Brazing is a thermal joining process in which two pieces of base metal are joined by a molten brazing filler metal which is drawn between them by capillary action. The process can be used to join most metals and alloys commonly used in engineering. A brazing filler metal has a high melting temperature, which is nevertheless lower than the melting point of the metals being joined. Brazing can join pipes, rods, and metal pieces which fit tightly against each other without large gaps; it can even join tungsten carbide, ceramics, and similar non-metallic materials.
Well-brazed joints are as strong as their parent-metal pieces and can withstand demanding service. With smooth, neat fillets, they have good electrical conductivity.
The welding of metals differs from soldering and brazing in that the joint is made without adding a lower-melting-point material (e.g. solder); instead, the pipe or tubing material is partially melted and the fitting and piping are directly fused. This generally requires that the piping and fitting are the same (or compatible) material. Skill is required to melt the joint sufficiently to ensure good fusion, while not deforming or damaging the pieces being joined.
Properly welded joints are considered reliable and durable. Pipe welding is often performed by specially licensed workers whose skills are retested periodically. For critical applications, every joint is tested with nondestructive methods. Because of the skills required, welded pipe joints are usually restricted to high-performance applications such as shipbuilding, and in chemical and nuclear reactors.
Adequate ventilation is essential to remove metal fumes from welding operations, and personal protective equipment must be worn. Because the high temperatures during welding can often generate intense ultraviolet light, dark goggles or full face shields must be used to protect the eyes. Precautions must also be taken to avoid starting fires caused by stray sparks and hot welding debris.
