A strong weld means a strong pipeline

摘要

Aymeric Fournel, Protem GmbH, France, details some of the most common defects found in welded joints, and how to avoid them in the construction of pipelines. Defects of a welded joint are very often due to a poor pipe end preparation. Indeed, despite using welding stations on the cutting edge of technology, the stage prior to welding, i.e. preparing the pipe ends to be welded together, is often neglected or done with unsuitable techniques.
