As the name justifies under water welding is done under water, they are mostly done when there is a real need or repair which has to be done in the ships, in the harbor, oil platforms and pipe lines. There are actually two types of underwater welding, which includes dry welding and wet welding. However both are done under water only but in different conditions. The dry welding is done through a special chamber that creates a very dry environment.

Our world has evolved over the years. Man has adapted to every spheres of life and made the fullest of earth's potentials. From cavemen to hunters, to inventors I can rightly say we have become technologists in today's era. Innovation and creativity had been the only source of success and will be forever.

Birth of technology hasn’t made us stagnant. It itself has evolved from its initial stages and thus has revolutionized and modernized our ways of lifestyle. We are in the age where technology can behave like humans.

Stainless steel has a low rate of thermal conductivity which causes the heat input to be localized. This localization of heating or cooling leads to distortion. The materials also undergo corrosion thanks to the localized excess heat. Experienced TIG welders know that stainless steel wraps if you do not weld it carefully with immense concentration.

Welder generator is a critical component when it comes to welding. Irrespective of whether you use them during winters or not there are some considerations you need to take for its proper usage and storage.

Normally a welding operation would generate a lot of heat. This is because of the operation of the machine that welds pieces of metal together causes the generation of a lot of heat. The heat is developed from the arc that is created which also aids in joining the metal pieces together. However excessive heat generation can harm the torch as well as the work pieces. Therefore an optimum temperature must be maintained so that the finish of the product is of good quality.

Spot welding is otherwise known as Resistance welding (RSW). In spot welding, there is some amount of heat generated when there is resistance to electric current flow. This heat is in-turn used to weld the contacting metal surfaces. The parts that are joined by this process are of 3mm thickness and the diameter varies from 3mm to 12.5mm. The amplitude, the duration of current passed and the resistance between the electrodes determines the amount of heat distributed to the spot to be welded.

Tig welding is also known as tungsten inert gas welding. In this process a non consumable electrode is used to complete the weld. This is generally meant for motorsport enthusiasts. Usually a shielding gas is used to protect the weld are from contamination from the environment.

Spot welding is a process to join two metal surfaces together. This process makes use of the heat that is generated from the resistance to the electric current that flows through the metal pieces. The two work pieces are held together with the help of electrodes. These electrodes are most commonly copper alloy electrodes. The copper alloy electrodes are used to concentrate all the electric current onto a single spot which creates a weld.

The power arc welding process is used for heavy welding applications. This process is generally used in process like shipbuilding, on the farm or for pipelines. If you are a welding enthusiasts and want to take your welding skills up another level then you should consider power arc welding.For power arc welding you should consider power arc welding.

Plasma cutting has become a popular metal cutting process. It involves the use of a plasma torch to cut through steel and other materials of different thickness. The torches works on the principal of blowing out compressed air out of the torch nozzle that would create an electrical arc that would help to cut through material of different thickness.
