Thermal welding is a process that joins materials, typically metals or thermoplastics, by using heat to melt the edges of the pieces being joined. This method allows the materials to fuse together as they cool, creating a strong bond. It is commonly used in various industries, including construction and manufacturing, due to its efficiency and effectiveness. There are several techniques within thermal welding, such as arc welding, gas welding, and laser welding. Each technique utilizes different heat sources and methods to achieve the desired weld quality. Thermal welding is valued for its ability to create durable connections in a wide range of applications.
