Bronze ware after casting often has voids and shells, which makes them unsuitable for later use. To weld these defects, the technology of argon welding is used. Qualitative welding is carried out after preheating the products to temperatures of 325 °… 400 ° C, and with an increase in the dimensions of the parts, the heating temperature should be increased. When welding in argon, surface welding of defective zones occurs, and the final shape of the bonding zone is established with the help of a welding electrode. For bronze rolling, as well as forging into argon welding, is conducted with the aim of increasing the strength and hardness of the surface. To obtain a fine-grained structure, the product to be welded is pre-compressed on presses at room temperatures.
Welding of bronze in argon is carried out on the reverse polarity of the direct current. At the beginning of welding, the current density is set to the minimum permissible values (15… 20 A / mm 2), and then adjusted to 45… 50 A / mm 2. Evek GmbH offers welded bronze products. Price from the manufacturer. The supplier provides prompt delivery of products to any address.
The use of AC welding is possible in principle, but it is irrational, because the current must be increased to 75… 80A due to the high duty cycle of the process. Only in this case it is possible to maintain the same parameters of the welding performance of bronze parts. Welding is carried out in one layer, moving the electrode over the surface with a slope of 15… 20 ° to the perpendicular of the surface, and making zigzag movements.
To obtain a uniform weld, the electrode material must be of the same bronze grade as the parts to be joined. In some cases, non-consumable tungsten electrodes can be used.
