What does SFA stands for in welding?

In welding, SFA stands for "Specification for Welding Filler Metals." It refers to a set of standards established by the American Welding Society (AWS) that outlines the requirements for various types of welding filler materials, including their chemical composition, mechanical properties, and intended applications. These specifications help ensure consistency, quality, and safety in welding processes.


Why is brazing better than welding?

Welding would melt the base metal and filler metal while brazzing only melts the filler metal.

How brazing different from welding?

In welding, the parent metal, that is the pieces to be joined are actually melted along with the filler metal, if any. The filler metal is the same material as the parent metal. In brazing, the pieces to be joined are heated, but do not melt. Only the filler metal is melted. The filler is a brazing alloy, usually an alloy containing brass, silver, or other metals. The filler metal is not the same as the parent metal. Since brazing does not melt the parent metal, less heat is required, but the resulting joint is not as strong as a welded joint. The brazing alloy is usually a different color than the parent metal, so the joint will stand out and be visible, which can be an issue where appearance is important.


Does EW indicates the type of filler metal used for the GTAW process?

Yes, the designation "EW" in filler metal specifications indicates the type of filler metal used for Gas Tungsten Arc Welding (GTAW). Specifically, "E" denotes the electrode, while "W" signifies that the filler metal is specifically designed for welding applications. This designation helps welders select the appropriate filler material based on the base metals being joined and the desired properties of the weld.


Should filler metal be of same composition as that of base metal to be welded?

Filler metal does not necessarily need to be of the same composition as the base metal being welded, but it should be compatible to ensure a strong bond and desired properties in the weld. Using filler metal with similar or compatible properties can help prevent issues such as cracking or poor corrosion resistance. In some cases, specific filler metals are chosen to enhance certain characteristics, like strength or ductility, which may differ from the base metal. Ultimately, the choice of filler metal depends on the welding process, the materials involved, and the desired performance of the finished joint.
