Welding refers to a wide variety of processes in which metals are joined by fusion. The metal at the interface of two or more parts is melted or fused by application of intense, localised heat. A ...

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 best clearance between the two metal parts being brazed is a close one - usually .001 inch to .003 inch, and generally not more than .005 inch. If the clearance is smaller than .001 inch, there ...

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 ...

Friction welding can often make an excellent alternative to brazing. Friction welding overcomes several of the variables associated with brazing that can affect bond integrity. Some of these include ...

Remember when copper was commonly used in mobile air conditioning? Hans Fernqvist does. He’s a leading technical expert on climate AC systems at Volvo Car Corp. and has been actively involved in the ...

This program establishes the minimum safe working procedures and guidelines for welding, cutting, brazing, grinding, soldering, and any other similar operation on Northwestern property. It also covers ...

Welding Handbook, Volume 3, reflects the dramatic changes brought into welding processes over the past decade due to the emergence of new welding techniques and advanced materials. Included are ...
