welding stainless steel sheets

[structural1]

Dear Friends
Thanks for your answers to the precedent thread.
I need to get information about continuous welding of stainless steel sheets (304 or 316) of a thickness from 1mm to 3 mmm thick for a decorative purpose and not structural (no pression or tension is applied). The surface to be welded can be either flat of round.Cladding with stainless steel sheets is the purpose without any separation line and without distortion due to heat.
I need also to know if there is any paste that can be used to fill a separation line between 2 stainless steel sheets that gives the same brushed finish for the sheets?
Regards.

For your application, consider brazing instead of fusion welding (you will obtain a better appearance and non structural joint). BAg-21 filler metal with a suitable flux is recommended. Do not fusion weld 304 and 316 stainless steel, these not stabilized, not low carbon austenitic grades are susceptibles to intergranular corrosion due the sensitization produced by the fusion weld heat.
Good Luck !

There are stainless steelm filled epoxy adhesives available. However, the joints will have to be sanded/finished to match the brush finish on the architectural stainless sheets.
