Opis:: Artykuł jest wstępem do serii badań, pozwalających dobrać najlepsze parametry napawania metodą GMA stali C45E drutem CastoMag 4554S. Próbki stali zostały przygotowane oraz wstępnie podgrzane do temperatury 300°C. Plan eksperymentu opracowano na podstawie metody Taguchiego. Celem przeprowadzenia optymalizacji był dobór odpowiednich parametrów technologicznych i uzyskanie najmniejszego udziału materiału podłoża w napoinie. Do analizy wyników wykorzystano regresję wielokrotną oraz metodę Taguchiego.
The article is an introduction to a series of investigations that will allow to choose the best parameters of pad welding with GMA method of steel C45E by wire CastoMag 4554S. Steel samples were prepared and preheated to 300 degrees Celsius (C). The plan of experiment was developed on the basis of the Taguchi method. The purpose of the optimization was to select appropriate technological parameters and to obtain the smallest proportion of the substrate material in the padding weld. Analysis of the results was performed using multiple regression and Taguchi method.

Opis:: Resistance spot welding is the most significant joining technique utilized in various industries, like automotive, boilers, vessels, etc., that are commonly subjected to variable tensile-shear forces due to the unsuitable use of the input spot welding variables, which mainly cause the welded joints failure during the service life of the welded assembly. So, in order to avoid such failures, the welding quality of some materials like aluminum must be improved taking into consideration the performance and weight saving of the welded structure. Thus, the need for optimizing the used welding parameters becomes essential for predicting a good welded joint. Accordingly, this study aims at investigating the influence of the spot welding variables, including the squeeze time, welding time, and current on the tensile-shear force of the similar and dissimilar lap joints for aluminum and steel sheets. It was concluded that the use of Taguchi design can improve the welded joints strength through designing the experiments according to the used levels of the input parameters in order to obtain their optimal values that give the optimum tensile-shear force as the response. As a consequence of the present work, the optimal spot welding parameters were successfully obtained.

Opis:: Purpose: The influence of metal active gas welding variables, including current, wire feeding speed and gas flow rate on the ultimate tensile strength and critical buckling load of steel (St.24) and the optimized welding conditions were discussed. Design/methodology/approach: The experimental steps are firstly designing the experiments, secondly conducting the mechanical tests, thirdly analysing the results through Minitab 16 and finally determining the optimum welding parameters. Confirmation tests of the optimized variables were validated. Findings: ANOVA approach manifested that the significant effect of welding variable on the tensile strength was the gas flow rate, while the current was on the critical buckling load. The results are confirmed and given the optimum values. Research limitations/implications: The influence of MAG welding variables (current, wire feeding speed and gas flow rate) on the tensile and buckling strengths of steel will be investigated in order to avoid the failure of many welded assemblies in the structures due to the buckling, in addition to reduce the requirement of long time and high cost to produce such assemblies. Therefore, it is necessary to find a solution to encounter the difficulties in their welding process. Practical implications: The major challenge was how to reduce the time and cost beside gaining the optimum properties through the designed experiments. Originality/value: The results may be helpful to design any welded joints in machine frames, structural steel connections and crane structures at the optimum condition.
