Abstract

The present invention provides a kind of methods for enhancing round tube weld strength, this method are as follows: the connector of two round tubes is opposite, the weld seam for welding is formed between two connectors, it is characterized in that, two are respectively opened above with respect to the centrosymmetric strip groove of round tube in the joint of two round tubes along axial direction, and the strip groove on two round tubes is about weld seam bilateral symmetry;One width is equal in the steel plate insertion strip groove of welding round tube diameter, length equal to twice of bar shaped slot length, the weld seam between welding steel and round tube and Conduit Joint.The present invention solves the problems, such as that strength of welded joint is lower than base material, and does not influence the beauty of shape.

Description

A method of enhancing round tube weld strength
Technical field
The present invention relates to welding field more particularly to a kind of methods for enhancing round tube weld strength.
Background technique
Welding technique is exactly under high temperature or condition of high voltage, using welding material (welding rod or welding wire) by two or more than two Base material (workpiece to be welded) connect into the operating method of an entirety.The docking of existing round tube only stamp groove directly into Row welding does not carry out other any processing, is easy to deposit butt weld intensity lower than base material, and when stress is easy to fracture, and exists Certain security risk.
Summary of the invention
In order to eliminate security risk, the present invention provides a kind of method for enhancing round tube weld strength, the technical sides of use Case is as follows:
A method of enhancing round tube weld strength, this method are as follows: the connector of two round tubes is opposite, between two connectors Form the weld seam for welding, which is characterized in that respectively open two above with respect in round tube in the joint of two round tubes along axial direction The symmetrical strip groove of the heart, and the strip groove on two round tubes is about weld seam bilateral symmetry;By a width be equal to welding round tube diameter, In steel plate insertion strip groove of the length equal to twice of bar shaped slot length, the weldering between welding steel and round tube and Conduit Joint Seam.
Further, the steel plate can be with welding round tube same material.
Further, bar shaped slot length is equal to twice of welding round tube diameter.
Further, the steel plate thickness is more than or equal to welding tube wall thickness.
Further, it can also be combined into cross welding fabrication with two blocks of identical steel plates, divided in the butt joint of pipe The corresponding strip groove of cross is not opened;It is welded after cross is inserted into.
The beneficial effects of the present invention are: can solve the problem of strength of welded joint is lower than base material, and do not influence shape Beauty.
Detailed description of the invention
Fig. 1 is that "-" type steel disc welds Conduit Joint front elevation and welding schematic diagram;
Fig. 2 is that cross steel disc welds Conduit Joint front elevation and welding schematic diagram;
Specific embodiment
The invention will be further described With reference to embodiment.
As shown in Figure 1, a kind of method for enhancing round tube weld strength, this method are as follows: the connector of two round tubes is opposite, two The weld seam for welding is formed between a connector, which is characterized in that respectively open two or more in the joint of two round tubes along axial direction About the centrosymmetric strip groove of round tube, and the strip groove on two round tubes is about weld seam bilateral symmetry;One width is equal to weldering It connects in the steel plate insertion strip groove of round tube diameter, length equal to twice of bar shaped slot length, welding steel and round tube and round tube connect Weld seam between head.
After being welded using this kind of method, weld strength enhances 1 times or so.
The steel plate is with welding round tube same material or close to material, such as Q235A and Q235B.Convenient for welding, and weld It is stronger.
Preferably, bar shaped slot length is equal to twice of welding round tube diameter.The steel plate thickness is more than or equal to welding circle The thickness of tube wall.
As shown in Fig. 2, cross welding fabrication can also be combined into two blocks of identical steel plates, divide in the butt joint of pipe The corresponding strip groove of cross is not opened;Butt welding after cross is inserted into.Cross weld strength enhances 2 times.

Claims (5)
