Yuantai Derun square tube welding method
Yuantai Derun Square Tube Welding Method
- **Manual Arc Welding**: This is a common welding method suitable for square tubes of various thicknesses. The technique is easy to master and requires minimal equipment, making it suitable for field construction and small projects. To operate, first prepare the welding materials and equipment. Clean and derust the square tube. Then, adjust the current, voltage, welding speed, and other parameters. Start the arc welding machine and place the electrode at the weld joint to strike the arc, melting the electrode and forming a weld on the base material. During welding, control the welding speed and maintain a stable welding rod combustion. Finally, perform acceptance inspection and, if necessary, perform subsequent heat treatment.
- **Gas Shielded Welding**: This is an efficient and energy-saving welding method suitable for welding square tubes of various materials. To weld, first place the square tube on a stable workbench, connect the gas shielded welding machine and gas cylinder, and adjust the gas flow and voltage. Insert the welding wire into the welding torch, ignite the flame, and feed it into the weld area, maintaining the flame for a suitable time to melt the weld. After welding, sand the weld with sandpaper to remove excess metal particles and oxides.
**Submerged Arc Welding**: Suitable for large-scale projects and applications requiring high-quality welding. During welding, the welding rod is fed into the weld area using a device and welded under protection. First, prepare the welding materials and equipment, pre-treat the square tube, and then use the device to feed the welding rod into the weld seam. Current is applied to the rod to melt it. The welding speed and weld quality are carefully controlled to prevent defects such as cracks. After completion, an acceptance inspection and necessary heat treatment are performed.
**Tungsten Inert Gas Welding**: This method uses a tungsten rod as the electrode and argon as the shielding gas. It is suitable for welding thin and ultra-thin square tubes and produces high-quality welds.
**Plasma Arc Welding**: This method utilizes a high-temperature, high-speed plasma arc as the heat source. It offers advantages such as high energy density, fast welding speed, and excellent weld quality. It can be used for welding Yuantai Derun square tubes with special requirements.
In addition, according to the "Square and Rectangular Tubes for Building Structures" standard, Yuantai Derun square tubes can also be welded using high-frequency resistance welding. In actual applications, it is necessary to select the appropriate welding method based on factors such as the material, thickness, usage scenario and specific welding requirements of the square tube.
