During a TIG welding process, the arc current and arc voltage were $50$ $A$ and $60$ $V$, respectively, when the welding speed was $150$ $mm/min$. In another process, the TIG welding is carried out at a welding speed of $120$ $mm/min$ at the same arc voltage and ... so that weld quality remains the same. The welding current (in $A$) for this process is $40.00$ $44.72$ $55.90$ $62.25$
