Differences Between Brazing and Welding

Understanding Different Techniques in the Welding Field

At Advanced Career Institute, we often get asked the difference between brazing and welding. And while most people have a basic understanding of what welding entails, the same cannot be said with brazing. Many people use the two terms interchangeably, while some have never even heard of the term brazing at all.

Welding vs. Brazing

Welding is the joining of two or more objects, usually comprised of metal, using heat to melt and fuse the parts together.

Brazing is also used to join two or more objects together with heat. The difference from welding, however, is that the items are fused together by a filler material that is melted and flowed between them.

Welding is typically used to form a stronger bond between the pieces being joined, while brazing is used to join two different types of materials.

Welding and Brazing Techniques

There are several welding and brazing techniques. Welding techniques include:

  • Shielded metal arc welding (SMAW): This is one of the simplest techniques and is used when an electrode forms an arc between it and the metals. SMAW can be used on uncleaned metal, saving time for the welder.
  • Gas metal arc welding: This method is similar to SMAW in that the source of heat is from an arc between the electrode and the metals. The difference is that a gas-shield protects against contaminants in the air. This method is used due to its fast welding times, however, the materials do need to be cleaned prior to work.
  • Gas tungsten arc welding: This technique uses tungsten rods to produce the arc. It is primarily used on thinner materials, or where aesthetics are concerned.

Common brazing techniques include:

  • Torch brazing: This is the most common technique, and is used for smaller or specialized projects.
  • Furnace brazing: This is a semi-automatic process that is typically used to produce large quantities of brazed objects, usually in industrial settings.
  • Silver brazing: This method uses silver alloy for the filler. Silver brazing is often used in the tool and railway industry.
