In recent years, PCLNG tanks using prestressed concrete (PC) for the outer shell and 9%Ni steel for the inner shell have become the main type of aboveground LNG storage tank both in Japan and overseas. Figure 1shows the structure of one of the PCLNG storage tanks now commonly constructed overseas. For the welds of the 9%Ni steel inner shell, manual metal arc welding (hereinafter called MMA) was initially used and, since the 1970s, horizontal submerged arc welding New technology in LNG tank constructionAs previously mentioned, LNG storage tanks are constructed using 9%Ni-steel which is, due to its martensitic structure, inherently sensitive to become magnetic. The sluggish nature of molten liquid metal makes the likelihood of defects due to arc blow especially significant.
AGW 1-U is a universal standard single sided Flat Bottom Tank Automatic Girth Welder (AGW) 3 Oclock welder Submerged arc automatic girth welding machines (AGW) is the machine used to automatic weld the circumferential weld inside and outside of vertical storage tank. Automatic Vert Welder AVW Vertical Welder Tank Specifications:Adopt CO2 gas shielded or mixed gas shielded for dual shield FCAW welding process. With the advantage of multiple pass low heat input welding for thin
