Is is permisiable per AWSD1.6 to make a single sided CJP weld without a backing bar? Fabricator tells me that using an initial GTAW pass eliminates the need for backing and also for backgouging. Plate is typically 3/8" thick. Are there any additional testing or WPS requirements for this type of procedure?
