Inspection of Smaw Position 3G Material ST 37 Welding Results using the Penetrant Test (Pt) And Magnetic Test (Mt) Of Students At Subang State Polytechnic

Abstract

This study intended to get a clear picture of the readiness of students to take welding certification for the competency test scheme “Welding SMAW 3G”. Five students in semester 4 of the POLSUB machine maintenance study program randomly selected to do the ST 37 material welding with the 3G position for butt weld and inspected using the Non-Destructive Test (NDT) Penetrant Test (PT) and Magnetic Test (PT) methods to get a prediction of student passing rates in the certification process. The results show that Specimens 1, 3, and 4 for PT testing are rejected and the MT test results are rejected where the length of the undercut defect is> 100 mm and the standard is only <50 mm. Specimens 2 and 5 are declared to have passed the PT and MT test because the defects in the specimens are still included in the standard where the undercut or indication of defects that occurs is still below <50 mm.
