Abstract
The invention discloses a welding method for a copper pipe liquid accumulator. According to the welding method for the copper pipe liquid accumulator, an internally-inserted guide pipe connected with the liquid accumulator is provided with an oblique cut opening and welding depth marks; the flame of a welding gun for welding is a neutral flame; and after welding is completed, transferring can be conducted only after welding spots are completely cooled. The welding cost is low, and the efficiency is high.
Description
Technical field
The present invention relates to Welding Structure and the welding method of copper reservoir, particularly belong to a kind of copper pipe reservoir welding method.
Background technology
Vaporizer reservoir is one of vitals in refrigeration plant, is widely used to store the highly pressurised liquid of condenser, does not cause liquid to flood condenser surface.Reservoir can make the heat transfer area of condenser play one's part to the full, and regulates and stablize the circulation of cold-producing medium for adaptation condition variation.He may also operate as the effect of fluid-tight, prevents higher pressure refrigerant gas from channeling in low-pressure system pipeline.So welding procedure and welding method for reservoir require higher.
Summary of the invention
It is an object of the invention to provide a kind of copper pipe reservoir welding method, by interpolation pipe being opened the angular cut of 45 ° and portraying depth of weld labelling, made the solder yield of copper pipe reservoir be improved.
The technical solution used in the present invention is as follows:
A kind of copper pipe reservoir welding method, it possesses: the interpolation conduit being connected with reservoir has angular cut and two depth of weld labellings；Welding torch flame is neutral flame；Have to wait for solder joint after having welded to cool down can carry completely.
The angular cut of described interpolation conduit is 45 °, depth of weld A marking path port 15mm, depth of weld B marking path port 20mm.
Described welding gun is neutral flame at welding process Flame always.
Described welding complete after cool time, it is necessary to wait solder joint cool down completely >=15S after can carry or carry out other operation.
Compared with the prior art, beneficial effects of the present invention is as follows:
Welding cost of the present invention is low, and effect is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Seeing accompanying drawing, a kind of copper pipe reservoir welding method, the interpolation conduit 1 being connected with reservoir 4 has angular cut and two depth of weld labellings 2 and 3；Welding torch flame is neutral flame；Have to wait for solder joint after having welded to cool down can carry completely.The angular cut of described interpolation conduit is 45 °, and depth of weld A labelling 2 is apart from port 15mm, and depth of weld B labelling 3 is apart from port 20mm.Described welding gun is neutral flame at welding process Flame always.Described welding complete after cool time, it is necessary to wait solder joint cool down completely >=15S after can carry or carry out other operation.Before welding, check that reservoir and interpolation conduit are the most qualified, interpolation conduit angle end is inserted reservoir, until reservoir port is concordant with depth of weld labelling A, vertical position welding as far as possible during welding, after having welded, it is necessary to can carry after solder joint cools down (>=15S) completely or carry out other operation, in order to avoid because carrying causes the defects such as solder joint fracture, micro-crack.Whether check the size between B labelling and the reservoir mouth of pipe equal to the distance between A, B labelling after welding, if equal, then interpolation tube insertion depth reaches requirement.
