Bronze products after casting often have voids and shells, which makes them of little use for later use. Argon welding technology is used to weld such defects. Quality welding is carried out after preheating of the items to a temperature of 325 ° ... 400 ° C, and with increasing size of parts the heating temperature should be increased. When welding in argon the defective areas are welded on the surface, and the final shape of the connection zone is set with a welding electrode. For rolled bronze, as well as forged parts, argon welding is carried out to improve the strength and hardness of the surface. In order to obtain a fine grain structure the item to be welded is first pressed in the press at room temperature.

DC welding

The welding of bronze in argon is carried out with reverse polarity direct current. At the beginning of welding current density is set to a minimum permissible values (15 ... 20 A / ^mm2), and then bring up to 45 ... 50 A / ^mm2. Buy welded bronze products company offers Evek GmbH.

Alternating current

The use of alternating current welding is possible in principle, but it is not rational, because the current has to be increased to 75 ... 80 A because of the high duty cycle of the process. Only in this case it is possible to maintain the same welding productivity parameters for bronze parts. Welding is carried out in one layer, moving the electrode along the surface with a 15 ... 20° inclination to the surface perpendicularity and making zigzagging movements.

Electrodes

To obtain a homogeneous weld, the electrode material must be of the same grade of bronze as the parts to be joined. In some cases, you can use non-consumable tungsten electrodes.
