Required Duty cycle for arc welding Solution

STEP 0: Pre-Calculation Summary

Formula Used

Required Duty Cycle = Rated Duty Cycle*(Rated Current/Maximum current new add)^2
%_Required = %_Rated*(I_r/I_max)^2
This formula uses 4 Variables

Variables Used

Required Duty Cycle - Required Duty Cycle or Actual Duty Cycle is the percentage of time in a 10 minute period that a welding machine can be used at its rated output without overloading.
Rated Duty Cycle - Rated Duty Cycle is the percentage of time in a 10 minute period that a welding machine can be used at its rated output without overloading.
Rated Current - (Measured in Ampere) - Rated Current is that value which is provided against standard operation of equipment by the manufacturer.
Maximum current new add - (Measured in Ampere) - Maximum current new add is the maximum possible current flow in the given situatiion.

STEP 1: Convert Input(s) to Base Unit

Rated Duty Cycle: 1.01 --> No Conversion Required
Rated Current: 4.5 Ampere --> 4.5 Ampere No Conversion Required
Maximum current new add: 7 Ampere --> 7 Ampere No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

%_Required = %_Rated*(I_r/I_max)^2 --> 1.01*(4.5/7)^2

Evaluating ... ...

%_Required = 0.417397959183674

STEP 3: Convert Result to Output's Unit

0.417397959183674 --> No Conversion Required

FINAL ANSWER

0.417397959183674 ≈ 0.417398 <-- Required Duty Cycle

< 11 Heat Input in Welding Calculators

Net heat supplied to joint

Go Heat Required per Unit Volume = Heat Transfer Efficiency*Electrode Potential*Electric Current/(Melting Efficiency*Travel Speed of Electrode*Area)

Heat required to Melt Joint

Go Heat Required = Mass*((Specific Heat Capacity at Constant Pressure*Rise in Temperature)+Latent Heat of Fusion)

Total heat generated in resistance welding

Go Heat Generated = Constant to Account for Heat Losses*Input Current^2*Resistance*Time

Rated Duty Cycle given Actual Duty Cycle

Go Rated Duty Cycle = Required Duty Cycle*(Maximum current new add/Rated Current)^2

Required Duty cycle for arc welding

Go Required Duty Cycle = Rated Duty Cycle*(Rated Current/Maximum current new add)^2

Net heat per unit volume available for Arc welding

Go Heat Required per Unit Volume = Input Power/(Travel Speed of Electrode*Area)

Heat Transfer Efficiency

Go Heat Transfer Efficiency = Net Heat Supplied/Heat Generated

Power given Electric Potential Difference and Electric Current

Go Power = Electric Potential Difference*Electric Current

Power given Electric Potential Difference and Resistance

Go Power = (Electric Potential Difference^2)/Resistance

Melting Efficiency

Go Melting Efficiency = Heat Required/Net Heat Supplied

Power given Electric Current and Resistance

Go Power = Electric Current^2*Resistance

Required Duty cycle for arc welding Formula

Required Duty Cycle = Rated Duty Cycle*(Rated Current/Maximum current new add)^2
%_Required = %_Rated*(I_r/I_max)^2

What is duty cycle?

The duty cycle as defined by American Welding Society (AWS) is “The percentage of time in a 10 minute period that a welding machine can be used at its rated output without over loading”.
But continuous, automatic welding machines may require the welding machine to operate at 100% duty cycle. Sometimes the suggested duty cycle can be lowered for high ambient temperatures, insufficient cooling air quality and low line voltage.

How to Calculate Required Duty cycle for arc welding?

Required Duty cycle for arc welding calculator uses Required Duty Cycle = Rated Duty Cycle*(Rated Current/Maximum current new add)^2 to calculate the Required Duty Cycle, The Required Duty cycle for arc welding is the actual duty cycle, which is the percentage of time in a 10 minute period that a welding machine can be used at its rated output without over loading. Required Duty Cycle is denoted by %_Required symbol.

How to calculate Required Duty cycle for arc welding using this online calculator? To use this online calculator for Required Duty cycle for arc welding, enter Rated Duty Cycle (%_Rated), Rated Current (I_r) & Maximum current new add (I_max) and hit the calculate button. Here is how the Required Duty cycle for arc welding calculation can be explained with given input values -> 0.247959 = 1.01*(4.5/7)^2.
