How do you calculate electrode efficiency?
The electrode efficiency is calculated by dividing the mass of weld metal deposited by the mass of core wire consumed. The mass of core wire is less than the total mass of electrode consumed i.e. core wire + flux covering.
How do you calculate welding rod in KG?
4) Multiply weld volume by metal density (7,800 kg/m^3) to give mass of weld metal per weld (in kg)5) Multiply mass per weld by the total number of welds to give total weld metal required (in kg).
How are weld passes calculated?
Here are some things that will determine number of passes:
- Travel speed. High travel speeds equal low weld volume.
- Weave width or oscillation. The same idea applies to weave or oscillation as it does to travel speed.
- Joint configuration.
- Electrode diameter and wire feed speed (WFS).

How is welding weight calculated?
1 Calculating Filler Metal Consumption The number of pounds of welding electrodes or welding wire necessary to complete a given weld joint may be calculated by the formula: P = WL E Where: P = Pounds of electrode or wire required W = Weight per foot of weld metal L = Length of weld (feet) E = Deposition efficiency …
How do you calculate electrode consumption?
The electrode consumption per metre of welded joint is obtained by dividing the number of kg of weld metal by N, where N is the kg of weld metal per kg of electrode.
How is weld strength calculated?
How to Determine the Strength of a Transverse Fillet Weld
- σt is the tensile strength of the weld (determined by the filler metal being used) in PSI.
- F is the force the weld can handle, in other words, the strength of the weld in lbf.
- A is the effective area of the weld.
- Throat = “w” x cos 45˚ = (1/4) x (0.707) = 0.177”
How many passes on a weld?
You’ll achieve the same weld quality, but the number of passes just depends on your technique and comfort level with the orientation. The same joint in the 3G (vertical) position typically requires a minimum of three passes but would be of equal quality if it took five to six passes.
