Pipeline Welding and Inspection to API 1104

On a cross country pipeline the girth weld is made in the open, often downhill, by a spread of welders advancing several kilometres each week, and every joint must pass before the ditch is closed. API 1104 governs that work. Delegates start with procedure qualification for cellulosic stick, low hydrogen and mechanised welding, and the changes that force requalification, then move to welder qualification by single and multiple qualification tests. Nick break, root bend and face bend specimens are interpreted on real samples. The production acceptance standards for radiography and automated ultrasonic testing are covered defect by defect, followed by welding on pressurised lines, hot tap fittings, burn through and hydrogen cracking. The final session introduces alternative acceptance criteria based on engineering critical assessment, and the girth weld records a spread should keep.

5 day course
