Question 1990 Deck Safety

The correct answer is A) electric arc. Electric arc welding is the primary type of welding employed in shipyards. This is because electric arc welding is a versatile and effective method for joining metal components, which is essential in the construction and repair of ships. The electric arc creates intense heat that fuses the metal together, making it suitable for welding thicker materials commonly used in shipbuilding. The other options are not the predominant welding methods used in shipyards. Brazing (B) and thermite welding (C) are not as commonly used, and pressure welding (D) is more specialized and less widely utilized in the shipbuilding industry.
