Scientific and technical principles of creating devices for contact welding of biological tissues by DC pulses

According to the results of research work, the conditions for obtaining high-quality compounds in the process of contact welding of biological tissues with electrical pulses are determined. The dependences of the quality indicators of welded joints on the used form of welding pulses, which is characterized by the law of change of current (or power), amplitude and duration, are analyzed.
