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.

I recently learned the hard way to obtain a sample of the metal and try soldering before fabricating. Low temperature soldering and adhesive joining are processes for joining galvanized steel that do not damage the zinc protection. Tradesmen often use brazing or welding instead to create stronger joins between the metals. However some galvanized sheet metal is impossible to solder.

While soldering is useful for many purposes it has limitations. 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. Soldering glues the pieces of metal together by melting a softer metal to act as an adhesive. Scott wuebber bozeman montana.

I think it depends on the alloys used in the galvanizing. For homeowners the simplest solution is an epoxy or other adhesive that is made for joining. 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.

Beware look alike products like zap or zincalume these cannot be soldered either. Rolled steel sheets are galvanized by a continuous electrolytic plating process.
