Welding calculations were made by such methods as: mechanized argon-arc welding with a consumable electrode, plasma and manual argon-arc welding with a non-consumable electrode. Objectives of the final qualifying work: â analysis of scientific and technical information on the weldability of aluminum alloys used in the production of the collector; â select and justify welding methods; â select the main and auxiliary welding equipment, welding materials; â develop a welding technology; â to analyze the normative and technical literature on reservoir quality control. For the manufacture of the collector, in this case, the AMg3 alloy was chosen as the base metal. This alloy has increased strength and fluidity, low cold brittleness threshold. Has a higher corrosion resistance compared to carbon steels, well welded without restrictions in a wide range of welding. Also, at low temperatures, steel has better impact toughness and high mechanical characteristics, which makes it possible to reduce the metal consumption of the structure. The optimal geometrical dimensions of the collector were selected, a check was made according to the condition of strength and stability - the collector meets all the requirements. All loads acting on the collector are taken into account. Mechanized TIG welding was chosen as the main welding method. The selected equipment and consumables meet the requirements of the process. |
