Abstract

The utility model relates to an argon filling device for a pipe argon arc welder in the filed of gas shield welding technique consisting of a welded pipe, a plug, a grip nut, a baffle, a sealing strip, an internal screw sleeve, a hole, a duct and an external screw coupler. One end of the duct has an external screw thread screwed by a grip nut, inserted by a baffle, a sealing strip and again a baffle. The internal screw sleeve with holes is screwed into the external screw thread of the duct tightly against the baffle, the external screw coupler is screwed into the other end of the internal screw sleeve, inserted by a baffle, a sealing strip and again a baffle fastened by the grip nut. The plug is screwed into an internal hole on one end of the external external screw coupler, the hole is inflated after being in alignment with the crater, the gas comes out from the hole directly into the crater with litter scattering, thereby protecting the crater and reducing the inflating space. The workpieces is easy in alignment and the utility model is applicable for mass rotary welding of pipes with various apertures and lengths while saving gas and tool material.

Description

Tube Argon Arc Welding Argon-filling Device

Affiliated technical field

The utility model relates to a kind of Tube Argon Arc Welding Argon-filling Device, carries out argon-filled protection to managing inside specifically in the pipe gas shielded arc welding, belongs to the gas shielded arc welding technical field.

Background technology

At present; known gas shielded arc welding is to carry out gas protection welding on the welded part surface; all carry out applying argon gas in the commute oxidation tube during pipe welding; the protection effect is undesirable; the argon gas waste is serious, and especially to big caliber welding and welding in batches, not only the argon gas waste is serious; and the frock making complexity, be difficult to guarantee welding quality.

Summary of the invention

In order to overcome above-mentioned technical deficiency, the utility model provides a kind of Tube Argon Arc Welding Argon-filling Device, and this Tube Argon Arc Welding Argon-filling Device can not only weld on general plumber's part, can also be in caliber welding and welding, rotating welding greatly in batches.

The technical scheme that its technical problem that solves the utility model adopts is: it is by welded pipe, plug, binding nut, catch, diaphragm seal, the internal thread sleeve pipe, the hole, conduit, male connector is formed, one end of conduit is shaped on external screw thread, on external screw thread, be screwed into binding nut, be inserted in catch, diaphragm seal, catch, be drilled with the hole on the internal thread sleeve pipe, the internal thread sleeve pipe is screwed on the external screw thread of conduit and is close to catch, male connector is screwed into the other end of internal thread sleeve pipe, be inserted in catch successively, diaphragm seal, catch, fastening by binding nut, plug is screwed into the endoporus of male connector one end; Insert in the welded pipe combination back, after the hole aligns weld bond, and inflation, gas is gone out direct protection weld bond by the hole.

The beneficial effects of the utility model are: reduced plenum space, made gas directly arrive weld bond, gas dissipation is few, protects effectively, and workpiece aligns easily, is fit in batches, rotating welding, saves gas, frock material, is applicable to the pipe welding of various apertures, length.
