The CWB certifies the welders. The company (or subcontractor, in our case) must also be certified by CWB and have a copy of their procedures available to inspector of engineer. Personally, I usually ask for welding tickets and procedures during jobsite orientation.
Yes, there are people that try and say they are something they are not, A guy claiming to be a welder won't last very long if he can't do his job. But its like anything, owners want fast and good, sometimes both don't coincide. I've seen guys that are licsened electricians that can't run conduit to save their lives, but yet, have seen some 2nd yr apprentices do 500' ft a day c/w bends and boxes.
To answer your question,as far as I know,the OCT has nothing to do with training and certifiying trades.
My most recent experience with them.....young lady showed up at my trailer wanting to see everyone's "cards".... 40 guys on site....I said no,will not shut down my jobsite for you or any one else.I informed her that there are only a few of the compulsory trades and that I would take her to see those guys only.They all had their cards except for one hvac guy.Turns out that her visit was soley aimed at the one guy ......,pretty sad way of doing business if you ask me....,cause havoc with a whole bunch of ppl .....misrepresent yourself just to weed out one fricken guy ....,I am not impressed
