The Combination of welding and soldering for repair of frames of transport vehicles.

Abstract

The frame constructions of transport and technological machines perceive the static load and dynamic load as a result of hat in the process of exploitation cracks and other damages on certain areas are appeared. By the problem of establishment of elements of strengthening in dangerous areas, and also proceeding in descriptions of durability of such areas with the engendered cracks, there is a danger of damage of parent metal frames due to negative processes, which can take place during welding. For indemnification of these negative consequences a scarf-welding method is developed, which provides for placing in the area of temperatures, which provide its melting, soldering material on the basis of copper between details which weld. It is well-proven researches, that renewal and strengthening of steel constructions by the use of the developed technology of welding and soldering with the use of solders on the basis of copper except for the increase of descriptions of durability provides effective slushing defence of surfaces of details in the thermal affected zone.
