How is proper arc length justified?
Length of arc: The correct arc length varies with each electrode and application. As a good starting point, arc length should not exceed the diameter of the metal portion (core) of the electrode. For example, an 1/8-inch 6010 electrode is held about 1/8 inch off the base material.
Why is it important to maintain the correct arc length during welding?
Arc length is critical in determining the arc energy density during TIG welding. For the TIG welding of Mg alloy, the arc length has more impact on the weld penetration and weld surface shape. Moreover, for both short and long arc lengths, the penetration depth increases when activating flux is used.
How does the arc length affect a weld?
How DOES the arc length affect a weld? Arc length is the distance between the welding nozzle and the metal you’re welding. A longer arc length will result in less shielding gas, a weaker weld, and cause the welder to spit and sputter the wire.
How does arc length affect the welding?
What can happen if your arc length is too high or long?
An arc length that is too short will create greater potential for the electrode sticking to the base material. Excessively long arcs (too much voltage) produce spatter, low deposition rates, undercuts and often leaves porosity. Too long of an arc length will create excess spatter in the weld joint.
Why is arc length important in welding?
Arc length is critical in determining the arc energy density during TIG welding. For the TIG welding of Mg alloy, the arc length has more impact on the weld penetration and weld surface shape.
What does arc length mean in welding?
describes ‘arc length’ as the “distance from the tip of the welding electrode to the adjacent surface of the weld pool”.
What is the effect of arc length?
The arc length in GTAW is usually taken to be the same as the separation distance between the electrode tip and the workpiece. The effect of increasing this distance is to decrease the heating efficiency of the arc and the fusion and penetration level.
What is the effect of long arc in welding?
Arc welding is a constant current process, but the arc length has an effect on voltage. Reducing the arc length will decrease the voltage, and this reduces the heat in the weld. Increasing arc length will increase the voltage.
