Abstract

Изобретение относитс к оборудованию дл дуговой сварки неплав щимс электродом и может быть использовано в машиностроении при сварке стыковых соединений тонколистовых конструкций. Цель изобретени - повышение прочности соединений путем увеличени прот женности зоны сплавлени .Устройство содержит корпус 1 , горелки с закрепленным на нем приводом 5 вращени электрода 3. Последний закреплен во втулке 4, установленной на электро- додержателе 5. На электрододержателе 5 эксцентрично закреплен ролик 6, контактирующий с упором 7. Корпус 1 горелки закреплен шарнирно на кронштейне 10. При сварке горелка совершает продольные колебани , привод щие к увеличению прот женности зоны сплавлени и прочности соединений, 5 ил., 1 табл.The invention relates to equipment for arc welding with a non-consumable electrode and can be used in mechanical engineering when welding butt joints of thin-sheet structures. The purpose of the invention is to increase the strength of the joints by increasing the length of the fusion zone. The device includes a housing 1, a burner with a rotating actuator 5 attached to it 3. The latter is fixed in a sleeve 4 mounted on an electric holder 5. A roller 6 is eccentrically fixed on the electrode holder 5, in contact with the stop 7. The burner housing 1 is hinged on the bracket 10. When welding, the burner makes longitudinal vibrations leading to an increase in the length of the fusion zone and the strength of the joints, 5 dl., 1 tab .

Claims

Claim

A device for arc welding, containing a torch with an electrode holder, in which a non-consumable electrode is fixed, a rotation mechanism of the electrode holder with a drive, characterized in that, in order to simplify the design of the device. it is equipped with a mechanism of longitudinal oscillations of the burner, made in the form of a roller mounted eccentrically on the electrode holder, mounted on a stop bracket mounted in contact with the roller, while the burner is mounted on the bracket by means of a ball, and the working end of the non-consumable electrode is located at a distance I from the axis of the joint equal to

I = ε, I = A ε / Β _} where A is the distance from the working end of the non-consumable electrode to the hinge of the burner;

B is the distance from the hinge securing the burner to the transverse axis of the roller;

ε is the eccentricity of the roller relative to the electrode holder.

Type of weld obtained using The ratio of the circumferential speed of rotation of the electrode and welding speed (1) The length of the fusion zone, L, mm The permeability limit of compounds, σ.
