First, it was necessary to familiarise oneself with a welding method designated as 141 according to a norm ČSN EN ISO 4063 as well as with technological features of iron aluminides. Based on this knowledge we had to prepare a device for heating and regulation up to 400 degrees Centigrade. We created an entirely new workplace which met our requirements for the speed and mentioned preheating. The welding process of the test samples was monitored by Weld Monitor system which recorded current, voltage and gas flow. The speed of welding was observed on a display of a frequency inverter (no sensor for detecting the speed was connected to the computer). We investigated the weldability of aluminide and the effect of varied parameters on the quality of the welded joint. We aimed to create welded joints without defects on various thicknesses of the tested material and prepare reference material for other tests. We tried to make parameters for many thicknesses of the material. We observed the effect of the parameters on the geometry of the welded joint bath and the integrity of the welded joint. The welded joints were assessed visually and measured by a penetration test.
