Abstract
Description
Technical Field
[0001] This invention relates to the field of argon arc welding equipment technology, and in particular to an argon arc welding gas fusion vessel and its usage method. Background Technology
[0002] Currently, in argon arc welding, the welding wire is fed through a wire wheel and conducted by a contact tip. An electric arc is formed between the base metal and the welding wire, melting both. Simultaneously, the inert gas argon protects the arc and the molten metal to complete the welding. However, this method has some drawbacks. While argon is a commonly used shielding gas with advantages such as higher density than air, better arc protection during flat welding, and reduced shielding gas consumption, its high ionization potential makes arc ignition difficult, and strict timing requirements are imposed during welding. For example, the filler wire must be added only after the base metal has fully melted, and the wire cannot be immediately removed from the argon protection zone during retraction; otherwise, slag inclusions and other problems can easily occur in the weld, affecting welding quality. Furthermore, air can affect the weld zone during welding, causing oxidation, which in turn affects the weld formation surface, leading to porosity, inclusions, uneven cross-sections, and slag inclusions. This also increases the welding time for containers, increases labor intensity, and reduces work efficiency. Summary of the Invention

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0024] The purpose of this invention is to provide an argon arc welding gas fusion vessel and its usage method to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively improves welding quality and work efficiency.
[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] This invention provides an argon arc welding gas fusion vessel, such as... Figures 1-3As shown, the system includes: a base 1, a tank 2, a clamping mechanism 3, and an air inlet cover 4. The tank 2 is fixedly connected to the base 1. The fixed end of the clamping mechanism 3 is used to fixally connect to the base 1, and the movable end of the clamping mechanism 3 is used to clamp and fix the first workpiece 6 to be welded to the tank 2. One end of the air inlet cover 4 is used to connect and communicate with an inert gas source, and the other end is used to seal and communicate with the second workpiece 7 to deliver inert gas to the second workpiece 7. After passing through the second workpiece 7 and entering the tank 2, the inert gas returns upward and flows out from the welding position of the first workpiece 6 and the second workpiece 7 to form an inert gas protective atmosphere at the welding position. The structural design makes the entire gas fusion tank structure stable, and the various components work together to effectively ensure that the inert gas reaches the welding position according to the predetermined path, forming a stable protective atmosphere, providing a good gas protective environment for argon arc welding, improving welding quality, and reducing the possibility of defects such as slag inclusions and porosity in the weld.
[0027] In a preferred embodiment, the base 1 is a rectangular steel plate. The rectangular steel plate as the base 1 has a large supporting area and good stability, which can firmly support the tank 2 and other components, ensuring that the gas fusion tank will not easily shake or shift during the welding process, thereby providing a stable foundation for the welding operation and helping to improve the accuracy and quality of the welding.
[0028] In a preferred embodiment, the tank body 2 is a circular tube, and the bottom of the circular tube is sealed and welded to the base 1. Using a circular tube as the tank body 2 has two advantages: firstly, the structure of the circular tube makes the internal gas flow smoother, which is conducive to the uniform distribution and rise of the inert gas to the welding position; secondly, the sealed welding ensures the airtightness between the tank body 2 and the base 1, prevents inert gas leakage, effectively improves the gas utilization rate, and enhances the welding protection effect.
[0029] In a preferred embodiment, the clamping mechanism 3 includes multiple clamping components, including a vertical plate 31, a nut 32, and a bolt 33. The first workpiece to be welded 6 is a plate with a through hole in the middle. The vertical plate 31 is vertically fixed to the base 1. The nut 32 is fixedly connected to the top of the vertical plate 31. The bolt 33 is used to thread the nut 32 to tighten the top surface of the plate. This clamping mechanism 3 has a simple and reliable structure. The clamping force can be easily and flexibly adjusted through the threaded connection between the bolt 33 and the nut 32, effectively clamping and fixing the plate (the first workpiece to be welded 6) to the tank 2, ensuring the stability of the position of the first workpiece to be welded 6 during the welding process, avoiding the impact of the welding quality due to the shaking of the workpiece, and ensuring the stability and consistency of the welding.
[0030] In a preferred embodiment, there are two clamping members, which are symmetrically arranged about the center point of the base 1. The symmetrical arrangement of the two clamping members can apply clamping force to the plate (the first piece to be welded 6) from both sides, making the plate more stable and further improving the stability of the welded part during the welding process. This avoids deformation or displacement of the plate due to uneven force, thereby improving the accuracy and quality of the welding.
[0031] In a preferred embodiment, the through hole of the plate is coaxially arranged with the pipe body. The coaxial arrangement allows the inert gas to rise more smoothly from the tank 2 through the through hole of the plate to the welding position, reducing airflow turbulence and obstruction, and ensuring that the inert gas forms a uniform and stable protective atmosphere at the welding position, which is beneficial to improving the welding protection effect and improving the weld quality.
[0032] In a preferred embodiment, the air intake cover 4 is frustum-shaped. The end of the air intake cover 4 with a smaller cross-sectional area is used to extend into the second part to be welded 7, and the diameter of the end of the air intake cover 4 with a larger cross-sectional area is larger than the diameter of the second part to be welded 7. The design of the frustum-shaped air intake cover 4, with the larger end having a larger diameter than the second part to be welded 7, and the smaller end extending into the second part to be welded 7, is conducive to achieving a good sealing connection and preventing inert gas leakage; it also facilitates the installation and positioning of the air intake cover 4 and the second part to be welded 7.
[0033] In a preferred embodiment, an inert gas source is further included. The inert gas supply pipe 5 passes through the inlet cover 4 and is sealed to the inlet cover 4. This clearly defined inert gas source and its sealed connection to the inlet cover 4 ensures a continuous and stable supply of inert gas to the gas fusion tank and welding position. The sealed connection prevents gas leakage during transport, ensuring the quality and stability of the inert gas supply and providing good gas protection conditions for welding.
[0034] In a preferred embodiment, the inert gas supplied by the inert gas source is argon. Argon, as an inert gas, has stable chemical properties and can effectively isolate air during welding, preventing the metal in the welding area from being oxidized. It is an ideal welding shielding gas. Using argon as a shielding gas can significantly improve the quality of the weld, giving it higher purity, better mechanical properties, reducing welding defects, and meeting the welding requirements of various metal materials.
[0035] The present invention also provides a method of using the argon arc welding gas fusion vessel as described in any of the above claims, comprising the following steps:
[0036] Preliminary preparations:
[0037] Place the base 1, made of rectangular steel plate, on a stable workbench.
[0038] The cylindrical tank 2 is sealed and welded to the base 1 to ensure a firm and airtight connection and prevent gas leakage.
[0039] Based on the dimensions of the plate to be welded (the first piece to be welded 6), the vertical plate 31 of the clamping mechanism 3 is vertically fixed to the base 1. Generally, two clamping parts are selected and symmetrically arranged about the center point of the base 1. After fixing,
[0040] The inert gas source (argon gas supply) delivery pipe 5 passes through the inlet cover 4 and is sealed. The inlet cover 4 is then installed on the corresponding equipment, with the smaller cross-sectional area end of the inlet cover 4 extending into the second part to be welded 7 to achieve a sealed connection. Ensure that the gas delivery passage is well sealed.
[0041] Welding assembly:
[0042] Make a through hole in the middle of the plate, and ensure that the through hole is coaxial with the cylindrical tank 2. Place the plate at a suitable position above the tank 2.
[0043] Using the clamping mechanism 3, by rotating the bolt 33, the bolt 33 engages with the nut 32, gradually tightening the top surface of the plate, thereby clamping and fixing the plate to the tank body 2, ensuring that the plate will not shake during the welding process.
[0044] Welding process:
[0045] Turn on the inert gas source and deliver argon gas through the gas inlet cover 4 to the second part to be welded 7. The argon gas passes through the second part to be welded 7 and enters the tank 2, then returns upward inside the tank 2.
[0046] Argon gas flows out from the welding positions of the first workpiece 6 (plate) and the second workpiece 7, forming an inert gas protective atmosphere around the welding positions to isolate the welding area from the influence of air.
[0047] Start the argon arc welding equipment and use the electric arc in the inert gas protective atmosphere to perform welding operations, and complete the connection of the first part to be welded 6 and the second part to be welded 7.
[0048] Welding completed:
[0049] Turn off the inert gas source and stop the supply of argon gas.
[0050] Loosen the bolts 33 of the clamping mechanism 3 and remove the welded component.
[0051] By using the above methods, a stable inert gas protective atmosphere can be effectively formed in the gas fusion vessel during the argon arc welding process, thereby improving the welding quality.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
