Summarize the limitations of flux cored arc welding.
What will be an ideal response?
The main limitation of flux cored arc welding is that it is confined to ferrous metals and nickel-based alloys. Generally, all low and medium carbon steels and some low alloy steels, cast irons, and a limited number of stainless steels are presently weldable using FCAW.
The equipment and electrodes used for the FCAW process are more expensive. However, the cost is quickly recoverable through higher productivity. The removal of postweld slag requires another production step. The flux must be removed before the weldment is finished (painted) to prevent crevice corrosion.
With the increased welding output comes an increase in smoke and fume generation. The existing ventilation system in a shop might need to be increased to handle the added volume.

Since transportation via automobile was introduced, drivers throughout the country of Yalturia in Eastern Europe have driven on the left side of the road. Recently, the Yalturian National Congress passed a law that within 3 years, a right-hand driving convention will be adopted and implemented throughout the country. This is a major policy change for the country and will require significant public planning and project development to implement successfully and safely. Assume you are the lead engineering consultant from Halcrow Engineers, responsible for developing and describing many of these major projects. Identify six of the projects you deem necessary. State a name and provide a one or two sentence description of each project.
