Welding high alloyed steels with TIG welding procedure

U radu je istraženo kako je nastao sam postupak TIG zavarivanja, način rada samog postupka, te područje primjene ovog postupka zavarivanja. Nadalje je opisan kompletan sustav koji je potreban da bi se samo zavarivanje odvijalo na onaj način na koji bi smo dobili najkvalitetniji zavar. Prije same izrade zavara potrebno je pravilno pročitati uputu za zavarivanje tako da se zavar ne bi nepravilno izveo. Prilikom izrade zavara visoko-legiranih čelika svaku smo operaciju kontrolirali tako da bi se dobila tražena kvaliteta zavara, te da bi se zadovoljili zahtjevi kupaca. Nakon zavarivanja spoja slijedi operacija toplinske obrade koja se iščitava iz upute za toplinsku obradu. Potom se zavar podvrgava propisanim ispitivanjima specifične za zavarivanu dimenziju cijevi i vrstu materijala.The paper analyzes how did the TIG welding procedure developed, the way of working itself, and area of using this type of welding. Further it has been written complete system that has been used so that welding can be done on the way that we get the best quality of the weld. Before we start welding it has been necessary that we read the welding procedure specification correctly so that the weld can be done properly. At the making of the weld of high alloyed steels we controlled each operation so that we get weld of requested quality, and also to achieve buyer demands. After welding what goes next is heat treatment operation which we can read from instruction for heat treatment. What comes next is requested testing specific for welded dimension of the tube and type of material
