Welding and methodology of scientific research. Laboratory workshop. Tutorial

The training manual provides laboratory work on welding on small currents with non-fluid and melting electrodes when powering an arc from a single-phase rectifier with a condenser multiplier of voltage, consuming 1.5-2 times less energy compared to traditional and no more than inverting, plasma-powder Sellating with plasmoron with without oscillator ignition of a plasma arc.
The ignition of an arc on currents 1-15 and non-fluid and melting electrodes and the features of burning a three-phase arc with melting electrodes are considered.
Designed for students of the training on 03/15/01 "Mechanical Engineering" in the study of disciplines "Methodology of scientific research", "Technological foundations of welding with melting and pressure", "new methods of welding"
