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.
