How To Solder Galvanized Sheet Metal

Unlike welding soldering allows the user to bind small pieces of metal together and is commonly used in the manufacture of circuit boards.

How to solder galvanized sheet metal.

Soldering and adhesive joining. While soldering is useful for many purposes it has limitations. Zinc sheet part 5 soldering how to solder together two sheets of zinc. I recently learned the hard way to obtain a sample of the metal and try soldering before fabricating.

Rolled steel sheets are galvanized by a continuous electrolytic plating process. Because the galvanized metal is designed to be resistant to outside harm soldering pieces of steel that have been galvanized can pose a problem if done improperly. Beware look alike products like zap or zincalume these cannot be soldered either. Low temperature soldering and adhesive joining are processes for joining galvanized steel that do not damage the zinc protection.

I think it depends on the alloys used in the galvanizing. However some galvanized sheet metal is impossible to solder. Tradesmen often use brazing or welding instead to create stronger joins between the metals. Soldering glues the pieces of metal together by melting a softer metal to act as an adhesive.

This process permits control of a uniform plating as a thin layer. Galvanized steel is a protected variety of the metal using the process of galvanization to prevent and repel corrosion.
