Special Issue in cooperation with
EABS and Solvay Fluor GmbH announce the eleventh annual presentation of their joint technical training seminar entitled:
The theory and practice of the flame- and furnace-brazing of aluminium
Dates: 4th and 5th September 2012
Purpose of the Seminar:
These are: This technical training seminar will be presented at the Conference Centre and laboratories of Solvay GmbH, in Hannover, Germany. It will provide information concerning the manufacturing practices commonly used for brazing operations and, in particular, will address the three fundamental aspects of the industrial-scale brazing of aluminium.
- The flame brazing of aluminium.
- The Controlled Atmosphere Brazing (CAB) of aluminium heat exchangers with non-corrosive fluxes (NOCOLOK® Flux).
- The methodology of how to ensure that the brazing process selected is, indeed, the one that represents "best practice".
Who should attend this two-day seminar
- Technical staff who need to have a specific understanding of either one or both of the fine details of the technology of the brazing of aluminium with flames, and/or the NOCOLOK® furnace brazing process.
- Design and production engineers who are fabricating, or who intend to fabricate, aluminium pipe-work assemblies and/or condensers and/or evaporators.
- Production Engineering Department Managers whose duties include day-to-day responsibility for the brazing of aluminium.

- The seminar will be presented in the English language
- Both Solvay Fluor GmbH and EABS will distribute their information to delegates at the event. All delegates will be given a folder when they arrive at the lecture theatre. This will contain brief notes on each of the topics that will be covered by the presenters during each of the two days of the seminar.
- EABS will arrange hotel accommodation required by delegates to the seminar. A sufficient number of rooms have already been booked at the Hotel am Stadtpark. This hotel is about a seven-minute walk from the Solvay Conference Centre where the seminar is to be held. To ensure that the hotel booking arrangements run smoothly, delegates are kindly asked to enter their booking requirements on the Hotel Booking Form sent with this note. The room charge will be € 93 per room, per night, and this includes the cost of breakfast.
- Please note that Delegates will be responsible for settling their own hotel bill when they check out from the hotel.
- It is very important that Annette.Daubner@solvay.com is advised in cases where a Company who has already booked a place or places at the Seminar needs to replace one or more delegates with another member of their staff. This information must reach Annette before the "new" delegate or delegates arrive at the Hotel am Stadtpark. This is because Solvay has to confirm to the hotel the name of each delegate when they make the room reservation for a specific delegate. Consequently, if another person arrives whom the Hotel is not expecting they have no option but to offer the ‘unexpected’ delegate any other room that is currently available. This means that the room that was originally booked on behalf of a previously named delegate remains unoccupied overnight and, according to the Terms and Conditions of the Hotel, because it was Solvay Fluor GmbH who booked the room, the overnight charge for the empty room is billed to them! In such cases Solvay has to pass this charge on to the Delegates Company. This is why it is so important to tell Mrs Daubner of any change of a delegate that needs to be made as soon as it is known, please!
- The seminar will begin at 09:00 on Tuesday 4th September 2012, and is expected to finish at about 16:45 on Wednesday 5th September 2012.
- The cost of the seminar will be €400, (or £340.00 for UK delegates), plus tax. (VAT Delegates who are Personal Members of EABS, or who are employed by a company that is a Corporate Member of the Association, will receive a discount of 10% off the above fees.
- A buffet lunch will be provided during both days of the event, and all delegates are invited to attend the Informal Seminar Dinner as the guests of EABS and Solvay Fluor GmbH on the evening of Tuesday 4th September, 2012.
- Invoices for attendance at the Seminar will be sent by EABS directly to the delegate by e-mail and payment needs to be made on or before 4th August 2012
- Please note that the available places on all the ten previous Seminars were booked very quickly. As a result, and since space is limited to a maximum of 36 delegates, we would strongly recommend that to avoid disappointment you make your booking on the Form that accompanies this Programme, and return it to EABS by fax or e-mail as soon as possible, please!
Please note: Early registration for the Seminar is particularly important for delegates who will require a Visa to enter the countries of the European Union. The issue of a Visa can take up to 10 weeks, and often requires the applicant to present a letter of invitation to the seminar, together with his application for a Visa, to the German Embassy in his country of residence. Delegates who require a formal letter of invitation should indicate this fact, (on the Seminar Registration form, please), so that EABS can arrange for one to be sent to you by Solvay Fluor GmbH.
We look forward to receiving your booking in the very near future.
