ESW strip cladding with NA5 from Lincoln

[HERVE34]

Hi everybody,

Does anybody have somme experience in setting of a NA-5 Control from lincoln for electroslag strip cladding ?

I'm looking for more information on the start module and crater module (benefits and settings) ?

Thanks

Its not that difficult, lots of US fabricators now do it routinely and parameters don't vary much for a given alloy. Lincoln can fix you up with a strip cladding head (not sure if they make it themselves) as well as parameters. Everything but the strip head remains standard equipment, although travel speed will be relatively slow; make sure your manipulator can handle it. I recommend the start and crater modules for all SAW usage; you will figure out the settings pretty quickly during trial welding. Your goal is to achieve reasonably low dilution, good tie-in, and as uniform a finished surface as possible.

I would look to premium European or Japanese vendors for consumables.
One tip - cut your strip at 45° for a smooth arc start.

thanks for reply, I cut the strip at 45°.I want a smooth start because I need to grind each start to have a slope before close the loop ( i'm working on a cylinder in one pass and one layer). When using start module the strip feed is not progressive ...
