Popis: | The control method of the initial arc ignition in the gas-shielded welding is offered. It is based on the short-circuit current limitation after heating the wire stick-out with the metal passing current to the plastic state for the time of the wire burnout approach point at the stick-out-to-work distance not exceeding the arc breaking length. The dependences describing the conditions necessary and sufficient for the reliable establishment of the welding process after the first wire-work contact are experimentally investigated and analytically determined. |
