Abstract

U završnom radu obrađena je tema aditivne proizvodnje električnim lukom i žicom pomoću CMT postupka. Rad se sastoji od teorijskog i eksperimentalnog dijela.
U teorijskom dijelu rada objašnjene su osnove aditivne proizvodnje, njene prednosti i nedostaci te parametri teksture površine dobivenog izratka. Teorijski je obrađen CMT postupak zavarivanja, njegov princip rada, prednosti i nedostaci te par primjera primjene.
U eksperimentalnom radu napravljena su tri uzorka WAAM postupkom pomoću robotske stanice CMT postupkom, svaki sa svojim setom parametara te su ispitana njihova svojstva. Pomoću 3D skeniranja određeni su parametri teksture površine, određen je BTF omjer i izmjerena tvrdoća uzorka.

Abstract (english)

In this thesis, the topic of Wire and Arch Additive Manufacturing-WAAM using CMT process is discussed. The paper consists of a theoretical and experimental part.
In the theoretical part, the principles of additive manufacturing were explained, along with its advantages and disadvantages and the parameters of surface texture of the product samples. The CMT welding process, the principle of operation, advantages and disadvantages and the examples of the application of this welding procedure for Wire and Arch Additive Manufacturing are described.
In the experimental part, three samples were made using the robot station and CMT process, every sample with their own set of parameters. 3D scanning of created walls (samples) has been performed and surface texture parameters were determined so as BTF ratio and the hardness was measured.
