What are the common defects in welding area of A204 Gr B pressure vessel steel sheet welding parts

Steel plate A204 Gr B pressure vessel steel sheet cutting, according to different classification standards, there are different specific types. If it is divided by cutting temperature, it can be divided into cold cutting and hot cutting. One of the cold cutting, there are water jet cutting and abrasive cutting and so on, thermal cutting is flame cutting, plasma cutting and laser cutting. In addition, we also need to know that the high-grade thick A204 Gr B pressure vessel steel sheet steel plate can be cut by flame, and its cutting is as simple as that of ordinary low-carbon and low-alloy steel, but we need to pay attention to it.

Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, A204 Gr B pressure vessel steel sheet included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of A204 Gr B pressure vessel steel sheet steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main A204 Gr B pressure vessel steel sheet production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

According to the data of the National Bureau of statistics, from January to February, the output of pig iron, crude steel and steel (excluding repetitive materials) were 132.34 million tons, 154.7 million tons and 167.13 million tons, respectively, up 3.1%, 3.1% and 3.4% year on year; the daily output of A204 Gr B pressure vessel steel sheet, crude steel was 2.5783 million tons, down 5.15% year on year.
