Answer:
CSA W59.2 standard for Welded Aluminum Construction allows the use of Flux Cored Arc Welding for joining aluminum structures. Other listed processes are less common or impractical for aluminum welding. This means the correct response is D).
Step-by-step explanation:
The CSA W59.2 Standard for Welded Aluminum Construction specifies the requirements for the design, fabrication, and inspection of welded aluminum structures. When it comes to welding processes, the standard considers several methods suitable for aluminum welding. However, among the options provided, the process specifically allowed by CSA W59.2 is Flux Cored Arc Welding (FCAW), which is often used for aluminum due to its efficiency and effectiveness in joining aluminum pieces.
Other processes like Submerged Arc Welding, Stud Welding, and Electrogas Welding are not typically used for aluminum structures as they are either impractical or less effective for this metal. Welding in general incorporates various techniques and equipment depending on the materials to be joined and the desired outcome. Aluminum, in particular, requires careful consideration of the welding process due to its unique properties, such as its thermal conductivity and oxide layer.This means the correct response is D).
