Questions
Which syllabus does this course follow?
The NCVT / DGT CTS (NSQF) Welder Trade Theory syllabus. The centre follows the student's own ITI syllabus where it differs.
Is this course only theory?
Yes, this is the trade theory paper; the matching Welder Trade Practical course covers hands-on welding.
Are TIG and MIG covered?
Yes, MIG/MAG, TIG and plasma cutting are part of the current syllabus.
Does it help in getting a welder job?
Yes, it builds the theory needed for AITT, apprenticeship and welder qualification tests.
