Brazing joins parts by heating them to more than 840°F and applying a filler metal that has a melting temperature below that of the base metal. Filler metal flows into the joint by capillary ...

The processes of brazing, soldering, and welding are often miscategorized as all being welding. In the process of welding, both the edge of the base metal and the filler metal are melted. During ...

Brazing and soldering practices are one of many areas in the HVACR field where what is commonly practiced isn’t what’s best, and what’s taught doesn’t apply in all cases. Let’s start with the basics.

Welding is only one part of metalworking. You also can cut steel, using oxygen/acetylene equipment with a special head called a cutting torch. Cutting torches come as part of many consumer-grade gas ...

Although torch brazing is the most widely used brazing method, finding a skilled operator for the process is a difficult task for many manufacturers. Moreover, it elevates regulatory and safety ...

Multiple tool inserts, typically between 40 and 60, are usually brazed individually onto a single drill bit, especially when used in down-hole fixed-cutter, hammer, or rock drill rebuild and ...

This article was updated March 7, 2023. It was originally published Dec. 9, 2004. Engineers have an impressive array of ways to join two pieces of metal including adhesives, nuts and bolts, and a long ...

Skipping any of the basic brazing steps can lead to pipe joint failure. Strong brazed joints in high-pressure pipes are critical to lasting, leak-free performance. However, brazing is not always given ...

Brazing has emerged as a critical methodology for joining dissimilar materials, most notably metals and ceramics. This technique utilises a filler metal, which melts at a temperature lower than that ...
