Thank you very much Sir for this educational video. I'd like to ask if Lack of inter-run fusion is the same as cold lap, and how do we differentiate between LOP and LOF on the weld plate itself?

[@WeldingandNDT]

I have uploaded seperate videos on LOP and LOF. Please watch those videos to understand the concept. Thank you. Please join my channel to watch all videos. Joining link: ruclips.net/channel/UCH7nXSievFlbRKzKzEySbkwjoin
