INSTALLATION FOR STUDYING THE THERMOPLASTIC STRESS RELIEVING

摘要

The invention relates to an installation for studying the thermoplastic stress relieving, meant for establishing the optimum conditions for reducing stress in the welded metal assemblies. According to the invention, the installation consists of an electrically driven movable carriage (1) having mounted thereon a cooling device (14) in the shape of horizontal parallel pipes (16) connected to a manifold (17). The cooling device (14) is mounted on the movable carriage (1) by means of a support (15) provided with a positioning groove (a). On a support (23) there leans a weld seam (c) of a specimen (20), said seam being oriented to the moving direction of the movable carriage (1).
