Enter the ppm of phosphorous, antimony, tin, and arsenic of the filler metal into the calculator to determine the x-factor.
X Factor Formula
The following formula is used to calculate an X factor for welding.
X = (10*P + 5*Sb + 4*Sn + As) / 100
- Where X is the x-factor
- P is the amount of phosphorous (ppm)
- Sb is the amount of antimony (ppm)
- Sn is the amount of tin (ppm)
- As is the amount of arsenic (ppm)
X Factor Definition
What is an x-factor for welding? An x-factor is a term used in welding to describe the metal filler or weldment’s resistance to brittleness or loss of toughness when the weldment is held.
How to calculate an X factor?
- First, determine the amount of phosphorous.
For this example, there is 10 ppm of phosphorous.
- Next, determine the amount of antimony.
For this example, there is 20 ppm of antimony.
- Next, determine the amount of tin.
For this problem, there is 15 ppm of tin.
- Next, determine the amount of arsenic.
For this example, there is 5 ppm of arsenic.
- Finally, calculate the x factor.
Using the formula, X = (10*10 + 20*5 + 15*4 + 5) / 100 = 2.65
