Embodiment Construction

[0037] Such as Figure 1-2 As shown, an auxiliary welding device includes a main body mechanism 4 , a cover body 6 , a movable cover plate 9 , a workpiece support 5 , an air inlet pipe 1 , and a gas distribution pipe 2 . The main mechanism 4 is a cavity structure, the main mechanism 4 includes an air inlet and a storage port, and the protective gas is passed into the cavity from the air inlet, and the processing part is arranged at the storage opening; On the opposite face, the air inlet pipe 1 extends into the cavity through the air inlet, and the outer wall of the air inlet pipe 1 is fixed on the inner wall of the air inlet. The cover body 6 is covered on the storage port, and the cover body 6 is provided with a hole 12 for welding, and the welding torch 8 and welding wire 7 for welding are stretched into the hole 12 for welding and can also be used at the hole 12 for welding. The internal parts to be processed can be welded.

[0038] The main mechanism 4 is cylindrical, t...

Abstract

The invention discloses an auxiliary welding device and a use method. The device comprises a main mechanism, the main mechanism is of a cavity structure, the main mechanism comprises an air inlet and an object containing opening, protection gas is led into the cavity from the air inlet, a to-be-machined part is arranged at the position of the object containing opening, the device further comprises a cover covering the object containing opening, a welding gun used for welding and a welding hole enabling a welding wire to stretch in and capable of implementing the welding process is formed in the cover, and the device has the beneficial effects that machining is carried out in protection gas which cannot affect the welding effect and can protect the to-be-machined part, due to arrangement of the cover, the gas amount led into the air inlet can be reduced, the contact area of the welding position of the external air and the to-be-machined part and the welding position is avoided, and the welding hole is arranged and ensures that welding is carried out while the protection gas is led.

Description

technical field [0001] The invention relates to the field of welding processing in the mechanical industry, in particular to an auxiliary welding device and a use method. Background technique [0002] In the field of welding, the parts to be welded or the materials used for welding react in the air under the action of the high temperature generated during the welding process, thereby affecting the parts to be welded or the welding place. [0003] For example, zirconium has great activity at high temperature and can react with many gases. Air (among which oxygen is the most serious) reacts with zirconium to form brittle compounds, which sharply reduces the mechanical properties and corrosion resistance of welds. In order to prevent the external gas from affecting the welding effect and the parts to be welded at high temperature, a device is urgently needed to assist welding, so as to protect the parts to be welded and ensure the quality of the weld.
