Re: [MW:12373] Welder Qualification for MIG welding(Short-circuiting transfer)

Hi, In GMAW-Short circuit mode,There will be low heatinput,low voltage range and thust it leads to Lack of fusion(Side wall fusion) and it may not identify by RT. Thats why Code need to do Bend test for this particular transfer mode.Bend test clearly identify the lack of fusion.

What could be the exact technical reason behind this requirement?????? Can any body explain me at the earliest please!!!!
