Automotive Parts Supplier Acquires Vacuum Furnace To Conduct Aluminum Brazing Tests

An automotive supplier has acquired a vacuum furnace for brazing aluminum components. The VAB furnace was designed according to the client’s guidelines and will be used by the R&D department to conduct development tests in the field of aluminum vacuum brazing.

SECO/WARWICK previously provided vacuum technology systems to the automotive parts manufacturer and built the VAB furnace based on the design of a single-chamber VECTOR furnace.

“Orders requiring a specific approach always make us happy, because it builds, inspires, and develops both our body of knowledge and the technology. This project was certainly a challenge for the entire SECO/WARWICK Team, because the partner’s assumptions, in relation to the requirements placed on our furnace, were really high,” said Maciej Korecki, vice president of the vacuum furnace segment at SECO/WARWICK. “They required a very complicated and individual solution in the form of a cuboid shape of the heating chamber equipped with flat, large-surface heating elements. They were arranged in twelve independent temperature control zones, ensuring very high dynamics of load heating and ideal temperature uniformity.”

“We were tasked with creating a VAB furnace with unique solutions: a special square heating chamber equipped with flat heating elements made of Inconel 600 material, arranged in twelve independent temperature control zones” said Lukasz Chwiałkowski, sales manager at SECO/WARWICK.

The Basics of Vacuum Aluminum Brazing

Source: Signature Vacuum

When you are a new heat treater, there are really only three things you want to know to get your bearings: What is it? How does it work? Why does it matter? That's it. What does that mean when we discuss "VAB"?

This best of the web article walks you through the three questions mentioned above, several advantages of vacuum aluminum brazing, and heating control.

An excerpt:

"The dwell time (soak) at braze temperature must be minimized as melted filler metal is vaporizing in the low pressure (high vacuum) environment. Too much filler metal vaporization can result in poor joint wetting and subsequent loss of joint strength and sealing ability. After the final brazing soak is complete, a vacuum cooling cycle follows, which stops material vaporization and solidifies the filler metal."
