The welder would need to begin with a large root gap and after that be extremely careful not to "push via" excess filler steel to create weld accumulation on the within the tube.


1, condition 6. 1, calls for welding inspectors of all degrees to pass an eye evaluation, with or without corrective lenses, to show near vision acuity, in at the very least one eye, on Jaeger J2 letters or smaller sized at a distance not less than 12 inches. A shade understanding examination and a contrast differentiation tones of grey examination have to be taken, however the company establishes the approval for these two examinations based on the weld examination being performed.
