Welding is an unavoidable process of modern engineering civil, electrical, mechanical, automobiles, marine aeronautical in all branches.
It is used in fabrications and erections in infrastructures and installations. It joins metals or thermoplastics. Forming a pool of molten mass the weld puddle and allowing it to cool to become a strong joint is the basis of the process of welding. For repairs to be carried out underwater, there is a separate process. That is called underwater welding. Learn more about couplings of pipelines on ข้อต่อตรง (Couplings).
If damaged ships are to be repaired, underwater welding is the basic technology to be used. It is a highly-specialized profession more employed in the oil or shipping industry and also in the defense operations.
In the case of wet welding, the operation is completed underwater, directly exposed to the wet environment. For this purpose, a different type of electrode is used. The function is carried out manually. The welder is allowed to have freedom of movement. Hence, wet welding is the most effective, efficient and economical process.
