Abstract
So far world-wide no uniform definition of the energy efficiency of the welding arc in welding either with a consumable electrode or a non-consumable electrode has been established yet. It was found in our previous studies that the energy efficiency in TIG welding amounted to only around 15 % and that in the other welding processes to around 20 % whereas the rest of energy got lost into the environment. These findings were published on the international level as well. Within the proposed project, it is aimed to measure and calculate the actual efficiencies in the majority of the arc welding processes and study the parameters affecting the efficiency of the energy consumed in a welding process. First a literature survey will be made. Then the equipment, parent metals, welding filler materials, various shielding gases, measuring equipment, computer hardware and software required for experimental work will be acquired. Finally extensive experimental work will be performed. Welding will be carried out using consumable and non-consumable electrodes, different shielding gases, different filler materials, new welding procedures such as multiple-wire welding, plasma-MIG welding, MAG welding with a band electrode. The experimental data will be processed. Based on the experimental results processed, mathematical and statistical models for optimization of the welding processes and production will be elaborated.. In the project, primarily home-made parent metals, filler materials, shielding gases, welding equipment and measuring equipment will be used. The majority of work will be performed for the client co-financing the project and wishing to improve productivity and efficiency of the energy consumed, increase product quality, and improve working conditions for his welders. With the present technology ,the not utilized energy pollutes workplaces and the environment. Our client produces pressure vessels of different size and exports the majority of its products to the Western European markets.
