bottom up GHH-II girth welder - SYU - auto tank welder
is a self-propelled submerged arc welding system applicable for bottom-up and Top-down constructed wall storage tanks. This type Of machine can serve both construction methods. The large tank, metallurgical blast furnace and hot stove which have the large steel construction are made of plate, the joint form of main structure mostly is long linear weld. The construction project is huge, but its especially fit for automatic welding.Which is the best way to weld a tank?SMAW (Shielded Metal Arc Welding): Commonly referred to as stick welding, SMAW is the most commonly used welding process today. The equipment and materials are inexpensive, portable and relatively simple to operate even in outdoor conditions. One drawback to the SMAW process is that it is slow.See all results for this questionWhen did submerged arc welding become popular in the tank industry?Submerged Arc Welding (SAW) became popular in the tank industry in the early 1980s. This process was used on lap welded bottoms and roofs and butt welded shell joints. The first use of this process took many years of education to develop a method of welding that would be clean of porosity under the surface of the weld.See all results for this question
What kind of welding is used for gas tank filler?
GMAW (Gas Metal Arc Welding): Also known as Mig welding, the GMAW process uses a solid bare wire to create the arc between the workpiece and the filler material. The wire is fed (usually automatically or semi-automatically) through a welding gun from a spool or reel.See all results for this questionWelding in Shipbuilding - dieselduckSubmerged Arc Welding (SAW) SAW effects the joining of metal by an arc formed between a bare metal electrode and the work piece. The process involves submerging the welding arc beneath granular flux particles. The flow protects the arc and molten weld metal from ambient atmosphere. A part of the flux is melted in the process. The rest is

Feb 02, 2007 · Submerged arc welding was one option, especially for the type of work performed, but submerged arc has limitations. Traditionally, submerged arc setups allowed operators to weld in set modes that favored only shallow penetration with high deposition, or Tank and Vessel Industry APPLICATIONS - LJ WeldingLJs semi-automated tank and vessel welding cells provide a complete competitive advantage in one system. They do this by reducing material handling times, improving weld quality and rapid submerged arc (SAW) deposition rates, using column and boom welding manipulators ranging up to Tank Jacking | Tank Jacking equipment - Tank WeldingDec 03, 2017 · 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. This AGW 1-U can also be used for standard bottom up or top down tank Jack-UP construction.Estimated Reading Time: 5 mins
