Welding method of Qingdao common plate flange air duct

The following is a brief introduction to the welding method of Qingdao common plate flange duct, hoping to help you better understand Qingdao common plate flange duct.

Method 1: Manual welding of stainless steel plate and stainless steel duct factory is widely used. The operation process is relatively simple. The key is manual adjustment. Stainless steel welding wire should be added as raw material when welding. Manual welding machine is usually raw material that can be welded even outdoors. Therefore, it has good adaptability. Welding generally uses DC stabilized power supply. Welding rod is stainless steel plate, which can weld titanium and metal materials. Titanium welding rod is easy to weld. Customized flange common pipe is beautiful and easy to weld, the disadvantage is that it is also very easy to weld.

Mode 2: Metal gas shielded welding, which belongs to gas shielded welding, is also a welding rod specializing in the production of flange air ducts. Under the action of gas protection, steel, non-carbon steel, ferritic stainless steel and high aluminum alloy profiles can be used for gas shielded welding of metal materials and are widely used. However, the gas it contains is a special gas, such as carbon dioxide or mixed gas. The disadvantage is that commercial workpieces cannot be wet if welded outdoors, otherwise it will get wet.

Method 3: The arc of TIG arc welding is formed between TIG welding wire and commercial workpiece, so the maintenance gas is pure argon gas cylinder, the welding wire is not easy to be charged, and can be sent manually, by mechanical equipment, or sometimes without sending. Then, DC regulated power supply and AC circuit are welding raw materials, TIG welding is suitable for welding commercial workpieces with medium thickness and vertical thickness, and its raw materials are very common, such as carbon steel, aluminum, magnesium, etc.

　　Qingdao common plate flange air ductThe manufacturing steps:

1. The standard connecting pipe should immediately form a complete flange on the production line.

2. Rear non-standard pipe ports, elbows, tees, crosses, spare parts, etc. When cutting, TDF flanges are formed on one machine.

3. The flange corner is instantly formed by the stamping die of the grinding tool, and the four corners can be clamped during installation.

4. The connection between flanges adopts flange cards made of galvanized sheet. The flange cards are cut into uniform specifications by flange card forming machine, which is convenient for installation and connection. TDF common plate flange air duct is connected with thick steel plate of pipeline as a whole, without opening and riveting like angle steel flange. A special flange card is placed at the connection of two pipelines. The four corners are connected by screws to form 90-degree flange angles. The actual operation is simple, the efficiency is improved, the appearance is uniform and smooth, product quality is stable.
