Description

Tube supply apparatus The present invention relates to a tube supply device, and more specifically, to a tube supply device in which the supply of a tube to be welded is performed automatically. Welding is a method of joining two solid materials by forming direct interatomic bonds between them, and it is widely used to join metal materials. Generally, a welding device performs welding work along a welding line using a welding torch or the like while the workpiece is secured by being placed on a fixing jig that holds the workpiece. Meanwhile, tubes and fittings are applied as welding targets, and pipes of various shapes can be formed through the joining between them. Accordingly, conventionally, users manually selected tubes and fittings of various shapes and placed them on a fixed jig for welding to perform the welding. In particular, in the case of tubes, the manual supply of tubes formed in various lengths and sizes resulted in delays in preparation time for welding and a decrease in overall process efficiency. Furthermore, since welding is performed without a separate inspection procedure for the supplied tubes among tubes of various lengths and sizes from the time the tube is supplied until welding is carried out, there is a problem of deterioration in welding quality due to the supply and welding of tubes other than the intended tubes.
