Today's crop is unusually thin — most candidates are hashtag-stuffed Shorts showing 90-degree joints with no real teaching. This Bengali-language explainer from Faridul babu is the standout because it actually attempts a comparative overview of the three workhorse arc-welding processes: MIG (GMAW), TIG (GTAW), and SMAW (stick).

Comparison videos like this are genuinely useful for beginners trying to figure out which process to learn first or which machine to buy. Each method has different strengths: MIG is fast and forgiving on clean steel, TIG gives the cleanest welds on thin material and exotic metals like stainless and aluminum but demands two-handed coordination, and SMAW (stick) handles dirty material outdoors and on thick structural steel where shielding gas would blow away.

A good walkthrough should cover the physics of each (consumable vs. non-consumable electrode, shielding gas vs. flux coating), the typical use cases, and the equipment cost and skill curve. If this video delivers on even half of that in a single sitting, it saves a beginner hours of fragmented research.

Note: the audio is in Bengali, so non-speakers will need auto-translated captions, but the visual demonstrations of each process should carry the core lessons across language barriers.
