by applying heat, pressure, or both. This process melts the base materials and often adds a filler material to form a strong bond upon cooling. Various techniques, such as MIG welding, TIG welding, and stick welding, are employed depending on the materials and desired strength of the joint. Welding is widely used in industries like construction, automotive, and manufacturing. Safety precautions, including protective gear and proper ventilation, are essential to prevent hazards such as burns, fumes, and exposure to harmful gases during the welding process.
