Efforts to reduce the level of distortion by welding treatment need to be done, but must consider the quality of the weld, especially the weld joint area. This study aims to examine non-destructive test (NDT) on welded objects with clamp and heat sink treatment to determine the level of weld perfection and detect welding defects in order to ensure weld quality. This research was conducted with 4 welding treatment designs, include: as welded, 4-point clamp treatment (4Clamp), liquid nitrogen cooling (HS-N2) heat sink treatment, and flowing watercooling (HS-H2O) heat sink treatment. The results showed that based on the visual test of the welding on as welded condition, 4-points clamp, and flowing water cooling heat sink treatment decided "accepted", while the heat sink treatment with liquid nitrogen did not pass the test and decided "rejected". The dye penetrant test results of the HS-N2 treatment detected cracks at the end of the weld surface caused by a decreasing of heat input due to the HS-N2treatment. © 2020 Institute of Physics Publishing.
