εγω το βρίσκω αστειο 
:D.το αρχιδοπλοιο.ή αλλιως LNG(liquified natural gas)
τα πιο δυσκολα στην κατασκευη πλοια μαζι με τα μεταφορας χημικων και LPG

drawbacks.
Disvantages of Friction / Inertia Weding
(i) The use of this process is restricted to flat and angular butt welds, where one part is normal to the other part.
(ii) So far the process has been applied only to the joining of small pieces in the form of bar stock.
(iii) Sometimes, quite a heavy flash is forced out in all inertia and friction welds.
(iv) If tubing is welded, flash may have to be removed from inside the joint.
(v) Flash from medium and high carbon steels being hard, must either be removed while it is hot or annealed before it is machined.
(vi) Thrust pressures in inertia welding will range from 700 to 2800 kg/cm2, which requires a heavy rigid machine.
