Handheld welding is a versatile and widely-used method of joining materials together using heat and pressure. This process involves the use of a handheld welding tool, such as a welding torch or welding gun, to apply heat to the materials being joined in order to melt them and create a strong bond. Handheld welding is commonly used in a variety of industries, including construction, automotive, and manufacturing, for tasks such as metal fabrication, repairs, and maintenance. This method of welding offers flexibility, portability, and precision, making it a popular choice for many applications.
