Dear All,
In SMAW process, generally the polarity is DCEP(Direct Current Electrode Positive).I would like to get some advise on my following queries.
1. Is there any problem, if I am changing the polarity to DCEN in SMAW process?
2. Is this polarity change has any effect on metallurgical properties of materials comes under carbon steel family?
3. Is this polarity change has any effect on metallurgical properties of non ferrous materials?
Regards,
Limesh
