Silicon Bronze Tig Welding Sheet Metal

Silicon bronze can be used for on plain or galvanized steel sheet metal.

Silicon bronze tig welding sheet metal.

Find something softer like silicon bronze as a filler material which is also thinner than the base metal as well. Silicon bronze welding alloy. Silicon bronze filler metal was years ago referred to as everdur and it can be used to join base metals of steels and cast iron to copper brass and bronze. Otherwise you may not be able to do the joints properly due to overheating issues.

While er70s 2 filler metal is a common choice for steel another popular option for welding sheet metal is silicon bronze. It s nice for sheet metal work because the lower melting temps means less heat which equals less warping when compared to tig with say an er70 rod. If you prefer to have more control picking a pointed electrode might be a better idea for tig welders. While the melting point of steel is around 2700 f.

Silicon bronze filler metal is made up of mostly copper with 2 8 4 silicon and and trace amounts of manganese tin and zinc that lower the melting point to around 1900f. Lower melting point the silicon bronze rod s lower melting point makes it ideal for joining together thin sheet metal galvanized steel and nuts and bolts too. Silicon bronze is a copper based filler metal primarily used for mig tig and oxyacetylene welding of copper. It is softer and finishes well while reducing the heat required to weld it.

Tig welding with silicon bronze is technically tig brazing because usually the base metal being welded brazed has a much higher melting point than silicon bronze filler rod. Silicon bronze is also frequently used in gtaw brass welding of coated sheet steels. Copper silicon and copper zinc base metals to themselves and to steel. The melting point of silicon bronze tig rod is between 1800 and 1990 f.

3sib gtaw tig description. It can also be used for surfacing areas subjected to corrosion. Silicon bronze is best known for welding plain or galvanized steel sheet metal in the manufacturing of steel cabinets metal furniture and ductwork.
