Inverter Power Sources for Welding and Cutting in Construction
A brief review of innovative technologies and equipment for welding and cutting is presented. Technological and technical-economic aspects of application of this kind of equipment and innovation technologies of metal welding and cutting in construction are considered. The usage of compact inverter electric power sources together with the pulse regime of welding makes it possible to significantly improve the quality of welds, facilitate welding in different spatial positions, welding of details of small thickness and reduce the requirements to the qualification of the welder. The plasma-arc cutting technology makes it possible to significantly increase the thickness of metal components to be cut out. In the process no metal spattering takes place, edges do not need mechanical treatment, any kind of metals and alloys can be cut using just electric power and pressurized air from the conventional compressor.
