Löt 2022 - Honored with the Erich Lugscheider Award


The “Löt 2022” came to an end on June 23. For 3 days, participants learned about current research results and technical innovations in brazing, high-temperature brazing and diffusion bonding.

During this conference, I was awarded the Erich-Lugscheider-Award, for which I would like to take this opportunity to thank the jury. I consider it a great honor to be one of the recipients of this award, which is only presented every three years.


Online brazing seminar


My next online brazing seminar (english version) takes place on March, 23rd and 24th. It covers the following topics:

  • Basics of brazing technology
  • Brazing process
  • Brazing alloys and fluxes
  • Design of brazed joints
  • Imperfections of brazed joints and their testing

The SCHMOOR brazing online brazing seminar


In addition to the classic on-site seminar, I now also offer an online brazing seminar. The aim of the seminar is to convey the basic knowledge of brazing technology for the professional design of brazing processes, brazing alloys, fluxes and process parameters to be used.

The online seminar is offered as a 1:1 training for individuals or for small groups of a maximum of 4 participants. It comprises 10 modules, which deal with the basic knowledge as well as the discussion of brazing topics of the participants.

The dates for the modules are arranged individually and can therefore be integrated into the daily work routine without time-consuming travel.

For detailed information about the seminar, please use this link or contact me by mail ( or phone (+49 6021 4556778).

Conferences and Seminars 2021


Subject to further restrictions due to the corona pandemic, the following international conferences on brazing are planned for this year:

In Germany two seminars on brazing are planned. Those can be recommended to your German speaking colleagues.

I would also like to draw your attention to the world's leading welding and cutting trade fair in Essen, Germany from 13th to 17th of September 2021, where brazing manufacturers as well as manufacturers of brazing systems will be represented.

More information are available on the respective Websites. I would be happy to meet interested participants at some of these events.

Handbook of Inductive Soldering


The "Handbuch Induktives Löten" edited by Mr. Hans-Joachim Peter is now also available in an English version titled “Handbook of Inductive Soldering”.

The handbook deals with inductive brazing in great detail and contains a good introduction to brazing technology.

The book is highly recommended for both beginners and experienced users.


Brazing consultancy by Schmoor brazing


Optimisation of existing brazing processes, definition of new brazing processes, damage analysis and definition of remedial measures, selection of brazing alloys and fluxes, design suitable for brazing, assessment of brazed joints, seminar lectures - the brazing topics and associated applications worked on by Schmoor brazing were and are manifold and technically always of high interest to me.

Whether flame brazing, induction brazing, resistance brazing or furnace brazing under inert gas or in vacuum - each topic had and has its own challenges and is successfully dealt with according to customer requirements.

The required brazing consultation is always customer-oriented and flexible in terms of time, from one-off consultation to project work with a defined timeframe to continuous consultation over several months or even years.

It is a personal concern of mine to continue to provide my customers with professional and economically sound advice on the subject of brazing.


Löt 2019


From 21st to 23rd of May the Löt 2019  takes place again in Aachen, Germany.

I would appreciate very much to meet interested participants during the conference. See you in Aachen.

New address


After 2 years of technical consulting on brazing my office moved to Blumenstraße 24, 63743 Aschaffenburg. By this also my phone number changed to +49 6021 4556 778


Conferences and Seminars 2018


This year several international conferences on brazing are organized. Among others are:

In Germany two seminars are organized on brazing. Those can be recommended to your German speaking colleagues.

More information are available on the respective Websites. I would be happy to meet interested participants during the conferences or at the seminar in Ostfildern.

New standards for brazing


Beginning of this year two standards for brazing have been published in their revised versions. Both standards are international ones and deal with the designation respectively composition of brazing filler metals:

  • ISO 3677 Filler metal for soldering and brazing – Designation
  • ISO 17672 Brazing – Filler metals

ISO 3677 specifies designations for filler materials for soldering and brazing, does however not specify their compositions. The main modification compared to the previous version is the deletion of the term “braze welding” and the respective chapter of related filler metals.

ISO 17672 specifies the compositional ranges of a series of filler metals used for brazing. The filler metals are divided into seven classes, related to their composition, but not necessarily to the major element present:

  • Aluminium and magnesium brazing filler metals
  • Silver brazing filler metals
  • Copper-phosphorus brazing filler metals
  • Copper brazing filler metals
  • Nickel (and cobalt) brazing filler metals
  • Palladium bearing brazing filler metals
  • Gold bearing brazing filler metals

Furthermore impurity limits for special vacuum requirements and technical delivery conditions are specified.

The key focus is on brazing technology-related consultancy services and process management for companies operating within the refrigeration/air-conditioning technology, tooling and electrical industries, as well as industrial technology and automotive. The newly established company with headquarters in the city of Aschaffenburg operates independently of system and brazing suppliers. Schmoor brazing firmly believes that consultation and results should not only focus on technical aspects but must also pay attention to economic factors.

“I am always willing to supervise the practical implementation of my recommendations. This is a question of responsibility for me” says Hartmut Schmoor, proprietor of Schmoor brazing. The combination of consultation, implementation, monitoring and training aims to service customer requests from one source. Whether it is the development of new methods, the optimisation of existing processes or product quality, the reduction of costs or production times, Schmoor places great value on working independently of system and brazing suppliers. Only then is it possible to develop the best solution for the customer from a technical and economic standpoint.

Schmoor places a strong emphasis on sharing very specialised knowledge within the discipline of brazing technology, and expanding brazing expertise within companies.
