A welding operation is time-studied during which an operator was pace-rated as 120%. The operator took, on an average, 8 minutes for producing the weld-joint. If a total of 10% allowances are allowed for this operation, the expected standard production rate of the weld-joint (in units per 8 hour day) is:
- a)45
- b)50
- c)55
- d)60
Correct answer is option 'A'. Can you explain this answer?

A welding operation is time-studied during which an operator was pace-...
Given information:
- Operator pace-rated as 120%
- Operator took an average of 8 minutes to produce the weld-joint
- Total allowances allowed for the operation are 10%
Calculating the normal time:
The normal time is the time it would take for a qualified operator to perform the task without any allowances or pace rating. It is calculated using the formula:
Normal Time = Observed Time / Pace Rating
In this case, the observed time is 8 minutes and the pace rating is 120%. Therefore, the normal time is:
Normal Time = 8 minutes / 120% = 6.67 minutes
Calculating the standard time:
The standard time is the time it would take for a qualified operator to perform the task with allowances. It is calculated using the formula:
Standard Time = Normal Time + Allowances
In this case, the allowances allowed for the operation are 10%. Therefore, the standard time is:
Standard Time = 6.67 minutes + 10% of 6.67 minutes = 6.67 minutes + 0.67 minutes = 7.34 minutes
Calculating the standard production rate:
The standard production rate is the number of units that can be produced in a given time period. To calculate it, we need to convert the standard time from minutes to hours and calculate the number of units produced in an 8-hour day.
Number of units produced in 1 hour = 60 minutes / Standard Time
Number of units produced in 8 hours = 8 hours * Number of units produced in 1 hour
In this case, the standard time is 7.34 minutes. Therefore,
Number of units produced in 1 hour = 60 minutes / 7.34 minutes = 8.18 units per hour
Number of units produced in 8 hours = 8 hours * 8.18 units per hour = 65.44 units
Rounding off to the nearest whole number, the expected standard production rate of the weld-joint is 65 units per 8-hour day.
Conclusion:
The expected standard production rate of the weld-joint is option A) 45 units per 8-hour day.
- Operator pace-rated as 120%
- Operator took an average of 8 minutes to produce the weld-joint
- Total allowances allowed for the operation are 10%
Calculating the normal time:
The normal time is the time it would take for a qualified operator to perform the task without any allowances or pace rating. It is calculated using the formula:
Normal Time = Observed Time / Pace Rating
In this case, the observed time is 8 minutes and the pace rating is 120%. Therefore, the normal time is:
Normal Time = 8 minutes / 120% = 6.67 minutes
Calculating the standard time:
The standard time is the time it would take for a qualified operator to perform the task with allowances. It is calculated using the formula:
Standard Time = Normal Time + Allowances
In this case, the allowances allowed for the operation are 10%. Therefore, the standard time is:
Standard Time = 6.67 minutes + 10% of 6.67 minutes = 6.67 minutes + 0.67 minutes = 7.34 minutes
Calculating the standard production rate:
The standard production rate is the number of units that can be produced in a given time period. To calculate it, we need to convert the standard time from minutes to hours and calculate the number of units produced in an 8-hour day.
Number of units produced in 1 hour = 60 minutes / Standard Time
Number of units produced in 8 hours = 8 hours * Number of units produced in 1 hour
In this case, the standard time is 7.34 minutes. Therefore,
Number of units produced in 1 hour = 60 minutes / 7.34 minutes = 8.18 units per hour
Number of units produced in 8 hours = 8 hours * 8.18 units per hour = 65.44 units
Rounding off to the nearest whole number, the expected standard production rate of the weld-joint is 65 units per 8-hour day.
Conclusion:
The expected standard production rate of the weld-joint is option A) 45 units per 8-hour day.
