Welding Position (Posisi Pengelasan)
Flat position (Posisi Datar) Horizontal position (Posisi searah sumbu Datar) Vertical position (Posisi Tegak)Overhead position (Posisi di atas Kepala)Dalam posisi ini, Pipa tidak boleh diputar atau di roll pada waktu pengelasan terjadi.Dalam posisi ini, Pipa diputar atau di roll pada waktu pengelasan terjadi.
Non Destructive Test (NDT)
1. Magnetic Testing (MT)Magnetic Testing (MT) is a Non-Destructive Testing method used for surface or near surface breaking defect detection. MT is a fast and relatively easy to apply and part surface preparation is not as critical as it is for some other NDT methods. These characteristics make MT one of the most widely utilized NDT methods. MT uses magnetic fields and small magnetic particles,
