Application:
Tubing assemblies for air conditioning components produced by ITT Industries, Fluid Handling Systems.
The soldering 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.

- Brazing in action.
- Aluminum paste or flux is dispensed in pre-measured amounts.
- One of several semi-automated systems at ITT
ITT's automotive 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.
