Formula for calculating welding wire amount in CO2 gas shielded welding
I want to know how long welding seam I weld, how long welding wire I use, and how to calculate. It's best to have a formula. Suppose I weld a 1m fillet weld, I use 1.0 welding wire, and the height of the welding angle is 5mm. How long welding wire do I use?


The formula is not easy to use. I have experience formula, which a welding engineer should know, not a worker master needs to master
Q=KVP
K is the loss coefficient, generally 1.5-1.8
V is the volume to be filled
P is the steel density of 8kg / m3
It can also be calculated as follows: 3.1415926535798932 * 0.5 * 0.5 * L * a = 5 * 5 * 0.5 * 1000
L=5*5*0.5*1000/(3.14*0.5*A)
L=7961.8/A
A is the utilization rate of welding wire for secondary arc welding, which is about 0.9
So l = 8846mm
About 9 meters



Calculation current formula of CO2
How to calculate the current of gas shielded arc welding? Please send the formula in more detail, the better (it's better to give an example)


If you want accurate data, you don't need it at all. Because with the change of your welding position, the resistance changes. When the voltage is constant, the current also changes. I don't know if you want the parameter of welding current and voltage. Generally, V (voltage) = 0.04xa (current) + 16 It means that if you have a current of 300A and a voltage of 300x0.04 + 16 = 28V, you can weld by adding 2V or subtracting 2V on the basis of 28V. It is recommended that your welding current should not exceed 300A. If it exceeds 300, the fusion is not good. It is best to control it at 260-280. Of course, it depends on the thickness of the plate
