Spot welding is used, among other things, for welding cooker hoods and the like, where it is not possible to add a weld. Following welding it is not necessary to polish the item, which makes spot welding an economical welding method.
Spot welding is well-suited for thin plate welding and for welding nuts onto plate parts.
Full welding is used for items which require a long duration or surface treatment using hot galvanisation or electroplating. Full welding prevents acid extraction during surface treatment.
