We are retracting this article because it is a duplicate translation of an article that originally appeared in the Quarterly Journal of the Japan Welding Society. The retraction is not due to any fault of the authors.
We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
