Which combination of factors contributes to a reduction in labor and time with fusion welding?

The combination of factors identified in the correct answer – automation, reduced labor, and reduced time – effectively illustrates how fusion welding can become more efficient. Automation involves the use of advanced machinery and technology to carry out welding tasks, which can significantly streamline the welding process. This eliminates many manual tasks that traditionally require a lot of human labor, thereby reducing the overall amount of labor needed.

Furthermore, with automation, processes can be performed at a faster rate, thus reducing the time required to complete welding tasks. This combination means that the operations can be done more efficiently compared to traditional methods that rely heavily on manual intervention. Ultimately, this leads to a faster production cycle, lower labor costs, and often improved precision and quality in welding output.
