What is the primary purpose of a welding torch?

The primary purpose of a welding torch is to heat and fuse metal. A welding torch generates a flame that reaches high temperatures, allowing the user to melt metal pieces together, creating a strong bond. This process is essential in many applications, such as metal fabrication, construction, and repair work. The welding torch not only provides the heat necessary for the fusing process but can also be used to add filler material to the joint, enhancing the strength and integrity of the weld. Overall, the ability to apply intense heat to metals is what defines the role of a welding torch in welding operations.
