Abstract
The invention provides a gas shielding device for a back side for longitudinal joint welding. The gas shielding device is composed of a cross beam, a support, a gas inducing cover and a gas circuit connector; and the support is fixed to the cross beam through bolts, the gas inducing cover is welded to the support, and the gas circuit connector is welded below the gas inducing cover. During longitudinal joint welding, shielding gas flows to the gas inducing cover from the gas circuit connector, the support moves along with the cross beam to achieve gas shielding of the back side for longitudinal joint welding, sufficient gas shielding of the back side for longitudinal joint welding is ensured, the forming effect of a weld joint on the back side is improved, and waste of the shielding gas is reduced.
Description
Technical field
The invention mainly relates to longitudinal seam welding backside gas protection problem, belongs to gas shielded welding technical field.
Background technology
During longitudinal seam welding, in order to realize one side welding with back formation, the back side generally requires gas shield, and existing gas shield device, often heavier, installs inconvenient, and easily causes gas leakage and wastes, and sealing run shaping is poor.
The content of the invention
It is an object of the invention to provide a kind of simple structure, making easy to process, the longitudinal seam welding backside gas protection device for conveniently operating with.
The present invention provide a kind of longitudinal seam welding backside gas protection device by crossbeam, support, drag gas hood, gas path joint to constitute; support is bolted on crossbeam; gas hood is dragged to be welded on support; gas path joint is welded on and drags gas hood lower section; during longitudinal seam welding; protective gas drags gas hood, support together to move with crossbeam by gas path joint flow direction, and to the longitudinal seam welding back side gas shield is carried out.
Using present invention can ensure that the protection of longitudinal seam welding backside gas fully, improves sealing run forming effect, and the waste of reduction protective gas.
Description of the drawings
Accompanying drawing 1 is front view of the invention, and accompanying drawing 2 is top view of the invention, and accompanying drawing 3 is the left view of the present invention, and accompanying drawing 4 is the normal axomometric drawing of the present invention.
In figure：1st, crossbeam, 2, support, 3, drag gas hood,
4th, gas path joint.
Specific embodiment
Such as 1～accompanying drawing of accompanying drawing 4, of the invention to include crossbeam（1）, support（2）, drag gas hood（3）, gas path joint（4）, support（2）It is bolted on crossbeam（1）On, drag gas hood（3）It is welded on support（2）On, gas path joint（4）It is welded on and drags gas hood（3）Lower section, during longitudinal seam welding, protective gas is by gas path joint（4）Flow direction drags gas hood（3）, support（2）With crossbeam（1）Together move, gas shield is carried out to the longitudinal seam welding back side, it is ensured that the protection of longitudinal seam welding backside gas is abundant, improve sealing run forming effect, and reduce the waste of protective gas.
It should be noted that, above example is only to illustrate technical scheme and unrestricted, although being described in detail to the present invention with reference to above-described embodiment, still technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention, all should cover in the middle of scope of the presently claimed invention.
