Welder is one of the seven trades for which DGT sends one uniform practical paper to every ITI (DGT's guidelines for the All India Trade Test of July 2026). The pass mark is 60% of the practical marks, and the examiner checks your training portfolio before giving marks.
The jobs below come from the learning outcomes in the Welder CTS 2.0 curriculum (revised July 2022). The paper names the joint, plate or pipe size and position.
