Abstract
The results of experimental work on the restoration of art castings from copper alloys are presented. It is shown that an individual approach is required during product repair, which is associated with the different chemical composition and presence of defects in the cast metal, the shape and size of the product, the need to adjust the chemical composition of welding consumables, etc. It is determined that when restoring bells, the most appropriate process for performing repair work is the process of manual argon-arc welding with a nonconsumable electrode (TIG process). It is shown that positive results in welding up cracks in church bells while ensuring their high acoustic properties are achieved with the correct choice of filler material. Coated- electrode welding can be recommended for welding up casting defects, as well as for manufacturing welded components of sculptures. alloys with variable thicknesses ranging from 45 to 65 mm while maintaining the same number of passes.
