Remote control technology provides welding operators with the ability to set welding parameters at the joint, increasing safety by reducing trips to and from the power source, and increasing arcon time for greater productivity. This technology also helps improve quality by eliminating the need to settle for lessthanoptimal settings.
A total of approximately 4,500 underwater wet welding electrodes were used to restore the cavitated/eroded sections of the rudders. In some loions, the original plate thickness of 19⁄16 inches was deteriorated to 5⁄16 inches. It took the dive teams six attendances, each lasting 2 weeks, to repair the damages.

· Often, wear plate will be welded to a plain carbon steel structure only in the areas that experience abrasive wear. Since wear does occur, wear plates need to be replaced frequently, which makes this a very common welding question. Although these materials are very weldable with many processes, there are three things to consider when welding wear plate to .
· 5. Visual test for welding (this is one of the initial tests on steel structure) Of all the welding tests, visual inspection is one of the simplest tests on steel structure. But it is also the most underrated and underestimated because you do not need to use any equipment. Because of that, it is inexpensive and quick to perform.
· Reason No. 3: Loose connections. Consumable connections play an important role in gun performance. Consumables should be tightly secured to the gun, and all threaded connections should also be secure. It's especially important to check and tighten all connections after a gun has been serviced or repaired.
