EVALUATING THE QUALITY CONTROL OF JOINTS MADE BY ROBOTISED TIG PROCES

ISPITIVANJE KONTROLE KVALITETE SPOJEVA IZRAĐENIH ROBOTIZIRANIM TIG POSTUPKOM Zavarivanje je spajanje dvaju ili više, istovrsnih ili raznovrsnih materijala, taljenjem ili pritiskom, sa ili bez dodavanja dodatnog materijala, na način da se dobije homogeni zavareni spoj . Kako je zavarivanje općenito težak i monoton posao, ponekad i opasan po život zavarivača, javila se potreba za uvođenjem automatiziranog sustava, odnosno robota u sam proces (industrijski robot). Rad je koncipiran u nekoliko cjelina. U uvodu je ukratko opisana uloga i povijest zavarivanja. Druga cjelina predstavlja sve o TIG postupku zavarivanja i potrebnoj opremi. Modificirane varijante TIG zavarivanja opisane su u trećoj cjelini. U četvrtom poglavlju definirana je zona spoja i granice debljine. Peti dio rada opisuje s robotske stanice, načini programiranja i primjena senzora za korekciju putanje zavarivanja. U nastavku je analiziran praktični dio rada. Na kraju rada nalazi se osvrt na diplomski rad u cijelosti.EVALUATING THE QUALITY CONTROL OF JOINTS MADE BY ROBOTISED TIG PROCESS Welding is a process in which two or more identical or varied materials are joined by melting or by pressing, with or without adding an additional material, to obtain a homogeneous welded joint. Since welding is generally difficult and monotonous, sometimes dangerous to the life of the person performing the weld, there is a need to introduce an automated system, i.e. robots into the process itself (industrial robot). The graduation thesis is composed of eight chapters. The introductory part briefly describes the role and history of welding. The second chapter is about TIG welding and the necessary equipment. Modified variants of TIG welding are described in a third chapter. In the fourth chapter, the joint zone and the thickness limit are defined. The fifth chapter of thesis describes robotic cells, programming modes and application of welding path correction sensors. Further is an analysis of the practical part of the thesis. At the end of the thesis there is a conclusion
