Claims (2)

1. Способ изготовления длинномерных изделий различного профиля, включающий изготовление обечаек из листового материала сваркой продольных швов, их торцовку, стыковку кромок обечаек на центраторе и сварку их кольцевых швов в атмосфере защитного газа, отличающийся тем, что перед изготовлением обечаек осуществляют нарезку заданного количества заготовок из листового материала в пакете с получением в нем заготовок, равных по длине и ширине, торцовку изготовленных из них обечаек производят одновременно с двух сторон, а сварку кольцевых швов проводят с постоянным поддувом защитного газа, подаваемого с внутренней стороны изделия на свариваемые кромки обечаек.1. A method of manufacturing long products of various profiles, including the manufacture of shells from sheet material by welding longitudinal seams, their trimming, joining the edges of the shells on the centralizer and welding of their circumferential seams in a protective gas atmosphere, characterized in that before the manufacture of shells, a predetermined number of blanks is cut from sheet material in a package with obtaining blanks equal in length and width therein, trimming of shells made from them is carried out simultaneously on both sides, and welding of ring joints carried out with constant blowing of the protective gas supplied from the inside of the product to the welded edges of the shells. 2. Устройство для изготовления длинномерных изделий различного профиля, включающее расположенную внутри изделия направляющую с установленным на ней центратором, отличающееся тем, что направляющая выполнена в виде штанги с гладкой поверхностью и равного диаметра по всей длине, которая снабжена вкладышем со ступенчатыми упорно-центрирующими поверхностями, расположенным в ее торцевой части, а центратор, выполненный в виде секторного разжимного приспособления, установлен подвижно на гладкой поверхности штанги и снабжен каналом для подачи защитного газа в корень шва свариваемых кромок. 2. A device for the manufacture of long products of various profiles, including a guide located inside the product with a centralizer installed on it, characterized in that the guide is made in the form of a rod with a smooth surface and equal diameter over the entire length, which is equipped with an insert with stepped stop-centering surfaces, located in its end part, and the centralizer, made in the form of a sector expansion device, is mounted movably on a smooth surface of the rod and is equipped with a feed channel and shielding gas at the root of the seam of the welded edges.
