  • Arc Welding In General (AREA)

Abstract

FIELD: marine engineering and other industries. SUBSTANCE: method provides for use of tracking system to check all changes which occur in course of welding. System operates on principle of continuous equalizing of assembly units on balancing devices which are made in form of system of plungers entering each other. EFFECT: improved quality of welded joint.

Claims (2)

1. Устройство для монтажа СМЕ в процессе сварки, включающее корпус, устанавливаемый на технологической опоре и плунжер, отличающееся тем, что устройство снабжено дополнительным плунжером, установленным внутри первого таким образом, что их рабочие полости находятся в противоположных друг другу крайнем нижнем и крайнем верхнем положениях, при этом крайнее верхнее положение занимает рабочая полость внутреннего плунжера, заполняемая сжатым газом с постоянным рассчетным давлением, нижний же объем заполнен гидравлической жидкостью.1. A device for mounting CME in the welding process, comprising a housing mounted on a technological support and a plunger, characterized in that the device is equipped with an additional plunger mounted inside the first so that their working cavities are in opposite extreme lower and upper upper positions while the extreme upper position is occupied by the working cavity of the inner plunger, filled with compressed gas with a constant design pressure, the lower volume is filled with hydraulic fluid. 2. Способ монтажа сборочно-монтажных единиц (СМЕ), включающий установку СМЕ в судовом помещении, стыковку сопрягаемых поверхностей конструкций, крепления к штатной, закрепление прихватками и сварку шва, отличающееся тем, что процесс сварки ведут с одновременным выравниванием СМЕ на балансирующих устройствах типа "плунжер в плунжере", имеющих рабочую полость, при этом рабочую полость заполняют газом с давлением, определяемым из соотношения:

Figure 00000002

где qж - удельное давление гидравлической среды.2. The method of mounting assembly units (CME), including the installation of CME in the ship's premises, docking of mating surfaces of structures, fastening to the standard, fixing with tacks and welding of the seam, characterized in that the welding process is carried out with the simultaneous alignment of CME on balancing devices of the type " a plunger in a plunger "having a working cavity, while the working cavity is filled with gas with a pressure determined from the ratio:
Figure 00000001

where D is the diameter of the 1st plunger;
d 1 - the diameter of the 2nd plunger;
d 2 - the diameter of the rod of the 2nd plunger;
q 2 is the pressure of the compressed gas in the upper cavity of the device;
n is the number of devices used;
G is the mass of CME, selected from the ratio;
K - coefficient of friction of the plunger against the plunger
Figure 00000002

where q W is the specific pressure of the hydraulic medium.
