Underwater welding

Underwater welding

The possibility of welding underwater comes as a surprise to many people. It seems to them that using electricity underwater is not a good or sensible combination. Until recently, such a solution was not possible. This was made possible by Konstantin Khrenov. In the 1950s, he made studies of welding under the surface of the water. He found that working in a water environment was just as effective. The arc heated and melted the metal just as well. Khrenov's experiment contributed to the development of the welding industry, making it easier to repair iron shipbuilding components and other materials underwater. 

Working as an underwater welder 

In this day and age, where the development of the economy and technology is very fast, the demand for workers who can weld underwater is constantly increasing. There are more offers on the labour market than people interested in pursuing this profession. The main deterrent is the degree of danger involved in this process. 

Welding underwater largely looks similar to working on land. The main difference is that the objects being welded may be partially or completely underwater. It typically works on oil rigs, dams, locks and ships. 

A welder working underwater must familiarise himself with the technical documentation before carrying out his duties. Only on the basis of the information obtained can he select the appropriate equipment. Once he is at the required depth, he must make sure that there are no hazards in his surroundings that could complicate or prevent him from working. Once everything is in order, he can start working. He then places the electrode on the material he wants to weld and lets those working with him know that he is starting the task. 

Working as an underwater welder is one of the most forward-looking professions. Due to the high complexity of the work that such a welder has to perform, robots will not be able to replace humans for a long time yet. Extensive knowledge and a high level of dexterity are required for this profession, so automation is not possible for the time being. 

Welding methods 

There are many methods of underwater welding. Those in this profession specialise in selected techniques. In this way, they acquire skills that guarantee them high salaries. Methods used include: 

• SMAW welding, 
• MIG welding, 
• MMA welding, 
• gas welding, 
• MAG welding, 
• TIG welding. 

Due to its lowest cost, the SMAW method, or covered electrode welding, is the most popular. 

Occupational safety  

Welding underwater is not an easy job. Being in an aquatic environment for long periods of time is not a natural situation for us. This is why it poses such a high risk to human health and life. It is a job for mentally strong people who are good at performing tasks under stress. As the depth to which a diver has to descend increases, the pressure that pushes on him increases. There is no oxygen in the environment and, on top of this, the bubbles emitted during the welding still interfere with the work. 

Earnings 

Salaries in Poland for 2022 vary between PLN 13,000 and 17,000 gross per month. Abroad, we can expect even higher salaries. For example, in the United States, where this profession is much more popular, the daily rate can be as high as USD 1 000. Underwater welding is definitely a well-paid occupation, and in addition, it does not require a university degree. What is needed is a welding licence and a diver's course.
