Contact flash welding (CFW) is a high-performance technological process in which the welded parts are pressed together by coupling edges.

Considering high requirements for the quality of welded joints, YUZHMASH uses the best welding materials of Russian and foreign manufacturers.

The company provides a contact flash welding of extruded sections, tube preforms of steel and aluminum materials.

The company renders service of contact flash welding of extruded sections, tube preforms of steel and aluminum materials.

YUZHMASH applies welding technology in semi-solid phase. This radically simplifies the process of welding of aluminum alloys type AMG-6, 01570.

CFW ensures high quality and reliability of welded joints. The process of welding is carried out in a short period of time, which saves electricity. The process runs in automatic mode, which ensures high stability of the welding process in accordance with the specified mode.

The advantages of CFW:

  • high performance;
  • high quality of welded joints;
  • reliable connections;
  • high technical and economic indicators of

The unique welding equipment securely pressed together extruded sections with a diameter over 800 mm and a height of 400 mm

The technology is widely used in the production of heavily loaded units of launch vehicles.

Applications

Heavily loaded units of launch vehicles:

  • frame made of high-strength steels and aluminum alloys;
  • shells of body made of AMG6 alloy, diameter of 1800 mm or more, cross-section up to 100,000 mm2 (50 x 200 mm);
  • fitting + stringer of high-strength steels.

The original solution implemented in the construction of launch vehicles units, which have fitting + stringer, formerly connected with riveting.

Replacement of riveted joints welded reduced the weight of the structure and provide high performance products.
