Suppose in the previous problem that a roll spotwelding operation is performed instead of seam welding. The interface resistance increases to 100 micro-V, and the center-to-center separation between weld nuggets is 25 mm. Given the conditions from the previous problem, with the changes noted here, determine

(a) the proportion of energy generated that goes into the formation of each weld nugget, and

(b) the rotational speed of the electrode wheels.

(c) At this higher rotational speed, how much does the wheel move during the current on-time, and might this have the effect
f elongating the weld nugget (making it elliptical rather than round)?
