Emergency underwater welding is a critical process used to repair ships and structures submerged in water, often performed in urgent situations to prevent further damage. It involves specialized techniques and equipment to ensure strong, watertight welds despite challenging underwater conditions. Underwater ship repair combines welding with other maintenance tasks to restore vessel integrity and functionality swiftly.
Emergency Underwater Welding and Underwater Ship Repair specifications:
Size: Typically 3-6 mm diameter electrodes for wet welding, larger for hyperbaric dry welding.
Grade: E6013, E7018, or specialized underwater electrodes like Broco SofTouch.
Viscosity: Water-resistant flux with low viscosity for stable arc in wet conditions.
Buoyancy: Electrodes may include buoyant coatings to prevent sinking during use.
Material: Mild steel, stainless steel, or nickel-based alloys for corrosion resistance.
Operating Depth: Up to 50 meters for wet welding, deeper for dry hyperbaric welding.
Current Type: DC (direct current) with reverse polarity (electrode positive).
Voltage Range: 25-40V for wet welding, higher for dry welding.
Shielding: Gas bubbles from flux or external gas supply in dry habitats.
Hydrogen Control: Low-hydrogen electrodes to minimize cracking risks.
Coating: Waterproof coatings on electrodes to prevent moisture absorption.
