SAW FLUX REUSAGE.

[manoj john]

Dear Memebers,

We are using SAW process for Carbon Steel welding but i have doubt in reuse of flux .  My doubt is that on what basis we can reuse the electrode i am not able to find any standard or guide line for reusing.  We are reusing the fluxes mixed with 20% used and 80% new flux, is it OK and please give me some information for reusing of flux or mixing of used flux  with new flux.

Thanks in advance.

Manoj

You can not reuse the electrode as it might be consumed . For better performance same flux
could be used for twice as it is after reheating then depend upon the condition of flux 60 /40
or 70/30 new / used you can use. used flux must be cleaned.

Is it Fused flux or agglomerated  flux. Generally 1:3 (Used flux:: virgin Flux). Use flux recovery system, consult flux manufacturer

Dear Manoj,
Pls refer AWS D1.1 Cls 5.3.3.3, it is clearly
mentioned that you can use the mixture of used flux and virgin flux
but it does not affect the composition of the flux materials.

Thanks & Regards,
Bala

What is mixing  ratio of used & virgin flux, pl understand the clarifications sought for

It is recommended to add at least 20% new flux by weight to recycled flux.
