method of welding metals bilateral

摘要

1.a bilateral welding metals, in which the periodic pulse current to the welding electrodes are located on opposite sides of the u0441u0432u0430u0440u0438u0432u0430u0435u043cu043eu0433u043e interface and, u043eu0442u043bu0438u0447u0430u044eu0449u0438u0439u0441u00a0 so that, with a view to u043fu043eu0432u044bu0448u0435u043du0438u00a0 stability the quality of welding joints and u0440u0430u0441u0448u0438u0440u0435u043du0438u00a0 technological capabilities, the impulse current to each of the u0441u0432u0430u0440u043e u0447u043du044bu0445 electrodes are alternately.and move them along the interface u043eu0441u0443u0449u0435u0441u0442u0432u043bu00a0u044eu0442 separately.;2. method for u043eu0442u043bu0438u0447u0430u044eu0449u0438u0439u0441u00a0 1, so that the welding electrodes u043eu0441u0443u0449u0435u0441u0442u0432u043bu00a0u044eu0442 in the period of pulse current, and the welding electrodes can cause u0435u043bu044cu043du043e each other by Lu0438, u043eu043fu0440u0435u0434u0435u043bu00a0u0435u043cu0443u044e of u0441u043eu043eu0442u043du043eu0448u0435u043du0438;Lu0438 1.5 v tu0438,;where v is the speed of u043fu0435u0440u0435u043cu0435u0449u0435u043du0438u00a0 electrodes mm / s;;tu0438 - duration of pulse current.;a pulse current is first electrode located in the back.;3. method for u043eu0442u043bu0438u0447u0430u044eu0449u0438u0439u0441u00a0 1, so that, with a view to u0443u0432u0435u043bu0438u0447u0435u043du0438u00a0 depth u043fu0440u043eu043fu043bu0430u0432u043bu0435u043du0438u00a0, movement of welding electrodes u043eu0441u0443u0449u0435u0441u0442u0432u043bu00a0u044eu0442 during a pulse current, and've odes were shifting relative to each other by Lu0438, u043eu043fu0440u0435u0434u0435u043bu00a0u0435u043cu0443u044e of u0441u043eu043eu0442u043du043eu0448u0435u043du0438;Lu0438 0.5 du0441u0432,;where du0441u0432 - diameter of the welding point.;a pulse current is first electrode located in front.
