Abstract
Zavarivanje je najrašireniji postupak spajanja materijala. Kako bi se dobila zahtjevana kvaliteta zavara, certificira se oprema za zavarivanje, postupak zavarivanja, zavarivač i svi ostali parametri koji utječu na zavar. Jedan do najbitnijih cerfifikata je certifikat za postupak zavarivanja, a najutjecajnijih certifikacija zavarivača. U ovom radu su opisani postupci certificiranja postupka zavarivanja po TIG-u i certificiranje zavarivača po REL-u. Detaljno su opisana oba postupka zavarivanja, parametri zavarivanja, elektrode i dodatni materijali, njihove prednosti, nedostaci i pogreške. Kod certificiranja postupka zavarivanja po TIG-u napravljen je pWPS po kojem je zavarivao certificirani zavarivač. Nakon toga je zavar ispitan razornim i nerazornim ispitivanjima, čiji su rezultati bili ključni za dobivanje certifikata. Svih 6 ispitivanja je zadovoljilo te je postupak dobio atest. Certificiranje zavarivača po REL-u je izvedeno na način da je kandidat za certifikat zavarivača dobio WPS po kojem je zavarivao uzorak gdje se provjeravala njegova sposobnost, vještina i znanje. Uzorak je ispitan sa 2 nerazorna ispitivanjima te zavarivač nije dobio atest radi loše tehnike rada i prevelike brzine zavarivanja, zbog kojih je došlo do nedovoljne penetracije korijena zavara koja se vidi na radiogramu.
Abstract (english)
Welding is the most widely used material bonding process. In order to obtain the required weld quality, welding equipment, welding process, welding and all other parameters affecting the weld are described. One of the most important certifications is the welding process and the most influential certification of welders. This paper describes the certification of welding procedures by GTAW and certification of welder by SMAW. Both welding procedures, welding parameters, electrodes and additional materials, their advantages, disadvantages and errors are described in details. For certification of GTAW welding procedure, pWPS was made, and was welded by it, by certified welder. Subsequently, the weld was examined by destructive and non-destructive tests, the results of which were crucial for obtaining the certificate. All 6 tests was made, and the procedure passed for certificate. Certification of welders by SMAW was performed in such a way that the candidate for the welding certificate welded the sample by gotten WPS check his ability, skill and knowledge. The sample was tested for 2 non-destructive tests and welder did not get the certificate because of bad work techniques and fast welding speed, whose result is insufficient root penetration that is visible on the radiogram.
