Planned Qty = 1,810

Planned MP = 48

Actual MP = 45

Exp Qty = 1696

If 48 (planned) can do 1,810 (planned), 45 (actual) is expected to earn 1696. But you only achieved 504 (actual/earned value). What factor/s have affected your productivity?

These consepts are derived from Earned Value Management:

Planned quantity = the amount of the budgeted work planned to be completed in a period, or to date.

Earned quantity = the amount of the budgeted work actually achieved in a period or to date (measured using the same basis as the budget). In your example ony 28% of the planned work was achieved.

Actual quantity = the number of welding hours actually booked against the job in the same period or to date..... This activity is a total mess!!
