- Curve A of Fig. 3 showsthe approximate maximum pH which should be employed for the bath, correlated with the chloride normality of the bath, in ordere that the weld joint or joints will not preferentially corrode.
- the maximum pH for preventing preferentiall corrosion of the weld is about pH 2.0.
- the maximum pH is about 3.5
- the maximum pH is about 4.
- nickel plating baths of varying compositions were employed.
- aqueous platingbaths used were those having the followin g compositions:
- the temperature of the electro-plating bath may be varied over a wide range of temperature, such as from about F. to the boiling point of the bath. However, for best results, I preferto employ a bath temperature of F. to 140 F., i. e. about F.
- Example I An electrolytic nickel anode was prepared by welding together pieces of electrolytic nickel with a weld metal having the following'composition:
- the ⁇ welded electrolytic nickel anode was used as an anode in an aqueous nickel electroplating bath containing 300 grams per liter of nickel sulfate,'45 grams per liter of nickel chloride and 30 grams per liter of boric acid.
- the chloride normality of the bath was about 0.4.

- Nickel Bala The weldedA electrolytic nickel anode was used as an anode in an aqueous nickel electroplating bath containing 285 grams per liter of nickel sulfate, 112 grams per liter of nickel chloride and 40 grains per liter of boric acid.

Because the weld metal employed by the present invention does not corrode preferentially when in contact with electrolytic nickel and subjected to the electrolytic and/or corrosive effects of a nickel plating bath'correlated in pH and chloride normality as hereinbefore set forth, it is believed that the resistance to preferential corrosion of the weld metal is due to its more noble anode potential.
- the weld metal has a. more noble anode potential than electrolytic nickel at a bath pH not exceeding about 3.5 whereas with a bath pH exceeding about 3.5, the electrolytic nickel has a more noble anode potential than the weld metal.
