Tungsten electrode spheroidization is an important phenomenon in welding, and its “quality” depends on the specific welding process and application requirements.
Advantages of End Spheroidization:
In AC welding (especially aluminum-magnesium alloy welding), the spheroidization of the tungsten electrode can stabilize the arc and avoid excessive ablation of the electrode head. The spherical end allows for more uniform arc distribution, reducing local overheating and extending electrode life.
The spheroidized end is conducive to the formation of a wide and uniform weld, which is suitable for the heat input requirements of AC welding.
Disadvantages of End Spheroidization:
In DC welding, especially for fine welding or when a concentrated heat source is required, the spheroidization of the electrode will lead to arc diffusion and heat dispersion, which is not conducive to the formation of sharp and concentrated arcs, affecting the depth and formation of the weld.
Excessive spheroidization of the electrodes can also lead to arc initiation difficulties and arc instability.
