2. In order to adjust the fusion ratio (the proportion of base metal in the weld metal). Under normal circumstances, the content of beneficial alloying elements in the filler metal is higher, and the fusing ratio of the bevel reduction actually increases the proportion of filler metal, so it is conducive to improving the performance of the welding process and improving the quality of the weld metal.

Anonymous users2024-02-06The purpose of beveling is to ensure that the arc can penetrate deep into the root of the joint, so that the root of the joint can be welded through, and it is convenient for slag removal to obtain better weld forming, and the groove can play a role in adjusting the proportion of base metal and filler metal in the weld metal.
The advantages are: 1) Minimize the amount of deposition of weld metal and improve productivity.
2) Penetration (welding) should be ensured and root cracks should be avoided.
3) The groove processing is convenient and conducive to welding operation.
4) Minimize the post-welding deformation of the workpiece.
The nozzle of the pressure vessel (i.e. the flange connection) clearly stipulates that the flange refers to HG T20592, and the pipe has GB T8163, GB6479, GB9948, GB5310 and stainless steel GB T14976 and GB13296 >>>More
Relief valve. safety valve
Valves used to prevent damage to equipment or pipelines such as boilers and pressure vessels due to overpressure. When the fluid pressure in the protected body reaches a specified value slightly higher than the normal working pressure (i.e., the valve opening pressure), the safety valve will automatically open and discharge part of the fluid, so that the pressure will drop. When the pressure drops to a certain value slightly below the normal operating pressure (i.e., the valve return pressure), the safety valve automatically closes, stopping the discharge of fluid and maintaining a seal. >>>More
Broadly speaking, pressure vessels generally refer to all closed vessels that bear a certain pressure, including fixed pressure vessels, mobile pressure vessels, gas cylinders, oxygen chambers, etc. So strictly speaking, gas cylinders belong to a type of pressure vessel. >>>More
The standards of various countries are not the same, and they are often not interoperable, and they are generally used for pressure vessels in which country, and they are controlled according to the standards of which country, and they cannot be simply judged whether they are good or not. For example, no matter how good the design of foreign pressure vessels is, they are designed according to foreign standards, and if they are used in China, they must meet Chinese standards. Then it makes no difference.
TOFD: I've only seen relevant introductions and live demonstrations (buy equipment, they say that the on-site practice of the national exam is in them) Because I don't do flaw detection, I don't know much about it Now, there are study classes in Beijing, and as far as I know, at least five sessions have been held, but ah, the pass rate has been low recently, 50 to 60, and you can check it through the Internet.
