The Drydock - Episode 289
🕑 Added 2024-03-16 09:00:07 +0000 UTC00:00:00 - Intro
00:01:04 - How much do scrap warships cost?
00:05:22 - Why did the IJN have so much difficulty designing the oxygen system for the Type 93 torpedo?
00:10:38 - When you see the cut down rear funnels on RN destroyers, apparently to improve their AA gun arcs, does this have any impact on their steaming?
00:15:01 - Japan's well deserved reputation for awful POW treatment was thoroughly documented by the end of WW2. Was their treatment of foreign prisoners always so bad? Or did it steadily get worse as the military dictatorship took over?
00:21:47 - What happened to IJN gunnery by the time of Leyte Gulf?
00:26:47 - Is there still a risk of radioactive contamination on the Operation Crossroads wrecks?
00:31:31 - How much more capable would Allied designs be if built to the same displacement as Kriegsmarine ships?
00:37:11 - Did ships use other material before the metal plating in order to slow down/disrupt the incoming projectile.
00:40:37 - Type of welding used on ships?
00:43:08 - Should the USN have focussed on battlecruisers instead of battleships in the later 1910's?
00:46:54 - SMS Emden commandeering the Cormoran?
00:49:17 - Questions about boilers?
00:54:39 - In the movie Nate and Hayes, a German iron ship with single gun turret is disabled by placing a shell at the turret rotation stop, which detonated when the turret is rotated to contact its fuse. Was this even a possibility with such shells of this or any period?
00:56:47 - Could you tell us a bit the painting “The Fighting Temeraire” by JMW Turner and the context in which it was painted?
01:00:31 - How hot would a gun have to be to cook off a round?

Currently oxy and TIG are used for thin and/or specialised materials. I hope this clarifies the situation. Similar considerations apply to aluminium fabrication, where MIG (wire feed with argon or other) shielding is the general process of choice.

Ship Welding Processes I have done a little welding, both gas and arc. Also I have spent most of my working life designing and supporting the construction of steel vessels. During this time I have seen some very high power welding machines in action. These are way beyond stick or later wire feed hand welders. Both gas and arc welding processes work by fusing the adjacent parent metal, and then adding filler material. Were the arc welding scores is in the rate of heat input, and thus kg of weld metal deposited per welder (operator) hour, and thus the cost per kg deposited.
