Claims (2)

1. Способ контактно-стыковой сварки трубы с заглушкой, включающий фиксацию конца трубы с заглублением в сварочной оснастке, разогрев сварочным током сжатых торцами конца трубы и заглушки, имеющей участок, ввариваемый в стенку трубы, диаметром больше внутреннего, но меньше наружного диаметра трубы и последующую вварку заглушки в стенку трубы с переменной скоростью продвижения заглушки, отличающийся тем, что участок трубы от ее конца на длину 1,5-3 толщины стенки трубы размещают на участке сварочной оснастки, обладающем электрическим сопротивлением меньше сопротивления материала участка трубы в зоне сварки, с последующим преимущественным разогревом концов участка трубы за счет контактного сопротивления в стыке между торцом трубы и заглушки и местом преимущественной подачи сварочного тока в трубу, расположенном на расстоянии, равном 1,5-3 толщины стенки трубы от ее конца.1. The method of contact-butt welding of a pipe with a plug, including fixing the pipe end with deepening in the welding tool, heating the welding end with a pipe end end and a plug having a section welded into the pipe wall with a diameter larger than the inner but smaller than the outer diameter of the pipe and the subsequent welding the plug into the pipe wall with a variable speed of advancement of the plug, characterized in that the pipe section from its end to a length of 1.5-3 pipe wall thicknesses is placed on the welding equipment section having electrical resistance the phenomenon is less than the resistance of the material of the pipe section in the welding zone, with the subsequent preferential heating of the ends of the pipe section due to contact resistance in the junction between the end of the pipe and the plug and the place of the predominant supply of welding current to the pipe, located at a distance equal to 1.5-3 pipe wall thickness from its end. 2. Способ по п.1, отличающийся тем, что разогрев свариваемых деталей при сварке ведут до образования общей по длине сварного соединения зоны термического влияния, ширина которой в центральной части сварного соединения равна 0,1-3 толщины стенки трубы.2. The method according to claim 1, characterized in that the heating of the parts to be welded during welding is carried out until a zone of thermal influence is formed along the length of the welded joint, the width of which in the central part of the welded joint is 0.1-3 the thickness of the pipe wall.
