Source: presentation „Forge Welding“ by Stefan GriwenkaĪn impression of the historical development of welding technology is given by the following, however without being completeness, chronology: Both parts were heated by the fire and additionally connected by means of an external force. At that time connecting two metallic pieces has been accomplished by forge welding.
1.2įrom the Sumerians to the Laser In the beginning there was fire! For many years and this goes back some 6000 years ago, even for welding technology this was only applicable original energy source. Besides welding, brazing (chapter 1.16), bonding (chapter 1.18), mechanical joining and cutting plays an important role in industrial application. General introduction into the welding technology What is welding technology?ĭescription: Welding technology Welding Technology is the sum of knowledge and experience regarding the application of weld technical processes which has been acquired and compiled by experts during many years. Welding technology comes across to us in many ways without directly being noticed.įigure 1: Welding Technology “wherever you look“ (Bild: DVS - Deutscher Verband für Schweißen und verwandte Verfahren e. This way of thinking goes from dental braces to bicycles, balcony fences to porch roofs, as well as from automobiles, ships, air planes up to bridges houses and skyscrapers. They assume that the product will safely comply with the defined functions. For the users of welded products welding technology is basically of less importance. It is being found in almost every aspect of our life and its aim is to join separate elements of a construction or product which simply cannot be manufactured by just one piece. Welding is a type of joining that cannot be taken out from today’s world. International Welding Engineer / Technologist (DVS / EWF / IIW ).
