Welding of aluminium sizable weldments.

By Jan Tkaný

Abstract

This thesis created within the general Bachelor's study gives insight into the basic division of aluminum alloy, a summary of technologies and principles of welding aluminum and its alloys. It is focused on the description of cutting Al alloy and their suitability for welding, the characteristics of different methods and description of problems in the welding of large-scale aluminum weldments. For each of the methods are given the possibility of application, a description and diagram of operation and specifics on the protective gas or electrodes. Problems in the welding of large parts are characterized by external and internal deformations, complex stress fields, where appropriate, the temperature fields. To determine the size of the deflection angle is given an example of the chart for the practical use. In conclusion it is stated that the method is appropriate to apply in case of large weldments
