Abstract
A method of manufacturing a tube bend of a metal comprises positioning a base ring in the range of the welding device, using the welding device to deposit a first section of metal on the ring, moving the ring and the welding device through an arc relatively to each other by substantially the thickness of the first section of metal and thereafter depositing a subsequent section over the first section and repeating the moving and the depositing until the desired section thickness is formed into a wall. The device includes means for mounting a plate for pivotal movement and a base ring mounted on the plate for movement therewith below a welding device arranged so that the welding device and the plate remove relatively through an arcuate path so that a series of sections of metal may be built up into a tube bend wall. The welding device advantageously includes an electrode feeder and the apparatus preferably includes a welding device to provide a plating along the side of the wall section which is built up.
