Re: [MW:34477] Re: Argon Gas Generator

Hi All,

Case details: 

Tube sheet base material is SA-266 2/4N

Explosion bonded Cladded face (10mm) with - CrNi 90/10.

Tube material =  SB-111UNS C70600 (CuNi 9010), FINS-ALUMINIUM

Question: What will be the weld material for strength welding in between cladded face material (CrNi 90/10) to  SB-111UNS C70600 (CuNi 9010).

Vendor proposed silver brazing, need help to evaluate it and to avoid any expected repair after operation of HEX. What should be the weld filler material?

Hello All,

As you might be already aware, the price & demand for the Argon is increasing rapidly and we have to find a suitable option as a replacement especially for Gas Arc Welding.

So one of the options I am looking at present is to replace the cylinders with an Argon Generator.

If anyone has any inputs for setting up Argon Generator at site & the pros and cons of it please share.

If anyone has the same experience on setting up the same, please provide the details of the suitable supplier.

Regards,

Best regards,
