[MW:21945] Lack of fusion in production welding - GMAW !!!

Dear Experts,

 

I face Lack of fusion problem in GMAW process in the production weld often.

WPS qualified on short circuiting mode as the torch is designed to the same.

But when I use the same current and voltage I come across Lack of fusion

The wire I use is ER316L of 1.2mm dia.Bare wire , volt not more than 19V.

 

Now I started using 23 to 26V(Spray transfer mode volt range) to overcome my issue.

Can you suggest what are the parameters I need to control to get a sound weld in the short circuiting mode.

 

Regards

Vadivel. M
