TWI755089B - Recyclable back-lining for welding - Google Patents

Abstract

The present invention relates to a recyclable back-lining for welding which is made of carbon material. The characteristic of the present invention is that the carbon material accounts for over 60% of the overall weight of the back-lining and the carbon material can stand a high temperature of 1500℃ and above. Furthermore, after the welding work is completed, the back-lining can be used as a recarburizing agent in metal smelting or one of the raw materials for producing new bed liners, making the back-lining for welding no longer a consumable item for one-time use.

Description

Recyclable Welding Backing

The present invention relates to a backing; more particularly, to a recyclable welding backing.

Generally, the backing used in the welding operation is made of ceramics, so after the welding operation is completed, it is directly discarded as waste and cannot be recycled. In addition, the strength of the solder joint after welding depends entirely on the operator. Therefore, if the backing can be recycled after use, it will be far superior to the ceramic backing in terms of environmental protection and practicability.

In view of this, the applicant of this case, based on his years of experience in research and development in related fields, conducted in-depth discussions on the aforementioned deficiencies, and actively sought solutions based on the aforementioned needs. invention.

The main object of the present invention is to provide a backing which can recycle the backing after welding.

In order to achieve the above-mentioned purpose, the recyclable welding backing of the present invention is made of carbon-based materials, characterized in that the carbon-based materials account for more than 60% of the overall weight of the backing, and the carbon-based materials The material can withstand high temperature above 1500 ℃, in addition, the backing is recycled as a recarburizer for smelting metal after welding.

The advantage of the recyclable backing for welding of the present invention is that the present invention can be used as a recarburizer after welding is completed, so that the backing for welding is no longer just a disposable consumable in use.

In order to allow a more detailed understanding of the purpose, effect, features and structure of the present invention, preferred embodiments are given and described in conjunction with the drawings as follows.

First, please refer to FIG. 1 . FIG. 1 is a schematic diagram (1) of the recyclable welding backing according to the present invention.

The recyclable welding backing 1 of the present invention is made of carbon-based materials, and is characterized in that the carbon-based materials account for more than 60% of the overall weight of the backing, and the carbon-based materials can withstand High temperature above 1500 ℃, in addition, the carbon material is made of non-biological carbon or biological carbon, and the backing can be used as a recarburizer for smelting metal after welding, or as a new backing one of the raw materials.

In addition, the present invention adopts the method of adding an adhesive or calcining to fix and shape the carbonaceous material, and the method of adding an adhesive to fix and shape the carbonaceous material is relatively simple in manufacture.

In addition, the cross-section of the present invention can be designed to be arc or U-shaped as shown in Figures 1 and 2, and the backing of this shape is suitable for welding round rod-shaped materials. In addition, the cross-section of the present invention can also be designed as The flat plate as shown in Figure 3 or the flat plate with grooves as shown in Figure 4 and Figure 5, and the backing of this shape is suitable for the welding of flat materials.

In order to allow a more detailed understanding of the purpose, effect, features and structure of the present invention, preferred embodiments are given and described in conjunction with the drawings as follows.

Please refer to FIG. 6 and FIG. 7. FIG. 6 is a schematic diagram (1) of the implementation of the recyclable welding backing of the present invention, and FIG. 7 is a schematic diagram (2) of the implementation of the recyclable welding backing of the present invention.

As shown in FIG. 6 , when two steel bars 2 are to be welded together, it is the best choice to use an arc-shaped or U-shaped recyclable welding backing 1 of the present invention, and then place the present invention on the two steel bars 2 The welding operation can be started after the back of the gap between the steel bars. During welding, the high-temperature solder will first accumulate on the invention, and gradually fill the gap between the steel bars 2. During the welding process, the high temperature of the solder will cause The carbon in the carbon will be taken out by the high temperature, and at the same time, the carbon will be melted into the high temperature solder to form carburization and help to improve the strength of the solder joint.

Next, as shown in FIG. 7 , when two steel plates 3 are to be welded together, it is the best choice to use the recyclable welding backing 1 of the present invention in the form of a flat plate, and then the present invention is placed between the two steel plates 3 The welding operation can be started after the back of the gap between the two parts. At the beginning of the welding operation, when the high-temperature solder touches the present invention, the high temperature of the solder will cause the carbon in the carbon to be brought out by the high temperature, and at the same time let the carbon melt into the high temperature. In the solder, carburization is formed and helps to improve the strength of the solder joint.

Finally, when the welding operation is over, the used invention has two processing methods, one of which is to directly send it to a metal smelting field, and put the used invention into a smelting furnace to use as a recarburizer for smelting metal, Another is to use the used invention as one of the raw materials for making new backings.

To sum up the above, the main feature of the recyclable welding backing of the present invention is that the present invention can be used as a recarburizer after welding, so that the welding backing is no longer just a disposable consumable in use.
