Question

The classification required for CSA W47.1 welder to be qualified to perform complete joint penetration butt splices on tubular sections from one side is:

a. Vertical weld classification
b. Horizontal weld classification
c. Overhead weld classification
d. Fillet weld classification

Answer 1

The correct classification for a CSA W47.1 welder to perform complete joint penetration butt splices on tubular sections from one side is a horizontal weld classification.

Step-by-step explanation:

The classification required for a CSA W47.1 welder to be qualified to perform complete joint penetration butt splices on tubular sections from one side is a horizontal weld classification. This classification is necessary because the welder would be working around the circumference of a tubular section, which is considered a horizontal weld position according to the standards set forth by the Canadian Standards Association for welding. Complete joint penetration welds from one side on tubular sections are complex and require a welder with the appropriate level of skill and certification to ensure the strength and integrity of the joint.
