Why didn't the welder tell me the correct technique of welding the concrete steel bar the angle iron 

Hello In this video, the welding of steel rod on angle iron in the form of 1f is demonstrated with two methods, in the first method, low-grade welding is done in a direct way, which is non-standard, and in the second method, welding with a proportional grade. It is done with the work piece and in a zigzag manner, which creates a standard, strong and beautiful weld. You will become a master in everything with practice. I hope it is useful.
