Brazing Versus Welding

Brazing and welding are heat treating processes that join pieces of metal together. The primary difference between the procedures is that brazing joins pieces together by melting a filler metal that distributes between the entire connective surface, whereas welding joins pieces together at narrow points by melting them together using a filler metal. When it comes to joining pieces of stainless steel via heat treating, there are important reasons to use brazing instead of welding.

Assembly Joints Are Stronger

Welding creates a strong joint when workpieces that have a narrow point of contact are joined together. However, when workpieces are joined together across a wide point of contact, brazing is preferable. The filler metal distributes between the workpieces and forms a strong bond.

Assembly Joints Are Cleaner

Because it bonds workpieces together by melting them, welding can create messy looking joints that are not suitable for stainless steel assemblies that need a neat, clean appearance. When it is properly performed, the brazing process creates neat, clean joints that have a secure bond.

Better for Thin Work Pieces

Brazing in a controlled atmosphere heats workpieces in a uniform manner, and generally exposes assembly joints to less heat than welding. Thus there is a lower chance that thin workpieces will warp. Steel treating workpieces in a furnace helps to ensure uniform heating.

Better Processing Speed

Because it requires both the base metal and filler metal to melt, welding is a steel treating procedure that generally takes longer to complete than the brazing process. If you have a large work order, forming assemblies using brazing should result in a faster completion time.

If you need assistance with steel treating, Franklin Brazing can help. We have over 40 years of experience in brazing various alloys of steel. When it comes to connecting pieces of stainless steel via heat treating, brazing frequently produces stronger, cleaner joints, has less of a tendency to warp thin workpieces, and finishes orders in a shorter period of time.
