To provide all necessary torch movements, the robot must have four degrees of freedom: torch travel speed, stick\u2010out, torch angle and lateral motion. Thus, using a look\u2010up table\u2010which was specially designed to this application\u2010it is possible to follow the optimal parameters (voltage, current, welding speed, torch angle and stick\u2010out) for each welding position (flat, vertical and overhead).<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>The robotization of the orbital welding process brings enhancement in the final product quality, considerable increase of repeatability, reduction of rework and reduction of the weld execution time. At the very least, the robot is capable to reproduce the weld bead of the best human welder, through the use of the same paramenters contained in a table.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Practical implications<\/jats:title><jats:p>The use of this robot in welding with GMAW proved to be extremely viable. It was shown that the bead shape did not suffer great variations from one welding postion to another, thanks to the use of a gradual change of parameters.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>Although, by RIA definition the devices for the orbital welding shown in literature up to now are not robots, the developed device can be called a robot due to its capability of being completely programmable and automatically carrying through all welding activities.<\/jats:p><\/jats:sec>","DOI":"10.1108\/01439910510600182","type":"journal-article","created":{"date-parts":[[2005,6,28]],"date-time":"2005-06-28T03:19:29Z","timestamp":1119928769000},"page":"321-325","source":"Crossref","is-referenced-by-count":22,"title":["Development of a robot for orbital welding"],"prefix":"10.1108","volume":"32","author":[{"suffix":"II","given":"Eduardo J.","family":"Lima","sequence":"first","affiliation":[]},{"given":"Guilherme C.","family":"Fortunato Torres","sequence":"additional","affiliation":[]},{"given":"Ivanilza","family":"Felizardo","sequence":"additional","affiliation":[]},{"given":"Frederico A.","family":"Ramalho Filho","sequence":"additional","affiliation":[]},{"given":"Alexandre Q.","family":"Bracarense","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"key":"key2022030719580221400_b1","unstructured":"AWS (1991), Welding Handbook: Welding Processes, 8th ed., Vol. 2, American Welding Society, Miami, FL."},{"key":"key2022030719580221400_b2","unstructured":"Blackman, S.A. and Dorling, D.V.
