QUIZA, Ramón; RIVAS, Marcelino; REYES, Diamela  y  CRUZ, Yarens. Free software application for designing manual arc welding technologies. Rev cuba cienc informat [online]. 2019, vol.13, n.1, pp. 76-89. ISSN 2227-1899.

Computerization of manufacturing processes is a demanding need for updating the Cuban mechanical industry. This work describes the implementation of an application for designing shielded metal arc welding technologies of steels. It simplifies selecting the standardized joint preparations and the electrodes to be used, and computing the welding parameters, process time and costs. The application has a customizable database, for marking straightforward the input of material and welding machine data. It also allows stating the auxiliary equipment and word-based technological requirements. The computer aided designed technology is presented as a welding procedure specification, accomplishing the ASME standards. The application has been implemented as open code and free software, by a strict use of development tools distributed under these conditions. It is also multi-platform and can be executed either on Linux or on MS Windows. Preliminary tests, which were carried out in three manufacturing enterprises, have shown a significant saving in time consumption for technology design and improvements in the outcomes quality and traceability.

Palabras clave : free software; welding; technology.
