If one looks at the sequence in which welding skill is imparted, it is based on the order in which technology has evolved.
This is akin to forcing someone wanting to use computers to learn MS DOS and Windows 3.1 because those technologies came first, much before Windows 7 or 8.
MIG and TIG are the most commonly used types of welding, especially in the automotive industry. The remuneration is also considerably higher than Gas Welding and Arc Welding, and so is the quality expected from the welder.
Since the formal vocational training syllabus enforces this order, someone who needs to know just MIG or TIG is forced to learn Gas and Arc welding.
If one now looks at different types of welding from a purely human skill approach, the following approach is more optimal:
The Modular Employability Skills is a good initiative enabling youth to acquire skills one by one, throwing the doors open to youth who had missed out on more formal training courses like ITIs and Polytechnics. However, for skills relevant to welding (Sl # 98 to 108). though MIG welding alone is available as a course of 90 hours, it requires you to have Stick Welding and Gas Cutting courses, each of 120 hours, as a prerequisite!
It is high time the industry lobbied for changing the sequence of skill training in the manner required by the industry, and not an obsolete one just because “that’s how it was from time immemorial”.
