Povzetek
Varjenje je spajanje dveh ali več delov v eno, nerazdružljivo celoto, ki jo imenujemo zvarjenec. Z varjenjem je mogoče spojiti kovine, polimere, stekla, keramike, karbide, kompozite itd.. Lahko pa se med seboj varijo tudi kovine in nekovine. Pri varjenju kovinskih materialov poznamo v osnovi dva tipa varjenja. Prvi tip varjenja je varjenje pod pritiskom, drugi način pa je varjenje s taljenjem.
Ker svetovni trg vedno bolj teži k avtomatizaciji proizvodnih procesov, so se roboti do danes uveljavili v marsikaterem tehnološkem in proizvodnem procesu, saj so se izkazali za zelo učinkovite. Glavni razlog za avtomatizacijo so kakovost, nižji stroški in razbremenitev delavcev. Kljub temu, da se robotsko varjenje še vedno razvija, pa je vedno bolj uveljavljeno v več podjetjih. Robotsko varjenje izvajajo izključno v naprej programirani roboti, ki se odlikujejo predvsem po svoji zanesljivosti. Če se na primer postavimo v vlogo varilca, je znano, da smo s tem izpostavljeni različnim poškodbam in tudi boleznim dihal, zato je verjetnost bolniškega dopusta toliko večja. Z uvajanjem robotov v proces varjenja tako bistveno prispevamo k večji zanesljivosti in tudi kakovosti delovanja, saj so sposobni nemoteno delovati tudi po 24 ur in več. Podjetja s tem dosegajo večjo kakovost, produktivnost in tudi manjše stroške proizvodnje. Zato se
robotsko varjenje splača predvsem ob večjih naročilih, saj je ponovljivost varjenja brez napak izjemno visoka, res pa je, da je potrebno robote v tem primeru ustrezno sprogramirati.
V nalogi bodo obravnavani enovarkovni navari na ravnih ploščah, ki se v praksi veliko uporabljajo za popravilo poškodovanih površin energetskih komponent in zvišanje mehanskih lastnosti osnovnega materiala.
Izvedena bo kontrola kvalitete navarkov (var + toplotno vplivano področje) s pomočjo razreza navarov in izvedbo metalografske preiskave prereza navarka.

Welding of steel surfaces using robotic welding |
Sekundarni povzetek: |
Welding is the joining of two or more parts into one, inseparable whole, which is called a weldment. Metals, polymers, glasses, ceramics, carbides, composites, etc. can be joined by welding. Metals and non-metals can also be welded together. When welding metal materials, there are basically two types of welding. The first type of welding is pressure welding and the second method is fusion welding.
Since the world market is increasingly moving towards the automation of production processes, robots have established themselves in many technological and production processes to date, as they have proven to be very efficient. The main reason for automation is quality, lower costs and relief from workers. Despite the fact that robotic welding is still developing, it is increasingly established in more companies. Robotic welding is performed exclusively in the forward direction programmed robots that stand out above all for their reliability. If, for example, we put ourselves in the role of a welder,
we are known to be exposed to various injuries and respiratory diseases, which is why the probability of sick leave is that much greater. By introducing robots into the welding process, we significantly contribute to greater reliability and also the quality of operation, as they are capable of working uninterrupted even for 24 hours or more. Companies thereby achieve higher quality, productivity and lower production costs. Therefore, robotic welding is especially worthwhile for larger orders, as the reproducibility of welding without errors is extremely high, but it is true that the robots must be properly programmed in this case.
The task will deal with single-wave welds on flat plates, which are widely used in practice to repair damaged surfaces of energy components and increase the mechanical properties of the base material.
Quality control of welds (var + heat-affected area) will be carried out with the help of sectioning of the welds and metallographic examination of the cross-section of the weld |
