Applikationer för effektiv inlinekontroll inom svetsande industri : Möjligheter och utmaningar vid implementering av nya kontrollmetoder / Applications for efficient inline control in the welding industry : Opportunities and challenges in implementing new control methods

Lindén, Jonathan, Öbrink, Erik January 2021 (has links)
Svetsning är en viktig fogningsmetod, och kvalitet på svetsar kan ha hög inverkan på prestanda och livslängd för svetsade produkter. För att kunna garantera att svetsar lever upp till de krav som ställs används ofta oförstörande provning. Traditionella oförstörande provningsmetoder kan dock vara oprecisa, långsamma och kräva högutbildade operatörer. För att förbättra kontrollen av svetsar utvecklas därför ny mätteknik som snabbare och mer pålitligt kan bedöma svetsars kvalitet. Genom att intervjua företag inom svetsande industri har slutsatsen kunnat dras att det finns behov av tillförlitliga mätmetoder som kan hantera komplexa geometrier, leverera lättolkade data och som är enkla att implementera. Forskningen om kontrollmetoder för svetsar, och tolkning av datan metoderna producerar, är dock i olika tidiga stadium för olika svetsmetoder. Generellt behövs fler tester av utrustning i utmanande förhållanden samt mer forskning som riktar sig åt att lösa de problem som industrin upplever. / Welding is an important joining method, and the quality of welds can have a severe impact on the performance and life span of welded products. In order to guarantee that welds meet their requirements, non-destructive testing is widely used. Traditional non-destructive testing methods can, however, be imprecise, slow and require highly educated operators. New measuring techniques are therefore being developed to inspect faster and more reliably the quality ofwelds. Through interviews with companies in the welding industry, the conclusion can be drawn that there is a need for reliable inspection methods that can handle complex geometry, provide easily interpreted data and that are simple to implement. The research about inspection methods and the data they provide are, however, in different stages of their development, depending on the welding method. There is generally a need for testing of novel measuring equipment in more demanding settings, as well as more research aimed to solve the problems the industry experiences.
