[0002] When the welding body is welded in the self-consumption arc furnace, a series of problems will often be faced, including insufficient welding area, excessive welding bead in the weld area and oxidation of the weld surface. These problems not only increase the difficulty of subsequent processing, but also reduce production efficiency and affect product quality. Specifically, insufficient welding area may lead to insufficient bonding strength between the welding bodies, increasing the risk of cracking in the subsequent production process; excessive welding bead at the weld may cause edge arc in the subsequent production, with the risk of breaking the crucible; and the oxidation phenomenon of the weld color may affect the quality of the final product.
[0003] In addition, the process of welding the welding body in the furnace is extremely tedious, and needs to go through multiple steps such as evacuation to exclude air in the furnace, welding operation, cooling to a safe temperature, inspection of welding quality and cleaning of residues in the furnace.

[0032] Example 1:
[0033] like Figures 1-4 As shown, a vacuum welding box welding fixture includes several first discs 1, second discs 2, and rollers 3. The first discs 1 are clamped onto the rollers 3, and the second discs 2 are clamped at both ends of the rollers 3. Two rollers 3 are arranged in parallel. An ingot 41 is placed between the first discs 1 of the two rollers 3, tangent to the first discs 1. Support columns 7 are provided at the bottom of both ends of the rollers 3, and the welding fixture is fixed to the bottom support surface 6 by the support columns 7.
[0034] Preferably, the spacing of the first disk 1 can be set according to the length of the ingot 41;
[0035] Preferably, the upper and lower parts of the disc are fixed as a whole by fasteners 8, and the disc is a hollow disc with the same inner diameter as the roller 3.
[0036] Preferably, two rollers 3 are arranged in parallel to ensure that the ingot 41 can be placed stably and subjected to uniform pressure during the welding process.
[0037] Its working process is as follows:
[0038] The first disc 1 and the second disc 2 are fitted onto the roller shaft 3 to form a stable support structure. The two roller shafts 3 are placed parallel to each other, ensuring a suitable distance between them to accommodate the ingot 41. The ingot 41 is placed on the first disc 1 between the two roller shafts 3. The ingot 41 should be tangent to the first disc 1 to ensure uniform heat and pressure distribution during welding. The position of the ingot 41 is adjusted as needed to ensure it is centered on the welding fixture or in the desired position. In the vacuum welding chamber, the welding equipment is started to begin welding the ingot 41. Since the welding fixture is stably fixed on the bottom support surface 6 and the ingot 41 is in close contact with the first disc 1, high-quality welding results can be obtained. During the welding process, welding parameters (such as welding current, welding speed, etc.) can be adjusted as needed to obtain the desired welding effect.
[0039] Example 2:
[0040] like Figure 5 As shown, a vacuum welding box welding fixture includes several first discs 1, second discs 2, and rollers 3. The first discs 1 are clamped onto the rollers 3, and the second discs 2 are clamped at both ends of the rollers 3. Two rollers 3 are arranged in parallel. Electrode blocks 42, clamped by a welding fixture 5, first fixture beam 51, and second fixture beam 52, are placed between the first discs 1 on the two rollers 3. The positions of the first fixture beam 51 and the second fixture beam 52 are both higher than the first discs 1. The welding fixture 5 is tangent to the second discs 2, meaning it is in close contact with them. Support columns 7 are provided at the bottom of both ends of the rollers 3, and the welding fixture is fixed to the bottom support surface 6 by the support columns 7.
[0041] Its working process is as follows:
[0042] The first disc 1 is clamped onto the roller 3 to ensure a tight and stable fit; the second disc 2 is clamped onto both ends of the roller 3 to ensure a tight fit as well; the two rollers 3 are arranged in parallel with consistent spacing between them; the welding fixture 5 is placed on the second disc 2 between the two rollers 3, and the electrode block 42 is securely clamped by the first fixture beam 51 and the second fixture beam 52, with the positions of the first fixture beam 51 and the second fixture beam 52 higher than the first disc; in the vacuum welding chamber, the welding equipment is started, and the electrode block 42 is welded by the second disc 2.
[0043] Preferably, the welding fixture 5 is in close contact with the second disk 2 to ensure the stability and rigidity of the entire tooling structure; the first fixture beam 51 and the second fixture beam 52 serve to fix the electrode block 42 and the workpiece, preventing them from moving or deforming during the welding process.
