What are the standards for conducting underwater welding training and certification?

Here you can see a list of international standards. We can do Underwater Welding Training and Certification. 

1. AWS D3.6 – Specification for Underwater Welding.
2. EN ISO 15618-1:2002-Qualification Testing of Welders for Underwater Welding 
3. ASME N-516-Underwater Welding Section XI Div. 1
4. AWS D3.6M 1999

We are covering all the subjects below:

• Scuba Diving Safety
• Utilize and maintain surface-supplied diving equipment.
• Basic stick welding (SMAW)
• Implement emergency procedures for surface supply diving.
• Non-destructive tests like UT, RT, and MT
• Undertake underwater deployment in a surface-supplied diving operation.
• Underwater Welded Steel Structures
• Understand surface cutting and welding procedures
• Underwater Wet Welding and Cutting
• Underwater cutting and welding applications
• Underwater Repair Technology
• An explanation of underwater welding methods
• Professional Diver’s Manual on Wet Welding
• Explanation of underwater cutting methods
• Introduction of materials used in underwater welding and cutting.
• Codes, Standards & Specifications governing Underwater Welding
• An explanation of safety rules to be followed during welding and cutting

What is the cost of an underwater welding course?

The average underwater welding course fee starts at 5000 USD per candidate for one week of training. It depends on the location or how many days they are providing training. For example, in the USA, training fees start from $15,000 USD to $20,000 USD.

How Much Is an Underwater Welding Salary?

The average underwater welding salary is 70,000 USD annually and 35 USD to 75 USD per hour.

Which book should we study for underwater welding training and certification?

1. Professional Diver’s Manual on wet Welding
2. Underwater Wet Welding and Cutting.
3. Non-destructive Examination of Underwater Welded Steel Structures
4. Underwater Repair Technology.
5. Welding Symbols

Which equipment is needed for underwater welding?

Here you can see the list of underwater welding equipment that is used in underwater welding.

• Diving Suit: The diving suit should be flexible armor for the underwater welding job. 
• Diving Helmet: Here you can see a type of underwater welding helmet, The Eyes and Ears of Hyperbaric Welding Projects, Open Circuit, Reclaim, and Free-Flow Helmet:
• Underwater Welding Accessories: This section shows which accessories are used for underwater welding, as well as the most important attachments to use, such as a diving knife, umbilical cord, harness, gas panel and compressor, bailout gas, and a knife switch. 
• Underwater Stinger: Here you can see a type of underwater welding stinger that is insulated, ergonomic, lightweight, and angles correctly. 
• Underwater Welding Machine: Here you can see which type of machine is used for underwater welding, amperage and current matters, consistent and stable power, duty cycle, DC not AC. 
• Waterproof Electrodes: Here you can see which type of waterproof electrode is used for underwater welding. The Right Coating Goes a Long Way. It’s a water-resistant coating with a high strength yield.
