Welding
Aluminum is welded by gas and arc welding, as well as pressure on electrocontact welding machines. The most popular gas welding is an acetylene-oxygen mixture. Preliminarily the metal edges are thoroughly cleaned: by sandblasting machines, steel brushes, by shaving or by washing in gasoline or in an aqueous solution of caustic soda. After caustic soda, the parts are thoroughly rinsed with running water to prevent corrosion. When repairing aluminum castings, it is recommended that they be preheated to 300 ° C.

Butt welding
It is usually produced by the method of continuous reflow of aluminum on electric drive machines. At a current value of 15,000 A per cm2 of the welded section, the reflow value is 5−12 mm, and the draft is 1.5−5 mm, depending on the weld section. The continuous reflow time is from 30 to 70 AC periods, and the settling time is from 2 to 5 current periods. The current is switched off at the beginning of the precipitation.
Spot Welding
It is significantly hindered by the high electrical conductivity of aluminum alloys and fast melting during welding (0.002−0.005 seconds), therefore, in order to maintain the pressure and contact with the metal, a rapid displacement of the electrode of the machine is necessary. Conventional spot welding of aluminum is usually used. Electrodes for such welding are taken from copper alloys with high hardness and electrical conductivity. Have
