Hot pressing welding technology is an advanced process that uses high temperature and high pressure environment to make different materials inter-molecularly penetrate and fuse at the microscopic level. In the manufacturing process of stainless steel woks, this technology is cleverly applied to the production of composite bottoms. Composite bottoms are usually composed of three layers of materials: a stainless steel layer, a high thermal conductivity aluminum (or copper) middle layer, and a stainless steel layer again. This sandwich-like structural design is designed to combine the corrosion resistance and high strength of stainless steel with the excellent thermal conductivity of aluminum (or copper).
Through hot pressing welding technology, the molecules of these three layers of materials will penetrate and fuse each other under high temperature and high pressure, forming a new and almost inseparable composite structure. This process not only ensures the high-strength connection of the composite bottom, enabling it to withstand various stresses during cooking, such as expansion and contraction at high temperature and impact force when ingredients are stir-fried, but also greatly improves the heat conduction efficiency of the wok.
During the cooking process, the wok needs to withstand various stresses from ingredients, flames, and user operations. Traditional stainless steel woks, due to the high strength and corrosion resistance of their own materials, are often able to cope with these challenges well. However, when it comes to composite bottoms, traditional welding methods often have difficulty ensuring a firm connection between the layers of materials. Once the connection becomes loose or falls off, it will not only affect the heat conduction efficiency of the wok, but may also cause safety hazards.
The introduction of hot pressing welding technology effectively solves this problem. Through the mutual penetration and fusion of molecules under high temperature and high pressure, an almost inseparable tight connection is formed between the layers of materials in the composite bottom. This connection is not only strong, but also stable, and can withstand various stresses in the cooking process for a long time. Therefore, stainless steel woks made with hot pressing welding technology have excellent durability and can accompany users through long cooking times.
Heat conduction efficiency is one of the important indicators for measuring the performance of a wok. It determines the speed and uniformity of heat transfer from the flame to the ingredients. Traditional stainless steel woks, due to the limited heat conduction performance of their own materials, often find it difficult to transfer heat evenly to the entire bottom of the pot in a short time. This not only prolongs the cooking time, but may also affect the taste and nutritional value of the ingredients.
The stainless steel wok made with hot-press welding technology has achieved a qualitative leap in this respect. Due to the excellent thermal conductivity of the aluminum (or copper) middle layer in the composite bottom, heat can be quickly transferred from the flame to the entire bottom of the pot. At the same time, due to the close connection between the stainless steel layer and the aluminum (or copper) layer, heat is hardly lost during the transfer process. Therefore, the wok using this technology can reach the ideal cooking temperature in a short time and maintain temperature uniformity. This not only improves cooking efficiency, but also allows the ingredients to absorb heat and seasoning more fully, thus presenting a more delicious taste.
In addition to durability and thermal conductivity efficiency, stainless steel woks made with hot-press welding technology also bring users a better cooking experience in other aspects. For example, due to the design of the composite bottom, the wok can reduce heat loss during heating, thereby reducing energy consumption. This is undoubtedly an important advantage for modern families pursuing energy conservation and environmental protection.
Due to the easy-to-clean nature of stainless steel, stainless steel woks made with hot-press welding technology are also very convenient to clean. Whether using a dishwasher or washing by hand, stains and residues can be easily removed. This allows users to focus more on cooking rather than spending a lot of time on cleaning.
