Hi,
With proper selection of coated electrode and qualified WPS / Qualified welder, you can weld SS (any grade) even to radiography quality. Coated electrodes are available in the market.

Hi
What type of joint are you talking about ?
If it is a single sided joint without access from other side, root + hot pass has to be welded by TIG. You cant use SMAW directly.
If there is access from other side and chip back is possible you can go for SMAW like double V full penetration joint..
Also you can weld partial penetration joint root with SMAW..

Hi there,
One of our manager wants to Develop WPS for SS which can utilize
SMAW –root. I do not see it is common in SS welding. But there may be something
can make us competitive against GTAW root.
Does anybody have thought to share with me?
Thanks in Advance..!
