Underwater welding is a challenging but rewarding career for anyone who loves adventure. The main duties of professionals in the career involve different procedures that are carried out underwater. The procedures are dangerous and the professionals who do them must be well-trained and skilled.
What is Underwater Welding?
Underwater welders are usually required to have more advanced diving skills than commercial divers. The professionals carry out different welding procedures on steel underwater. They may be involved in welding ships, offshore oil platforms and pipelines. Companies usually prefer welding the steels underwater mainly because of time and money. It is more costly and time consuming to remove the steels from the water to have them welded.
Underwater welding is usually carried out by professional welders working in teams. To pursue a career in the trade, one must have formal training in school.
Types of Underwater Welding
There are two main types of underwater welding: dry and wet welding. Both of the procedures fall under a high pressure welding method known as hyperbaric welding. In hyperbaric welding, the procedures are done under completely dry conditions. Before welding is done, any water that is around the area to be welded is enclosed in a chamber and pumped out. This leaves the environment dry and enables the underwater welder to perform the welding easily.
The Dangers of Underwater Welding
There are a number if dangers that underwater welders face when carrying out their duties. If you want to pursue a career in underwater welding, you should be adventurous and ready to visit different locations. You should also be aware of the dangers that you may face when doing your work. Some of the dangers include:
- Accumulation of nitrogen in the bloodstream during welding—To counter this, underwater welders have to go on site in teams and are provided with decompression chambers.
- Explosion— When hydrogen and oxygen packets combine and are ignited, they can explode. This can lead to an underwater explosion.
- Electric shocks—Welders can get electrocuted while welding underwater. To counter this, they are provided with equipment that is adaptable underwater. When doing the work, it is important to keep the welding current under control and to switch off the power immediately the welding has been finished.
- Hypothermia—Welders are at a risk of getting hypothermia since water conduct heats from the diver better than air. Some symptoms of the condition include imparted judgment and dexterity.
- Shallow water blackout—This can occur when the partial pressure of oxygen level mixes with carbon dioxide within the lungs. This usually makes a person drown.
Since underwater welders go on site in teams, they are always in contact with their colleagues on land and can call for help any time they face any dangers. While underwater, the welders get air supply from breathing apparatus similar to those used by scuba divers.
Underwater welding is a rewarding career for the adventurous person. However, it is also dangerous. Proper formal training must be done for one to progress sin the career.
