Processing technology: 1Plastic deformation is carried out by hot processing processes such as hot forging, hot rolling and hot extrusion. Hot forging can improve the uniformity and texture of the alloy and improve its mechanical properties by pressing and forging at high temperatures. Hot rolling is the process of heating an alloy to the right temperature and rolling it to produce plates, sheets, and bars. Hot extrusion is suitable for the manufacture of rods and tubes. 2.Plastic deformation is carried out by cold working processes such as cold rolling, cold drawing and cold extrusion. Cold rolling produces sheets, sheets, and strips with high dimensional accuracy and surface quality. Cold drawing is often used to produce bars and can improve the mechanical properties of alloys. Cold extrusion is suitable for the manufacture of small diameters and thin wall thicknesses. 3.Machining is carried out by conventional machining processes such as turning, milling, drilling, and grinding. When machining, it is recommended to use carbide tools and choose the right cutting data and coolant to obtain high efficiency and excellent surface quality.
Some common processes for welding:1TIG (Tungsten Inert Gas) TIG welding: suitable for the welding of thin plates and small diameter pipe fittings. In TIG welding, an inert gas (usually argon) is used to protect the welded area against oxidation and nitriding. Welding operations need to control the welding current, welding speed and welding arc length to ensure the welding quality. 2.MIG (Metal Inert Gas) is a commonly used semi-automatic or fully automatic welding process, which is suitable for large-area welding. In MIG welding, a shielding gas (usually an inert gas) is provided in the welding area to prevent oxidation and nitriding. The welding operation needs to control the welding current, welding speed and welding wire feeding speed to ensure the welding quality. 3.Arc welding: It can be divided into two types: manual arc welding and automatic arc welding, which is suitable for the welding of plates, bars and weldments. In arc welding, the weld area is heated by an electric current and arc, and filler material may need to be added. Welding operation needs to control welding current, welding voltage, welding speed and welding process parameters.
When performing welding, you need to pay attention to the following:
Select suitable welding materials and filler materials, it is recommended to use nickel alloy welding wire of the same or similar composition;
Control the shielding gas in the welding area to prevent oxidation and nitriding;
Preheating and post-heat treatment to help reduce deformation and cracks in the weld area;
Strict control of welding parameters to ensure welding quality and performance.
