Four important points for sheet metal processing
Four important points for sheet metal processing: 1. When using Gas Metal Arc Welding (GMAW) and FCAW to weld steel (sheet metal processing cabinets) workpieces, if the plate thickness of the workpiece exceeds the maximum welding current that the welding machine can reach, how will it be treated. The solution is to preheat the metal before welding. Use propane, standard gas or acetylene welding torch to preheat the welding area of the workpiece, with a preheating temperature of 150-260 ℃, and then proceed with welding. The purpose of preheating the metal in
With the advancement of technology and the development of society, people's demand for sheet metal processing products is increasing and not decreasing. In contemporary people's lives, sheet metal processing products are everywhere and have been widely used in aviation, ships, rail transit, automobiles, computer cases, communication case cabinets, medical equipment, instruments and other fields.
What should be noted during the welding process of the sheet metal frame?
Sheet metal frame is a professional machine equipment mainly used for stamping, bending, forming, splicing and other processing work in sheet metal manufacturing. So, the editor of the sheet metal processing factory will talk about the following points to pay attention to during the welding process of the sheet metal frame: 1. Preparation work: Before starting welding, it is necessary to ensure that the sheet metal material meets the technical requirements and is free of defects such as cracks, pores, and slag inclusions. At the same time, clean the sheet meta
Several Methods of Sheet Metal Numerical Punching
Numerical punching is a very important step in sheet metal processing. Compared to traditional punching machines, numerical punching has greatly improved processing efficiency; It also plays a significant role in improving the problems in mass production of sheet metal parts and complex sheet metal processing. In sheet metal processing, there are several main processing methods for numerical punching:
Detailed explanation of the main processes of sheet metal processing
Sheet metal processing includes traditional methods and process parameters such as cutting, punching, bending and forming, as well as various cold stamping mold structures and process parameters, various equipment working principles and control methods, as well as new stamping technologies and processes. Common sheet metal processing techniques include:
What are the commonly used materials for sheet metal processing?
Sheet metal processing mainly relies on metal materials, and commonly used materials for sheet metal processing include: 1. Galvanized steel plate SECC The substrate of SECC is a general cold-rolled steel coil, which becomes an electroplated product after undergoing degreasing, pick
