I was plaanning to use Tandem SAW for 25mm thk butt joint in a shell of @3m dia.
I had gone through various literatures of reputed consumable manufacturers wherin it was mentioned that tandem SAW can be used for 15mm thickness and above. But if you see practically tandem SAW will cause distortion and ovality in thin walled shells in shop!!
Thus i am very much convinced by what Mr.Hegde has practically recommended i.e 35mm thickness and above..
