What is the Globular Transfer in Welding?

The globular transfer is a mode of metal transfer across the arc where a molten ball larger than the electrode diameter forms at the tip of the electrode. On detachment, it takes on an irregular shape and tumbles towards the weld puddle sometimes shorting between the electrode and working at irregular intervals. This type of transfer usually occurs when using shielding gases other than those consisting of at least 80% argon and at medium current settings.

What is globular transfer welding used for?

While globular transfer can be used for welding, it is not generally considered the best mode of the transfer due to its potential for inconsistency and lack of fusion. For these reasons, it is typically only used in specific circumstances where other modes of transfer are not possible or practical.

Can globular transfer be used in all welding positions?

No, the globular transfer is not possible in all welding positions. It is most commonly used in the flat or horizontal position due to the fact that the molten metal can more easily fall away from the electrode in this position.

What are the advantages and disadvantages of globular transfer welding?

The advantages of globular transfer welding include its high deposition rate and good penetration. However, the disadvantages of this mode of transfer include its potential for lack of fusion, inconsistency, and electrode contamination.
