Comparative Analysis of Casting and Welding for the Production of Welded Structures and Optimisation of the Welding Process to Achieve Greater Competitiveness of Welded Products

The diploma thesis focuses on a comparative analysis of two key processes in the metal processing industry, casting and welding, for the purpose of producing welded structures. The main objective of the research is to improve the competitiveness of welded products with an emphasis on optimising the welding process. The first part of the thesis provides a detailed comparative analysis of casting and welding, covering the physical, chemical and mechanical properties of the final products, as well as the economic aspects of both processes. A practical example demonstrates the method of achieving the desired results and also how the product can be optimised. This example also shows how the same product can be manufactured using different technological processes and have comparable mechanical properties.

Problem

The diploma thesis focuses on a comparative analysis of two key processes in the metal processing industry, casting and welding, for the purpose of producing welded structures. The main objective of the research is to improve the competitiveness of welded products with an emphasis on optimising the welding process.

Solution and Method

The first part of the thesis provides a detailed comparative analysis of casting and welding, covering the physical, chemical and mechanical properties of the final products, as well as the economic aspects of both processes. All these analyses contribute to easier selection of technologies for different product requirements. In the second part, we focus on optimising the welding process to achieve greater competitiveness of welded products.

The research includes a study of different welding techniques, the use of advanced materials and the introduction of modern technologies and innovations in the welding process. Particular emphasis is placed on improving the strength, corrosion resistance and aesthetic appearance of the final welded structures.

Results

A practical example demonstrates the method of achieving the desired results and also how the product can be optimised. This example also shows how the same product can be manufactured using different technological processes and have comparable mechanical properties. In this way, we wish to present customers with different options that are similar in terms of price and usability, and customers can choose different technologies in different circumstances.

The diploma thesis also touches upon digital technologies for process improvement, from various software solutions to the use of modern digital technologies. This field is developing most rapidly at present and can contribute most to the development of product technology. All companies in their development reach the inevitable step of process optimisation through digitalisation.

The diploma thesis also describes several methods that would help companies in development to select appropriate methods for process improvement and ensure competitiveness in the market. The research results will be useful for industry professionals, engineers and decision-makers in selecting the optimal production process for specific applications. In addition, optimisation of the welding process will contribute to increasing the competitiveness of products in the market, which is crucial for the success of companies in today's global environment.
