Abstract
Rad se bavi analizom unosa i provođenja topline pri TIG zavarivanju bakra i njegovih legura. Zbog visoke toplinske vodljivosti bakra, održavanje optimalne temperature zavarivanja predstavlja izazov. Cilj istraživanja bio je ispitati distribuciju temperature tijekom procesa protaljivanja, a ne zavarivanja, kako bi se minimizirao utjecaj faznih promjena u materijalu. Provedeni su eksperimentalni i numerički pristupi, uključujući ANSYS simulacije, radi boljeg razumijevanja toplinskih procesa. Eksperimenti su omogućili mjerenje distribucije temperature na simetričnim točkama ploča pomoću termoparova, dok se pokretni izvor topline kretao preko bakrenih ploča. Analizirani su parametri kao što su brzina izvora, vrsta zaštitnog plina i početna temperatura materijala. Rad također obuhvaća preporuke za optimizaciju parametara zavarivanja radi postizanja kvalitetnijih spojeva te smanjenja deformacija zavarenih materijala.
Abstract (english)
The paper focuses on the analysis of heat input and conduction during TIG welding of copper and its alloys. Due to the high thermal conductivity of copper, maintaining the optimal welding temperature presents a challenge. The goal of the research was to examine the temperature distribution during the process of gouging, rather than welding, to minimize the impact of phase changes in the material. Experimental and numerical approaches were conducted, including ANSYS simulations, to better understand the thermal processes. Experiments allowed for the measurement of temperature distribution at symmetrical points on the plates using thermocouples, while the moving heat source passed over copper plates. Parameters such as the speed of the source, type of shielding gas, and the initial temperature of the material were analyzed. The paper also includes recommendations for optimizing welding parameters to achieve better-quality joints and reduce deformation of welded materials.
