In this paper, the authors discuss the method of deformations compensation (resulting from the impact of variable temperatures and pressure) in pipelines intended for fluids transport (liquids and gases). Classical methods of compensation through the so-called "natural compensation" and using special devices called expansion joints. In this paper authors present research work on a new type of the metal expansion joints, called bellow-lens expansion joints. The mechanically assisted laser forming method, which was used to manufacture the bellow-lens expansion joints, was presented. The method uses CO 2 laser radiation to heat the element from which the expansion joint will be made and the proprietary system consists of an actuator and swivel handle.

Abstract. This paper discusses the technological assumptions for the production of helical metal expansion joint as a new type of expansion joints used to eliminate torsional deformations of industrial pipelines. The method of mechanically assisted laser forming, which was used as a manufacturing technology, was presented as well. Furthermore, technological parameters and experimental results obtained during the fabrication of helical metal expansion joints were presented. Mainly presented and discussed are the results such as: obtained geometry, forces necessary to produce the product, processing temperature, strain rate and others. Satisfactory treatment results were obtained, which are illustrated below.

In the paper, the author presented the technological assumptions for the production of a helical metal expansion joint. Currently produced expansion joints have bellows or lens shapes. These types of expansion joint can only carry lateral, angular and axial deformations. A helical metal expansion joint is a new type of expansion joints that can compensate for torsional deformations of industrial pipelines, which are the result of the installed armature in the piping system. The authors presented a method of mechanically assisted laser forming, which was used as a manufacturing technology for this type of element. This technology combines laser heating of an element in the form of a pipe (implemented with a carbon dioxide laser along a given trajectory in order to plasticize the heating zone), with the simultaneous application of an external force, which is intended to plastic deform the element on its circumference. The carried out experiment consisted of the selection and control of the process temperature using an integrated optical pyrometer, based on which the laser power was controlled. According to the preliminary experiments, the compression speed of the element was selected. Compression was carried out using a mechanical actuator. During the process, the compression force that caused the deformation of the element was recorded. Experimental results obtained during the manufacturing of helical metal expansion joints are presented. Mainly, the results are presented and discussed, such as: obtained geometry, forces needed to manufacture the element, processing temperature, strain rate and others.
