Modern architecture is basically a pressure vessel welding structure. Welding is the main pressure vessel manufacturing process means. The electrodes are the most commonly used welding material. Depending on the purpose and performance, Welding Electrodecan be divided into nine categories.

â‘  structural steel electrode (common low-alloy steel is also included in this category): this type of deposited metal electrode, at room temperature, the natural environment has a certain mechanical properties.

â‘¡ heat-resistant steel, molybdenum and chromium-molybdenum electrodes: These electrodes deposited metal, with varying degrees of heat to work.

â‘¢ stainless steel electrode: these deposited metal electrode, at room temperature, high or low temperatures with different degrees of resistance to atmospheric corrosion medium corrosion and certain mechanical properties.

â‘£ welding electrodes: These electrodes designed for welding the metal surface, the deposited metal at room temperature and high temperature has a certain degree of resistance to different types of wear or corrosion properties.

⑤ low-temperature electrodes: These electrodes deposited metal, in different media under the conditions of low temperature, low temperature has a certain ability to work.

â‘¥ cast iron electrode: a special type of  Cast Iron Welding Electrodes used for welding or soldering iron.

⑦ nickel and nickel alloy electrodes: These electrodes for nickel and aluminum welding, welding, or welding. Some cast iron welding electrodes and can also be used for welding dissimilar metals.

⑧ copper and copper alloy rod: such electrodes for copper and copper alloy welding, welding, or welding. Some can be used for cast iron welding electrodes and welding of dissimilar metals.

⑨ aluminum and aluminum alloy welding rod: such electrodes for aluminum and aluminum alloy welding, welding or welding
