Abstract
The paper gives the results of experiments on qualitative assessment of the influence of thermomechanical treatment on the strength of spot welded joint. Rationality of shock application of the compressive force at the temperature close to the recrystallisation point of the metal being welded is shown.
 
 
Keywords: resistance spot welding, welded joint, thermomechanical treatment, shock application of compressive force, crystalline structure refinement, mechanical strength
