What are the welding advantages of stainless steel coil?
Stainless steel coil should be mastered, cold-rolled plate has many types, can be classified according to the appearance and standard or according to the processing technology. For example, the difference between C-type roof purlins and Z-type roof purlins depends on the focus. In general, type C goods are 90 degrees, and type Z goods can not do that focus, only about 60 to 75 degrees. Therefore, the application of steel purlins with different inclinations is not the same.
In terms of function, the structural mechanical effect of the strong axis and the weak axis of the cold drawn C-type roof purlin is very different, so its structural mechanical effect must be different. Therefore, in the process of processing, there are strict regulations on the standard and material selection of cold-rolled sheet. The bearing capacity of the steel frame structure with different cross sections is different from that of the steel frame structure with different working conditions. Because of this kind of purposeful application advantages, there are different products and great role advantages in the application.
Together, we must talk about the strength index value of the cold-rolled sheet, that is, the material can resist the working pressure of the surface hard block. According to different experimental methods and application scale, cold-rolled sheet can be divided into Brinell hardness, Rockwell hardness, Vickers hardness, Shore hardness, microscope strength and high temperature strength.
Bearing steel ball or cemented carbide ball with a certain diameter is used to press Brinell hardness of cold-rolled plate into the surface of the pattern with standard test force. After the standard maintenance time, the test force is removed and the diameter of the specimen surface is measured. The Brinell hardness value is the value obtained by dividing the test force by the surface area of the impression ball. In the strength standard of cold-rolled sheet, Brinell hardness is widely used and convenient to visualize.
In addition, the butt weld of stainless steel coil cold-rolled sheet is specified as a butt weld in the flat welding direction, capable of high speed electric welding, and has a considered weld path for single and double side welding and two side forming. These aspects must be manipulated by improving the main parameters of the welding and selecting a single pulse low temperature plasma arc welding.
