From practice for practice - that is the basic idea of this collection of terms relating to all aspects of applied welding technology. Therefore, a conscious decision was taken to do without any scientific, academic or too profound expressions. Without any claim to completeness, this collection of 120 terms in ten languages should be a communication basis primarily for the welder but also for all the other people active in welding technology. The classification in subject areas, in addition to the alphabetically sorted lists in the appendix and the supplementary icons, is intended to increase the user friendliness of this pocket translator. The languages are: German, English, French, Russian, Polish, Estonian, Latvian, Lithuanian, Turkish and Arabic.
