[0002] Intergranular corrosion is a type of local corrosion, which is corrosion that extends inward along the interface between metal grains. It is mainly due to the difference in chemical composition between the surface and the interior of the grains and the presence of impurities or internal stress at the grain boundaries. Intergranular corrosion destroys the bonding between grains and greatly reduces the mechanical strength of the metal. Moreover, after the corrosion occurs, the surface of the metal and alloy still maintains a certain metallic luster and no signs of damage can be seen, but the bonding force between the grains is significantly weakened, the mechanical properties deteriorate, and it cannot withstand knocking, so it is a very dangerous corrosion. It usually occurs in brass, hard aluminum alloys and some stainless steels and nickel-based alloys. Intergranular corrosion of stainless steel welds is a major problem in the chemical industry.

[0003] Generally, the instantaneous heat in the welding process is too high, which affects the internal structure of the weld, especially stainless steel parts. Excessive heat output during welding can easily cause intergranular corrosion in the heat-affected zone of the weld. Excavator exhaust pipes vibrate frequently, which can easily lead to quality problems such as weld cracking. This not only poses a safety hazard, but also causes economic losses.

[0004] The method of dealing with intergranular corrosion can control the residence time in the dangerous temperature zone to prevent overheating, and weld and cool quickly so that carbon does not have time to precipitate.

[0033] The embodiments of the present invention are as follows:

[0034] The stainless steel welded water circulation heat dissipation jacket comprises a water supply device, a water delivery device and a cooling device. The water supply device and the cooling device are connected through the water delivery device. The cooling water is provided by the water supply device, and the cooling water is delivered to the cooling device through the water delivery device. Then, the cooling device is used to uniformly and quickly dissipate the heat of the exhaust pipe fittings. Compared with the traditional method of placing the pipe fittings in a water tank for cooling, it can prevent structural problems caused by direct contact with water and rapid cooling.

[0035] The cooling device includes a cooling copper sleeve 12, which includes two completely identical semi-cylinders. The two semi-cylinders can form a cylinder after being combined. The diameter of the cylinder is slightly smaller than the diameter of the exhaust pipe fitting, which is convenient for placing the cooling copper sleeve 12 into the exhaust pipe fitting. A water channel is provided inside the semi-cylinder. The water channel can be set in two forms, either a spiral structure or a maze structure, to improve the cooling effect.

[0036] A semi-cylindrical groove coaxial with the semi-cylinder is arranged on the rectangular surface of the semi-cylinder, and the two grooves can be connected to form a cylindrical surface coaxial with the semi-cylinder.

[0037] The cooling device also includes a top plate 8, which is provided with four through holes 6. The water passage at the upper end of the cooling copper sleeve 12 is connected to a connecting pipe 7. The diameter of the through hole 6 is larger than the diameter of the connecting pipe 7. The thickness of the top plate 8 is slightly larger than the length of the connecting pipe 7. The upper end of the connecting pipe 7 is connected to a water head 5.

[0038] Since the diameter of the connecting pipe 7 is smaller than the diameter of the through hole 6 , the connecting pipe 7 can move in the through hole 6 , thereby enabling the two cooling copper sleeves 12 to move relative to each other.

[0039] The lower end of the water head 5 is provided with a protruding edge, and the diameter of the protruding edge is larger than the diameter of the through hole 6, so that the top plate 8 will not be separated from the connecting pipe 7. The water head 5 on a semi-cylinder is respectively connected to the water inlet pipe 2 and the water inlet pipe 2. The cool cooling water enters from the water inlet pipe 2, absorbs the temperature of the exhaust pipe after passing through the cooling copper sleeve 12, and is discharged from the return pipe 3 after the water is heated, completing the cooling process.

[0040] In order to better ensure the contact between the cooling copper sleeve 12 and the exhaust pipe fitting, a base 9 is provided. A tensioning column 10 coaxial with the base 9 is provided at the upper end of the base 9. The tensioning column 10 is a truncated cone structure with a thin upper end and a thick lower end. When the two semi-cylinders are combined, the diameter of the cylindrical surface is between the diameter of the upper end and the diameter of the lower end of the tensioning column 10. When the cooling copper sleeve 12 is placed on the base 9, the two semi-cylinders will be stretched open by the tensioning column 10, so that the outer side surface of the semi-cylinder fits the exhaust pipe fitting, making the cooling copper sleeve 12 and the exhaust pipe fitting in closer contact, thereby improving the heat transfer efficiency, improving the cooling effect, and shortening the cooling time.

[0041] The tensioning column 10 is a two-section structure including an upper section and a lower section, wherein the upper section is a truncated cone structure and the lower section is a cylindrical structure.

[0042] A plurality of limit blocks 11 are also provided on the upper part of the base 9. The limit blocks 11 are located on the same circle, which is concentric with the base 9. At the same time, the inner diameter of the circle is equal to the diameter of the exhaust pipe. After the cooling copper sleeve 12 is opened, its outer diameter is the same as the inner diameter of the cooling copper sleeve 12.

[0043] The water inlet pipe 2 and the water return pipe 3 are soft rubber pipes, which will not affect the relative movement of the semi-cylinder. The water pump 4 is connected to the middle of the water inlet pipe 2. The water supply device includes a water tank 1. The open ends of the water inlet pipe 2 are connected to the lower end of the water tank 1, and the open ends of the water return pipe 3 are connected to the water tank 1. The cooling water is driven to circulate in the entire system through the water pump 4.

[0044] In a further embodiment:

[0045] In order to further improve the contact between the cooling copper sleeve 12 and the exhaust pipe fittings, the tensioning column 10 is set to a two-section structure including an upper section and a lower section. The upper section is a truncated cone structure, and the lower section is a cylindrical structure. The diameter of the lower surface of the upper section is the same as the diameter of the lower section. When the two semi-cylinders are merged, the diameter of the cylindrical surface is between the diameter of the upper end and the diameter of the lower end of the tensioning column 10. When the cooling copper sleeve 12 is placed on the base 9, the two semi-cylinders will be stretched open by the tensioning column 10. At the same time, since the lower section is a cylindrical structure, the two semi-cylinders can be kept in a vertical state, so that the entire outer facade of the cooling copper sleeve 12 is tightly fitted with the inner side surface of the exhaust pipe sleeve, so that the cooling copper sleeve 12 is in closer contact with the exhaust pipe fittings, thereby improving the heat transfer efficiency, improving the cooling effect, and shortening the cooling time.

[0046] In a further embodiment:

[0047] In order to further improve the contact between the cooling copper sleeve 12 and the exhaust pipe fitting, the angle of the arc surface of the semi-cylinder is set to 170 degrees. When the two semi-cylinders are stretched apart, the arc surfaces of the two semi-cylinders are exactly on the same cylindrical surface, achieving a tighter fit with the inner side of the exhaust pipe fitting.
