Underwater welding consumables are materials specifically designed to support metal joining operations performed in wet or submerged environments. These consumables must withstand high pressure, water exposure, and unstable arc conditions while ensuring strong, reliable welds for marine structures, pipelines, ships, and offshore installations.

Types of Underwater Welding Consumables

1. Waterproof Welding Electrodes

These are the most common consumables used in wet welding. They include:

• Shielded Metal Arc Welding (SMAW) electrodes with waterproof coatings

• Ferritic or austenitic stainless steel electrodes

• Low-hydrogen electrodes for structural integrity

• Nickel-based alloy electrodes for corrosion-resistant applications

Key characteristics:

• Thick waterproof coating

• Stable arc performance under water

• High deposition rate

• Controlled hydrogen content to reduce cracking
