Re: [MW:19060] Mode of Metal transfer for GMAW

Modes of Metal Transfer:

The mode or type of metal transfer in MIG welding depends upon the current, arc

voltage, electrode diameter and type of shielding gas used. In general, there are

four modes of metal transfer.

 

1.     Dip transfer

2.     Globular transfer

3.     Spray transfer

4.     Pulsed arc transfer.

Since, constant voltage power source is being used, transfer mode depends up on voltage
setting and all the relevant parameter settings are enclosed along with for your study.

As mntioned therin marginal changes could be carried out since there is wide margin in
the amperage setting which  in turn depends on size of wire being used and position of welding.

Hope the details given will be of use to you.

Towards down hand fillet, you can use  globular or spray arc transfer depending up on metal thickness, size of the wire, no. of passes used in case of fillet being heavy.

Dear Expert,

Can any one tell me that what are the metal transfer mode available for GMAW and what type of metal transfer is suitable for down hand bottom fillet welding in MAG/GMAW
