Re: [MW:6560] Conflict about heat available on electrode/work for the SMAW & GTAW process even having same polarity

Can you please elaborate for the benefit of whole group as all the people will not have the opportunity to look into the ASM handbook...seldom used at site.

Regards.

Maulik,

It is not the conflict.

Pls understand the difference between the Thermionic & Non-Thermionic cathodes,

That will explains the heat distribution. Pls go through the topic of Arc Physics in ASM Welding Handbooks

Dear all,


1. For SMAW-DCEN-2/3 heat to the electrode.

2. For GTAW-DCEN-2/3 heat to the work.


Why this is conflict?
Theoretically more heat is produced where the bombardment of electrons
is carried out.
Please give me clarification justification with proper evidence.

Maulik H. Thakkar
