“…An increase in the upset pressure had a similar effect as that of the decrease in the welding currents. As stated by Richardson and Kerstens [23], contact resistance is inversely proportional to the upset pressure. Therefore, enhancement of the upset pressure leads to less heat generation according to Joule's law.…”

Upset resistance dissimilar welding of aluminium and copper narrow rods was performed. Effect of the interface characteristics was studied on the joint mechanical and electrical properties. Upset resistance welding (URW) was successful for production of joints with high strength and electrical conductivity between aluminium and copper rods. Reaction layer at the joint interface was composed of the Al2Cu cellular phase and lamellar eutectic structure of α-Al and Al2Cu. Enhancement of the welding current and decrease in the upset force increased the reaction layer thickness and strength of the joint. URW had no significant detrimental effect on the electrical conductivity of the weld zone. Neither the joint strength nor the joint electrical conductivity was improved by in situ post weld heat treatment.

“…in turn, in articles [16][17] it has shown the use of thermovision tests as a diagnostic tool in the processing of polymer materials, allowing for subsequent modifications and optimization of the injection mould. whereas, in the works [18][19], the authors have presented the use of thermovision analysis to assess the quality of welded joints and to monitor distribution heat during butt welding, while at paper [20] scientists used thermovision tests to assess influence of flash removal parameters on selected properties of friction or resistance welded joints. Therefore, it can be seen that thermovision has found many applications in industry.…”

AnAlysis of ChAnges in the ProPerties of PolymeriC ComPonents Joined by resistAnCe WeldingThe article has been devoted to issues connected with socket fusion welding, which is next to welding one of the methods of thermoplastic polymers joining. in this paper, the research was presented, which the aim was analysis of quality of joints obtained as a result of resistance welding of polypropylene pipes with diameter ø20 in the temperature range of 200÷230°C. To that end a Testo thermal imaging camera was used, flexural strength of the combined components was tested as well as the received weld was observed under a stereoscopic microscope. Conducted studies showed that the best results of joint are obtained during welding at 220°C and 230°C, while lower temperatures did not fully perform their function during the process of joining the pipe elements.
