I am welding 3/4 inch plate to an I-beam that has a flange about 5/16". Print asks for a 1/4" weld and I am running .052 metal cored with settings about 26.5volts and a wire feed of about 310.
Now, I have heard what you are saying, among other things. Some people have said that this line means good fusion, but I was inclined to believe that. I have also heard that the line is from the wire dragging, but in spray arc, the wire really never drags in the puddle, correct? It sort of "chops off" between the electrode and work piece.
Also, to the rest of my question, does this line create the chance of a longitudinal crack? I was told that it could be a weak point.
