Product Description

CuSi-A CuSi3 CuSi 3 Laser brazing welding electrode rod

it  is a copper based filler metal that contains 3% Silicon and trace amounts of manganese, tin and zinc. It is used primarily for oxyacetylene welding of copper, copper-silicon and copper-zinc metals to themselves and to steel. Silicon Bronze is excellent for plain or galvanized steel sheet metal as well as other coated steels. It is also used for surfacing areas that are subjected to corrosion. The Oxyacetylene gas flame should be slightly oxidizing. Keep the weld puddle small in order to promote fast solidification and minimize cracking. A high boric acid flux should be used both before and during welding. Preheat is NOT recommended.

Note:

1.Before welding the oxide,oil and other contaminants on the welding edge of the workpiece and welding wire surface must be cleaned,therwise it will lead to porosity, slag and other defects, so that the performance of the weld is reduced.

2.The addition of tin expands the temperature range between the solid and the liquid phase.In order to reduce the thermal tendency in small pool and fast welding is appropriate.

3.T tungsten inert gas arc welding, the workpiece requires preheating,only with the flat position welding
