Ověření technologie svařování heterogenního svarového spoje

Abstract

This Dissertation Thesis is concerned with Heterogenous Welded Joint solution, which comes into being when installing a retrograde flap L10 DN150 PN40 into the pipeline route of the technological steam. This requirement became during preparation of a Project Documentation in the Planning and Designing Třinec joint-stock company. The aim of this Dissertation Thesis is to elaborate a technological and constructional resolution of installing a retrograde flap into the pipeline route and afterwards to make a preliminary specification of pWPS welding advancement, according to achieved results. In the first part of Dissertation Thesis I carried out a description of the layout solution of retrograde flap placing and a description of its function. I also specified basic materials. In the experimental part of Dissertation Thesis I examined in detail and analysed possible technological and constructional solving variants of installing a retrograde flap and according to a choosen variant I carried out an analysis of a technological welding advancement. In the final part of Dissertation Thesis from achieved results I drew up preliminary specifications of pWPS welding advancement.
