Abstract
The advances in electronics and microcomputer technologies exert an important influence on the advances of welding technology and welding apparatuses. Top welding apparatuses make it possible to weld sheets and exacting materials such as stainless steel and aluminium, particularly due to adequate settings, control and regulation of indirect welding parameters (IVP) such as voltage, welding current, welding speed, type of electrode, wire feed speed, angle of welding electrode, welding current pulse shape, type of shielding gas, and other parameters. Control of numerous parameters, welding-current regulation, regulation of wire feed speed, selection of shielding gas, and a need for user-friendly setting of parameters of a welding apparatus are only some of the reasons for the application of high-performance computer technologies to welding apparatuses. The project will start from the latest findings in the field of welding technologies. Based on this, relevant hardware and software for controls realized as intelligent systems embedded in modern welding apparatuses will be proposed. An investigation will be conducted as to a possibility of functional upgrading of software of the system embedded in the apparatuses by a system of on-line monitoring of weld quality based on technologies of intelligent systems such as artificial neural networks, fuzzy systems, and genetic algorithms of optimisation. In the realization of software, advantages of the application of open source technologies will be studied. In the last phase of the project a prototype of the welding source with the embedded system for arc welding will be constructed. The development of modern welding apparatuses requires an interdisciplinary approach of experts on materials and welding technologies, experts on regulation technique, electronics and computer science.
Significance for science
Developed approaches and methods represent a significant contribution to the development of science, not only in the field of welding technologies, but also more broadly, as findings and results can be used in other research areas. The importance of research in science is presented with the development of new modelling and simulation methods, which are published in scientific and professional journals and presented at scientific and professional conferences.
Integrated research of two simulation models: the welding power sources based on PWM converter and dynamic models of short circuit gas metal arc welding process, allows new opportunities for the development of advanced welding power sources with appropriate digital controllers.
Developed measuring equipment and realised technological measurements allows the discovery of new scientific findings: models of material-transfer processes in the arc welding process; procedures and algorithms of on-line monitoring of weld quality, which are suitable for the implementation as an embedded system in the welding apparatus.
Advances of industrial research: the research results are a basis for the development of a welding-machine prototype with the high-performance embedded system.
Significance for the country
The welding technologies and manufacture of welding apparatuses represent one of major export products for Slovenia. The majority of these products, however, is of a too-low technological level, shown in a too low added value, so that they need to be upgraded in the years to come or be replaced by more modern ones. It should also be underlined that one of the best ways of increasing our identification is the presence of high-quality Slovenian products at world markets, which may a favourable influence on the national pride and self-confidence. The research results will be presented to a wider professional audience at home and abroad at various congresses and in periodic technical and scientific publications.
Based on the project research results the beneficiaries - users are planed a series of new products, i.e. welding apparatuses with a highperformance computer system as the embedded system permitting the application of new technologies, digital regulation of the welding source as a whole, an efficient user-friendly interface, upgrading of software relevant to the requirements of technologists, communication and on-line control of weld quality and technological parameters. The new products in a higher price range are expected to increase competitiveness at foreign markets. Indirectly the research results will affect also an increase of the quality of welded structures.
