Welding is a process used to join two or more pieces of metal together by melting them at their edges and allowing them to cool and fuse. This technique is commonly used in construction, manufacturing, and repair work. Different methods of welding, such as MIG welding, TIG welding, and stick welding, utilize various tools and techniques to achieve strong, durable bonds. Welders use equipment like welding machines, protective gear, and filler materials to complete their tasks safely and effectively. The quality of a weld depends on factors such as the type of metal, the welding technique, and the skill of the welder. Proper training and safety precautions are essential in this field.
