Difference between speed And Velocity

Speed is scalar quantity and Velocity is a vector – velocity has both speed and direction.

Speed is expressed as distance moved (d) per unit of time(t). Speed is measured in the same physical units of measurement as velocity, but does not contain an element of direction. Speed is thus the magnitude component of velocity.

What is MIM? {Metal Injection Molding }

Metal injection molding (MIM) is a metalworking process in which finely-powdered metal is mixed with binder material to create a "feedstock" that is then shaped and solidified using injection molding. The molding process allows high volume, complex parts to be shaped in a single step. After molding, the part undergoes conditioning operations to remove the binder (debinding) and densify the powders. Finished products are small components used in many industries and applications.

Under Water Welding-- The Grate Mechanical Achievement

Underwater welding is performed while the welder is submerged, often at elevated barometric pressures.  This introduces a variety of challenges that require specialized skills and training that are taught at CDA Technical Institute (formerly Commercial Diving Academy).  Because of the adverse conditions and inherent dangers associated with underwater welding (also known as wet welding) divers must be trained to an exceptionally rigorous standard with highly specialized instruction.

Wet Welding

Welding underwater can be achieved by two methods: wet welding & dry welding. Wet welding entails the diver to perform the weld directly in the water. It involves using a specially designed welding rod, and employs a similar process used in ordinary welding. Here are advantages to wet welding:

Cheap and fast
high tensile strength
ease of access to weld spot
no habitat
no construction

Dry Welding / Hyperbaric Welding

Another method of welding underwater is hyperbaric welding or dry welding. Hyperbaric welding is the process by which a chamber is sealed around the structure that is to be welded. It is then filled with a gas (typically mixture of helium and oxygen, or argon), which then forces the water outside of the hyperbaric sphere. This allows for a dry environment in which to perform the weld. Here are some advantages to dry welding:

welder / diver safety
higher weld quality
surface monitoring
non-destructive testing

ASME {AMERICAN SOCIETY OF MECHANICAL ENGINEERS}

ASME {AMERICAN SOCIETY OF MECHANICAL ENGINEERS}

       ASME is a not-for-profit membership organization that enables collaboration, knowledge sharing, career enrichment, and skills development across all engineering disciplines, toward a goal of helping the global engineering community develop solutions to benefit lives and livelihoods. Founded in 1880 by a small group of leading industrialists, ASME has grown through the decades to include more than 130,000 members in 151 countries. Thirty-two thousand of these members are students.

          From college students and early-career engineers to project managers, corporate executives, researchers and academic leaders, ASME's members are as diverse as the engineering community itself. ASME serves this wide-ranging technical community through quality programs in continuing education, training and professional development, codes and standards, research, conferences and publications, government relations and other forms of outreach.
