Fast coppering of steel wire


(1998)

Q. WE ARE LOOKING FOR CuSO4 CHEMISTRY TO COAT STEEL WIRE WITH COPPER, AT THE OUTPUT OF STEEL WIRE DRAWING MACHINE WHICH DRAWING THE WIRE AT 30 METERS PER SECOND. THIS HIGH SPEED WIRE DRAWING APPLICATION NEED A FAST ACTING COPPERING SYSTEM AS WELL.

WE WOULD APPRECIATE YOUR HELP.

SINCERELY YOURS,

A. I assume you are talking about an immersion copper process when you say it should be CuSO4-based. I'm not aware of proprietary immersion coppering processes, but certainly the higher the concentration of copper, and the warmer, and the more active the agitation, the faster it will plate.

A. I think that there is a process for immersion copper plate. It is used to copper plate ground rods for houses and etc. I doubt that any immersion process will be able to meet that speed requirement. I sort of doubt that an electrolytic process can meet it. It would require a very long tank or awesome agitation and an extremely high current and probably warmer tank temps.

A. Our Company designs and manufactures equipment for surface treatment in a variety of industries. We have worked in the CO2 weld wire industry. Your requirement is extremely challenging...and requires optimal performance from several interdependent variables such as chemistry, drawing equipment, dies, cleaning, lubrication, and surface treatment equipment. Theoretical possibilities are not always practical on the factory floor. Good luck.

A. IT IS CONVENTIONALLY POSSIBLE TO COAT ANY STEEL BY METHOD OF DEPOSITING COPPER BY DIPPING IN COPPER SULPHATE SOLUTION. MY EXPERIENCE IN COATING INDUSTRY FOR BOTH CO2 WELDING WIRE, SAW WIRE, TIRE BEAD WIRE WITH SYSTEM FROM GERMANY, ITALY, FRANCE. ENGLAND, JAPAN AND USA DO NOT GUARANTEE A SYSTEM WHICH CAN RUN AT A SPEED OF ABOVE 25 MTRS /SECOND .

THE SYSTEM OF COATING DEPENDS ON HOW CLEAN THE WIRE SURFACE IS, HOW GOOD THE COATING CHEMICALS AND ADDITIVES , AND HOW MUCH COATING IS REQUIRED ON THE SURFACE EXPRESSED IN GRAMS.AND ALSO ON THE SIZE OF THE WIRE VIZ DIAMETER OF WIRE.

HAVING WORKED IN THIS LINE FOR MORE THAN 25 YRS AND ESTABLISHED GOOD RESULTS IN INDIA AS WELL AS INDONESIA OF PLANTS IN THE ORDER OF 3000 TONS PER ANNUM CAPACITY WOULD LIKE TO SHARE MY EXPERIENCE. In MY LAST ASSIGNMENT WE HAD USED ELECTROLYTIC PICKLING WITH LEAD ANODES AND WERE ABLE TO ACHIEVE ONLY 10 MTRS PER SECOND.

I HAVE REALLY YET TO COME ACROSS A SYSTEM WHICH CAN CONSISTENTLY RUN AT HIGH SPEED IN INDUSTRIAL SETUP WITHOUT UPSETTING THE QUALITY OF END PRODUCT. WITH BEST WISHES.

Q. Dear sir,

Is there any passivation compound available for copper coated steel wire to increase its shelf life without affecting its weldability?

Is it possible to give strike solution with dipping process before the wire enters the main copper coating tank? Does it help in improving the coating?

RFQ: I HAVE SUCCEEDED ON COPPER COATED WIRE DRAWING PROCESS. IT'S AN ELECTROLYTIC METHOD. FOR THE ABOVE DRAWING WE USED CONVENTIONAL WIRE DRAWING MACHINE, SO THE PRODUCTIVITY IS VERY LOW. BUT WE ACHIEVED VERY HIGH QUALITY. WE ARE LOOKING FOR WIRE DRAWING MACHINE PARTICULARLY COPPER COATING ONLY. EXPECTING YOUR ADVICE. THANK You.

RFQ: Dear sir,

I am a production manager of CO2 manufacturing company, I need your help. Where can I purchase your additive acid? i.e., candor additive acid for copper coating process? Five years ago we were using your candor acid, but my former purchaser cannot purchase at the moment, I don't know why, if you have this product, please respond to me.

Thank you

Q. Hello,

My search for free advice has brought me to this forum! Our plant in Pakistan is manufacturing special stick welding electrodes for a couple of years. We are looking at extending our product range. Our next range of products include CO2 MIG wire and stainless steel MIG wire. Currently I am looking for equipment providers and also advice on each step of the process e.g. starting from MS wire drawing to pickling, copper coating and precision winding in case of CO2 MIG wire. I know I am asking for free advice but would appreciate helpful guidelines.

Best regards

A. Hi, Jawwad.

This site is about metal finishing, so it doesn't cover wire drawing or precision winding, but it will include advice for pickling through copper coating. You can find vendors in our Capital Equipment directory and our Used & Surplus directory if they don't contact you. I don't know enough about the CO2 process to be able to help you, but hopefully another reader will.

Q. Dear Sir,
We would like to know if there are any additives which are added into Copper Sulphate for manufacturing CO2 Mig Wire Coating.
