Just not informative or helpful. It's part of a larger series; maybe some of the useful information is covered in other videos (I won't be checking to see). Basically, he races through a project - he shows a doodled-out hand-drawn sketch of a railing, then discards the drawing for the rest of the video. He welds up the railing in about 20 minutes. He mentions placing welds "strategically" (to avoid bending) but there's almost no mention of what the "strategy" is or how he's applying it. He mentions twice that you need to be careful in not grinding down your welds too much - he wants a specific amount of weld left over - but there's never a close-up of his welds or his grinds or any indication what he's talking about. These are the only two examples I can think of that actually referenced technique or strategy or assembly or any teaching at all - and they both sucked. Otherwise, it's watching some guy weld a basic project made exclusively of 90 degree joints from across the room and not learning anything. You did more than this your first week of shop class.

What are the teaching goals of the video? Why the cutting torch and not the chop saw for your 45o cut? Why these materials? Why this layout? How did you design the project? Where is the job where you plan to install it and how did the site impact your design? Any tips on layout or marking? What is your marking pencil (I want one - it seems to work great - but I don't know what it is)? Why does welding the inside corner last reduce bending? Would your setup be different for other material (say solid stock or round stock)? What about setup and building of something 3-dimensional (this project is basically flat) - what kind of jigs, supports, and/or clamps might be necessary? What do properly ground welds look like (I wouldn't ask, but you mentioned it twice)? How did you fabricate the bolt plates? How were they designed? How does the railing look installed?

If you're looking for tips or suggestions or even useful demonstrations/examples, this isn't the video for you. It's just a cursory run-through with almost no useful information for welders of any level.
