What is spot welding?
The principle of spot welding is to use the principle of resistance heating to increase the temperature of the contact.
Welding
Welding is a method of joining metal materials together by heating them to their melting point. Welding typically uses welding wire or electrodes as filler material, which melts and coats the metal surfaces to be joined. The molten solder material and base material form a firm bond after cooling. Welding can be used to join dissimilar metals, as well as to repair and strengthen metal parts. Welding usually requires certain equipment and skills to carry out, so special training is required to operate it. Welding is used in a wide variety of industries, including automotive manufacturing, aerospace, construction and manufacturing, among others.
