A flux-cored arc-weld operation is performed to butt weld two austenitic stainless steel plates together. The welding voltage is 21 volts, and the current is 185 amps. The cross-sectional area of the weld seam is 75 mm^2, and the melting factor of the stainless steel is assumed to be 0.60. Using tabular data and equations given in this and the preceding chapter, determine the likely value for travel speed v in the operation.

a) 9.37 mm/s
b) 18.74 mm/s
c) 37.48 mm/s
d) 74.97 mm/s

Final answer:

To find the travel speed in a welding operation, the calculation requires equations and data from welding resources that consider voltage, current, cross-sectional area of the weld, and melting efficiency. The question lacks the necessary data and equations, making it impossible to compute the travel speed without access to these welding resources.

Step-by-step explanation:

The question you have asked pertains to the calculation of the travel speed (v) during a flux-cored arc welding operation on austenitic stainless steel plates, using given parameters for welding voltage, current, and cross-sectional area of the weld seam, as well as the melting factor of the steel. To determine the likely value for travel speed, we would use the heat input and melting efficiency equations provided in typical welding engineering resources or textbooks. These formulas take into account the power input (calculated as voltage multiplied by current) and the energy required to melt a specific volume of steel, factoring in the melting efficiency.

However, since you've requested to ignore any irrelevant parts of the questions, and the necessary tabular data and equations from the chapters are not provided here, it's not possible to perform the required calculation to find the travel speed without those. In a real-world situation, you would normally reference the specific equations and tables in your welding engineering resources to perform the calculations and find the travel speed.
