ABSTRACT:
An electrowinning anode is formed by tightly joining a sheet of lead anode material to a copper busbar using solder to fill the joint. The busbar is optimally coated with a tin alloy by dipping the busbar into the alloy prior to being joined with the sheet. A lead coating is electrodeposited onto the busbar and the soldered joint to provide a complete metallurgical seal and good resistance to acid corrosion.
