Submarine hammer drilling, often referred to as underwater percussion drilling, is an advanced technique utilized primarily in marine construction and resource exploration. This method combines the principles of traditional drilling with hydraulic and pneumatic operations, enabling the effective penetration of hard substrates beneath the sea floor. In this article, we will explore the processes, equipment, advantages, and applications of submarine hammer drilling.

- Metalworking In metalworking, tools often require heavy-duty performance combined with finesse. A fractional head hammer can help in shaping metal sheets while providing the strength needed to drive rivets or other fasteners. Its ability to control the impact makes it an essential tool in fabricating metal constructs.

2. Marine Construction When constructing offshore platforms, bridges, or wind farms, the stability of foundations is paramount. Hammer drilling provides a reliable method to secure pilings and conduct deep foundation work, ensuring that structures can withstand harsh marine conditions.

The Manufacturing Process

It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
