Description
Известные способы сварки труб из двух полуцилиндрических заготовок путем пагрева свариваемых кромок пропускапием тока высокой частоты в продольном направлении и последующего обжати заготовок недостаточно производительны.Known methods of welding pipes from two semi-cylindrical billets by penetrating the welded edges by passing the high-frequency current in the longitudinal direction and subsequent crimping of the blanks are not sufficiently productive.
В описываемом способе этот недостаток устранен тем, что нагрев свариваемых кромок и их обжатие производ т сразу по всей длине.In the described method, this disadvantage is eliminated by the fact that the welded edges are heated and their compression is performed along the entire length.
Иа чертеже показана схема, по сн юща описываемый способ сварки труб.The drawing shows a diagram explaining the described method of pipe welding.
Заготовки дл труб 1 выполн ютс полуцилиндрической формы в соответствии с внутренним диаметром трубы и устанавливаютс кромками, параллельно друг другу с зазором 2.The billets for pipes 1 are made in a semi-cylindrical shape in accordance with the internal diameter of the pipe and are set with edges parallel to each other with a gap 2.
Передние концы труб соедин ютс с генератором высокой частоты 3, а задние концы - между собой контактами 4.The front ends of the tubes are connected to the high frequency generator 3, and the rear ends to each other by the contacts 4.
По половинкам трубы пропускаетс ток высокой частоты таким образом , что по одной половинке ток протекает в любой момент в одном направлении , а по другой половинке- в противоположном направлении.A high-frequency current is passed through the halves of the pipe in such a way that the current flows through one half at any moment in one direction, and through the other half in the opposite direction.
Кромки в течение нескольких секунд довод тс до оплавлени (сварочна температура), ,а затем производитс обжим заготовок, и происходит сварка их по всей длипе.The edges are reflowed for a few seconds (welding temperature), and then the blanks are crimped, and they are welded along the entire length.
Предмет изобретени Subject invention
Способ сварки труб из двух полуцилиндрических заготовок путем нагрева свариваемых кромок пропусканием тока высокой частоты в продольном , направлении и последующего обжати заготовок, отличающийс тем, что, с целью повышени производительности, нагрев свариваемых кромок и их обжатие производ т сразу по всей длине.The method of welding pipes from two semi-cylindrical blanks by heating the edges to be welded by passing a high-frequency current in the longitudinal, direction and subsequent crimping of the blanks, characterized in that, in order to increase productivity, the edges to be welded and crimped are produced along the entire length.
