Final answer:
The CSA W47.1 standard pertains to welder certification and procedures. To perform complete joint penetration butt splices on tubular sections from one side, a welder must use a specific process approved by CSA W47.1, which could include SMAW, FCAW, GMAW, or SAW. The exact requirement however cannot be provided without referencing the standard directly.
Step-by-step explanation:
The student is inquiring about qualifications for a CSA W47.1 welder to perform complete joint penetration butt splices on tubular sections from one side. The CSA W47.1 standard relates to the certification of companies involved in welding, the qualification of welding procedures, and the certification of welders and welding supervisors.
For a welder to perform complete joint penetration butt splices on tubular sections from one side, a specific welding process must be used. The processes listed, such as Shielded Metal Arc Welding (SMAW), Flux-Cored Arc Welding (FCAW), Gas Metal Arc Welding (GMAW), and Submerged Arc Welding (SAW) are all various forms of arc welding that use different kinds of filler materials and shielding gases. However, without specifying which process is required by the CSA W47.1 for this type of welding, it is not possible to accurately answer the student's question.
