Question
During a TIG welding process, the arc current and arc voltage were and , respectively, when the welding speed was . In another process, the TIG welding is carried out at a welding speed of at the same arc voltage and heat input to the material so that weld quality remains the same. The welding current (in A) for this process is
Correct answer
(A) 40.00
Solution
Heat input per unit length is given by , where is arc voltage, is arc current, and is welding speed.
Given that the heat input () and arc voltage () remain the same for both processes, we have:Substituting the given values:Thus, the welding current for the second process is .
