[MW:11128] QW 304: Welders

Dear Experts, 

As per ASME IX 

QW-304 Welders :

Except for the special requirements of QW-380, each  welder who welds under the rules of the Code shall have  passed the mechanical and visual examinations prescribed
in QW-302.1 and QW-302.4 respectively. Alternatively, welders making a groove weld using SMAW, SAW, GTAW, PAW, and GMAW (except short-circuiting mode)
or a combination of these processes, may be qualified by radiographic examination,

WHY SHORT- CIRCUITING MODE IS EXCEPTIONAL  ??? 

Regards.

Abhishek Ghosh
