Abstract
Zaradi potrebe po visokokakovostnih zvarih v sodobnih izdelkih je varjenje TIG vse bolj pogosto. A-TIG varjenje je posebna izvedba varjenja TIG, pri katerem uporabljamo aktivne delce, ki skoncentrirajo obločno energijo, povečajo globino prevaritve in posledično skrajšajo čas varjenja. Izvedli smo avtomatsko A-TIG varjenje avstenitnega nerjavnega jekla AISI 316L v sočelnem spoju ter izvedli preizkuse zvara za izdelavo atesta varilnega postopka. Ta je zajemal pripravo in analizo makroobrusa, ter natezne in upogibno testiranje zvarnega spoja. Trdnost zvara in osnovnega materiala sta bili primerljivi. Posledično je pri nateznem preizkusu prišlo do loma v zvaru in ne v osnovnem materialu. Zvar je uspešno prestal tudi upogibni preizkus. Makroskopska analiza je pokazala, da je izdelan zvarni spoj brez napak.

Secondary title: |
A-TIG welding of austenitic stainless steel AISI 316L |
Secondary abstract: |
Tig welding is getting more and more common in modern production due to the demand for high quality welds in modern products. A-TIG is one variant of TIG welding that utilizes active particles which concentrate arc energy, increase penetration depth and consequently reduce welding time. We conducted automatic A-TIG welding of austenite stainless steel AISI 316L using a butt joint and ran adequate tests required for welding procedure certificate. The test contained preparation and analysis of the macro specimen, tensile test and bending test. The weld's tensile strength was comparable with the tensile strength of the original material. Consequently, while conducting a tensile test, the specimen cracked in the weld, not the material. The weld also passed the bending test. Macroscopic analysis has shown the finished weld to be without error. |
