Weld

Welding is a process of joining two or more pieces of metal or thermoplastics by applying heat, pressure, or both, to create a strong, permanent bond. The heat melts the materials at the connection point, and when cooled, they fuse together. Welding is commonly used in construction, manufacturing, and repairs to build everything from bridges and cars to pipelines. The quality of a weld depends on proper technique, materials, and conditions, ensuring the joint is durable and able to withstand stress or environmental factors.
