The brazing story:
ITT Industries, a leading supplier to major automakers, manufactures aluminum tubing assemblies for vehicle air conditioning components. The company makes both inlet and outlet tubes for condensers and evaporators and a tube header for air conditioning condensers.
ITT relies on brazing in a variety of different processes throughout its facility; from 2-piece assemblies to the more complex tube headers requiring up to seven brazing operations. Most involve the joining of aluminum components using paste, flux and/or preforms.
All ITT’s brazing operations are semi-automated. Aluminum tubing is joined at multi-station index tables. Steps in the process include loading the parts, application of filler metal, heating, cooling and cleaning.
Why brazing? ITT Industries’ customers, looking for a high quality, cost effective part, specify that brazing be used in the production of their tubing assemblies. In this application, brazing is the logical choice as it provides a dependable, strong joint at the most economical cost.
