PROCESS DESCRIPTION

In the case of cruise liners, aluminium superstructures are also installed. Sections made from this material have a weight advantage and enable higher superstructures than comparable ones made of steel. Thus, larger ships can be built, allowing larger numbers of passengers. The welding and cutting processes used to make the sections are similar for both aluminium and steel. However, the welding processes with aluminium require the use of inert gases. Thus, arc welding methods such as MSG welding (here, MIG welding) or laser beam welding are applicable, but not gas welding or flame cutting.

null Safe Handling of Gases - 10 Rules

Perform risk assessment and prepare an operating instruction.
Prior to handling compressed gas cylinders, the personnel should be instructed.
Don’t throw and always secure compressed gas cylinders against toppling.
Transport only with valve protection approved for the purpose, protected from slipping or rolling around.
Protect compressed gas cylinders against dangerous heating (< 50 °C), avoid punctual heating from open flame or radiator.
No refilling of gas in other compressed gas cylinders, prevent backflow
Labelling should not be removed or damaged.
Cylinder valves and pressure regulators must be kept free of oil and grease, operate gas supply systems only manually, when not in use close the cylinder valve.
Withdraw gas only with appropriate pressure regulator, before connecting check seal.
Don´t use damaged compressed gas cylinders, but label them and inform the supplier.
