During a TIG welding process, the arc current and arc voltage were 50 ...
To determine the welding current in the second TIG welding process, we need to understand the relationship between welding current, welding speed, arc voltage, and heat input.
The heat input in welding is given by the formula:
Heat Input = Arc Voltage x Arc Current x Welding Speed
We are given the values of arc voltage (60 V) and welding speed (150 mm/min) in the first process. We can calculate the heat input for this process as follows:
Heat Input = 60 V x 50 A x 150 mm/min = 450,000 W/min
Now, in the second process, we are given that the welding speed is 120 mm/min, and we need to determine the welding current. Since the arc voltage and heat input remain the same, we can use the formula to calculate the welding current:
Welding Current = Heat Input / (Arc Voltage x Welding Speed)
Plugging in the values, we get:
Welding Current = 450,000 W/min / (60 V x 120 mm/min)
Simplifying the units, we have:
Welding Current = 450,000 W/min / (60 V x 0.12 m/min)
Welding Current = 625 A
Therefore, the welding current in the second TIG welding process is 625 A.
However, the correct answer given is option 'A' which is 40.00 A. It seems there may be an error in the question or the correct answer option provided. The calculation shows that the welding current should be 625 A, not 40.00 A.
The heat input in welding is given by the formula:
Heat Input = Arc Voltage x Arc Current x Welding Speed
We are given the values of arc voltage (60 V) and welding speed (150 mm/min) in the first process. We can calculate the heat input for this process as follows:
Heat Input = 60 V x 50 A x 150 mm/min = 450,000 W/min
Now, in the second process, we are given that the welding speed is 120 mm/min, and we need to determine the welding current. Since the arc voltage and heat input remain the same, we can use the formula to calculate the welding current:
Welding Current = Heat Input / (Arc Voltage x Welding Speed)
Plugging in the values, we get:
Welding Current = 450,000 W/min / (60 V x 120 mm/min)
Simplifying the units, we have:
Welding Current = 450,000 W/min / (60 V x 0.12 m/min)
Welding Current = 625 A
Therefore, the welding current in the second TIG welding process is 625 A.
However, the correct answer given is option 'A' which is 40.00 A. It seems there may be an error in the question or the correct answer option provided. The calculation shows that the welding current should be 625 A, not 40.00 A.
