Cutting Equipment FLAME PLANER
Gas cutting The way to cut By The heat of metal and oxygen gas. Plasma cutting The way to cut By arc discharge using the electrical energy.
Welding(assembly)painting
Welding joins metals by melting it and adding a filler metals to form a pool of molten metal that cools to become a strong joint. Energy sources: gas flame, electric arc, laser, friction.
*Submerged arc welding *Gas tungsten arc welding *Gravity welding *CO₂ gas arc welding
Weld arc is covered by a flux powder which is fed into the weld zone by gravity through a nozzle. Flux completely covers the molten metal and prevents weld from oxidization and spatter.
GTAW( 텅스텐 AW)=TIG(Tungsten inert gas) A filler metal is supplied from a filler wire.
Gravity devices use the weight of electrode and holder to produce arc movement along the joint
welding use CO ₂ gas in protective gas as a kind of gas welding GMAW(gas metal arc welding).
The finished block will be transported to the paint shop by the transporters. it was clothed through secondary,tertiary painting of the ship after the primary blasting work.
Surface preparation Surface Inspection Painting Dry Touch up Dry Final inspection (Block)
Process is similar to block As deck houses are manufactured based on the requirements of individual ship owners, building a deck house requires the highest level of technology, and experts who are able to meet the diverse needs of customers
