Welding is a process used to join two or more pieces of metal or thermoplastic materials by heating them to a high temperature until they melt and fuse together. In metal welding, a filler material may be added to help fill gaps and strengthen the joint. Once the material cools and solidifies, it forms a strong, permanent bond. This technique is commonly used in construction, automotive repair, and manufacturing to create or repair metal and plastic structures and components.
