In the field of modern industrial manufacturing, welding technology is one of the key processes to achieve, and its quality directly affects the performance, reliability and service life of the product. With the continuous development of industrial technology, welding equipment is also in the continuous iterative updating. Vacuum welding furnace as a representative of advanced welding equipment, compared with the traditional welding furnace, in the performance of a number of advantages. xvacuum technology (jiangsu) Co., Ltd. deep plowing welding equipment research and development and manufacturing field, the vacuum welding furnace and the performance characteristics of the traditional welding furnace with in-depth research and practical experience. In this paper, we will compare and analyze the performance of the two from multiple dimensions to help readers clearly understand their differences and provide references for equipment selection in industrial production.

First, the welding environment comparison

(A) the traditional welding furnace welding environment

Traditional welding furnace usually work in the atmosphere, the air contains a large number of oxygen, nitrogen, water vapor and other gas components. In the welding process, these gases are very easy to chemical reaction with the welding material. For example, the metal in contact with oxygen at high temperatures will rapidly oxidize, forming an oxide film on the surface of the weld, which not only reduces the aesthetics of the weld, but also seriously affects the strength and corrosion resistance of the weld. For some active metals, such as aluminum alloys, titanium alloys, etc., the oxidation phenomenon is particularly obvious, which will lead to a decline in the performance of welded joints, pores, cracks and other defects. In addition, dust and impurities in the atmosphere may also be mixed into the weld seam, further reducing the quality of welding. Traditional welding furnace is difficult to avoid the interference of these environmental factors, making it difficult to effectively protect the stability of welding quality.

(B) vacuum welding furnace welding environment

Vacuum welding furnace through a powerful vacuum system, the furnace air pressure down to a very low level, usually maintained at (10^{-2} sim 10^{-5} text{Pa}) between, to create a nearly oxygen-free high vacuum environment. In such an environment, the contact between the welding material and the gas is almost completely isolated, which eliminates the problems of metal oxidation and nitriding from the root. vacuum welding furnaces manufactured by XVACUUM Technology (Jiangsu) Co., Ltd. are equipped with highly efficient vacuum pumping systems and advanced vacuum monitoring devices, which are able to quickly reach and stably maintain the required high vacuum level. For example, when welding high-temperature alloys, the vacuum environment ensures the purity of the weld metal and prevents harmful gases from reacting with the metal, resulting in a significant improvement in the mechanical properties and corrosion resistance of the welded joint. At the same time, the vacuum environment can also effectively exclude the impurities and gases generated in the welding process, so that the weld organization is more dense, more reliable quality.

Second, the welding process precision comparison

(A) the traditional welding furnace process accuracy

Traditional welding furnace in the welding process precision control has certain limitations. Its heating method and temperature control means relatively sloppy, difficult to realize the welding process temperature, heat input precision control. In the welding of complex structures or small parts, due to uneven heat input, easily lead to welding deformation. For example, when welding thin-walled metal components, localized overheating may cause the components to distort, warp and other deformations, affecting the dimensional accuracy and assembly performance of the product. In addition, the welding parameter adjustment of the traditional welding furnace often relies on the operator's experience, which is difficult to ensure the consistency of each welding, and the stability of product quality is poor in mass production.

(ii) Vacuum welding furnace process accuracy

Vacuum welding furnace has a significant advantage in terms of process precision. xvacuum technology (jiangsu) co., ltd's vacuum welding furnace adopts advanced heating element and intelligent temperature control system, according to different welding materials and process requirements, can accurately set and adjust the heating temperature curve. The temperature inside the furnace is monitored in real time by high-precision temperature sensors, and the heating power is automatically adjusted using intelligent algorithms to control the temperature fluctuation within a very small range. During the welding process, the heat input can be precisely controlled to effectively reduce welding deformation. For example, when welding turbine blades and other precision parts of aircraft engines, the vacuum welding furnace can control the welding deformation at the micron level to meet the high precision design requirements. At the same time, the vacuum welding furnace has a high degree of automation, can realize the welding parameters of the precise setting and stable control, to ensure the consistency of each welding process, greatly improving the stability and reliability of product quality.

Third, the applicable material range comparison

(A) the traditional welding furnace materials

The traditional welding furnace is limited by the atmospheric environment and the characteristics of the welding process, the welding of certain materials have greater difficulties. For some active metals, refractory metals and dissimilar metal welding, traditional welding methods are often difficult to obtain high-quality welded joints. For example, titanium alloy welding in the atmospheric environment, it is very easy to react with oxygen, nitrogen, resulting in the deterioration of weld properties; copper and aluminum and other dissimilar metals welding, due to the large difference in melting point, different physicochemical properties, the use of traditional welding methods are prone to weld cracking, combined with the lack of solidity and other issues. Therefore, the traditional welding furnace is relatively narrow range of applicable materials, there are certain limitations in dealing with special materials welding.

(ii) Vacuum welding furnace materials

Vacuum welding furnace by virtue of its unique vacuum environment and advanced welding process, greatly broadening the scope of applicable materials. It is not only high-quality welding of stainless steel, carbon steel and other conventional metal materials, but also for titanium alloys, high-temperature alloys, aluminum alloys and other active metals and refractory metal welding. In dissimilar metal welding, the vacuum environment eliminates the influence of harmful gases and creates good conditions for metallurgical bonding between different metals.XVACUUM Technology (Jiangsu) Co., Ltd. has successfully realized high-quality welding of many kinds of refractory and dissimilar materials by optimizing the parameters of the vacuum welding process according to the characteristics of different materials through continuous technological research and development and practical exploration.

Fourth, the quality of welded joints comparison

(A) the traditional welding furnace quality of welded joints

Due to the traditional welding furnace welding environment and process limitations, the quality of its welded joints often have more problems. As mentioned above, oxidation, porosity, inclusions and other defects in the traditional welded joints are more common, these defects will reduce the strength, toughness and corrosion resistance of welded joints. When subjected to loads, the defective parts are prone to become stress concentration points, leading to premature failure of the welded joints and affecting the service life and safety of the product. In addition, the organization of traditional welded joints is not uniform, and the consistency of mechanical properties is poor, making it difficult to meet some of the application scenarios that require stringent welding quality.

(B) the quality of vacuum welding furnace welded joints

The quality of joints welded by vacuum welding furnace has obvious advantages. In the vacuum environment, the weld metal purity is high, almost no oxide film, porosity and inclusions and other defects. The organization of the welded joint is uniform and dense, excellent mechanical properties, strength, toughness and corrosion resistance and other indicators are significantly higher than the traditional welded joints. xvacuum technology (jiangsu) co., ltd's vacuum welding furnace through precise control of the welding process parameters, so that the weld and the base material to achieve good metallurgical bonding, the formation of strong and reliable welded joints.
