Abstract
Способ сварки трением, при котором одну из свариваемых заготовок приводят во вращение и прикладывают к ним давление нагрева разное по величине на этой стадии, а затем давление проковки, отличающийся тем, что стадию нагрева разбивают на три периода начальный, основной и окончательный, причем при начальном нагреве удаляют оксидные пленки и загрязнения со стыкуемых поверхностей и заканчивают период начального нагрева снижением давления до величины давления основного нагрева, которое составляет 25…50% от давления начального нагрева и выполняют основной нагрев до температуры сварки в стыке, после чего в период окончательного нагрева отключают привод вращения заготовки и увеличивают давление основного нагрева до давления проковки, при этом длительность нарастания давления меньше или равна длительности прекращения вращения заготовки.A method of friction welding, in which one of the parts to be welded is brought into rotation and a heating pressure of different magnitude is applied to them at this stage, and then the forging pressure, characterized in that the heating stage is divided into three periods, initial, main and final, and at the initial heating remove oxide films and contaminants from abutting surfaces and end the initial heating period by reducing the pressure to a pressure value of the main heating, which is 25 ... 50% of the initial heating pressure and the main heating is heated up to the welding temperature at the butt, after which during the final heating the drive for turning the workpiece is turned off and the pressure of the main heating is increased to the forging pressure, while the duration of the pressure rise is less than or equal to the duration of the cessation of rotation of the workpiece.
