Abstract
Fatigue characteristics of welded joints of alloy 01420C made by resistance spot welding and automatic argon arc welding are obtained. The highest durability was shown by welded joints with a longitudinal weld. Joints Produced by resistance welding and simulating the edge line of a reinforced element have a durability comparable to an unloaded weld spot, which in turn is inferior to the durability of a joint with a longitudinal weld. The durability of elements of limited cross-section with repair welding of a mechanical cut is similar to the durability of a standard sample in the form of a strip with a hole.
Highlights
The development of state-of-the-art airframe structures is determined by solving the problems of increasing the load ratio and increasing its service life
Durability tests of welded samples made of 01420S alloy sheet were carried out on a zero cycle with a loading frequency f = 1-5 Hz
For welded joints of 01420C alloy sheets, the value of the fatigue durability of joints with a longitudinal weld exceeds its values of the samples with a transverse seam at the same level of cycle stresses
Summary
The development of state-of-the-art airframe structures is determined by solving the problems of increasing the load ratio and increasing its service life. To solve these problems, it is necessary to develop new materials and technologies for manufacturing parts and welded assemblies in general. One of the ways to solve the problem of increasing the load ratio of the airframe is applying aluminum alloys with reduced density in its structure and welding as a method of joining parts. The purpose of this work was to study the fatigue resistance characteristics of 01420 S alloy on the main structural and technological types of welded joints of sheet semi-finished products.
