20.500.12556/RUL-151497 Optimizacija geometrije spoja pri plazemskem spajkanju Optimising joint geometry in plasma brazing Pri že znani geometriji spoja smo optimizirali parametre jakosti varilnega toka in hitrosti dodajnega materiala, da bi izboljšali kakovost spajkanega spoja. Raziskovali smo vpliv novih geometrijskih oblik spajkanih spojev in vpliv tehnoloških parametrov za izdelavo kakovostnega spoja s katerim bi lahko zamenjali obstoječo obliko spoja in dosegli ponovljivo spajkanje v industrijskih pogojih. V okviru raziskave smo spreminjali jakost varilnega toka in hitrost dodajnega materiala. Za izdelavo kakovostnega spajkanega spoja je potrebno upoštevati tudi ostale faktorje in parametre, kot so na primer velikost reže med spajkancema, postavitev spajkancev, oddaljenost gorilnika in mesto dodajanja dodajnega materiala. Optimalni parametri in geometrija omogočajo ponovljive in kakovostne spajkane spoje. Za aktualno obliko spoja smo razvili tehnološke parametre za izdelavo kakovostnih spajkanih spojev, ki omogočajo ustrezno trdnost in obliko zalivanja. Pri optimizaciji geometrije spoja smo dosegli najslabše rezultate z geometrijo spojnega mesta v obliki črke U in najboljše rezultate z obliko vzporednih stranic. With a known joint geometry, the welding current and filler material speed parameters were optimised to improve the quality of the solder joint. We investigated the impact of new solder joint geometries and the influence of technological parameters to produce a quality joint that could replace the actual joint geometry and achieve reproducible soldering under industrial conditions. The welding current intensity and the speed of the filler material were varied during the study. Other factors and parameters, such as the size of the solder gap, the positioning of the solder joints, the distance from the torch and the location of the filler material, must also be considered to produce a quality solder joint. Optimum parameters and geometry allow reproducible and high-quality solder joints. For the current joint design, we have developed the technological parameters to produce quality solder joints that provide the appropriate strength and potting shape. When optimising the joint geometry, the worst results were achieved with a U-shaped joint geometry and the best results with a parallel-sided geometry. plazemsko spajkanje parametrična analiza geometrija spoja jakost varilnega toka hitrost dodajnega materiala plasma brazing parametric analysis joint geometry welding current intensity the speed of adding material true false false [M.
