Welding is the process of fabrication that joins materials, usually metals or thermoplastics by causing coalescence. Coalescence is carried out by melting the work pieces or different metal parts and adding a filler material between them to form a pool of molten material that cools down to become a strong joint.

  • 1. Significance of welding in industriesIn industries like aerospace, oil and construction application of large and heavy equipments in theirprocedures and processes is a very common thing you can see. Many processes of engineering likewelding, fabrication which involves cutting, bending, and assembling of metals require much ofattention and expertise to carry out the processes without causing any harm. Such processes notonly harm the ones who are using those machines but also to the people around them. Hence, betterunderstanding and knowledge about each and every aspect of both the machines and as well theprocess is very crucial to learn prior to any such work.Welding is the process of fabrication that joins materials, usually metals or thermoplastics bycausing coalescence. Coalescence is carried out by melting the work pieces or different metal partsand adding a filler material between them to form a pool of molten material that cools down tobecome a strong joint. This technology is very much being used today in many industries to designand fabricate modern mechanics and machineries. You can see today, there is no life without themachines.When welding was started it was only carried out by blacksmiths to make ornaments by carryingout such melting and joining processes. However, welding technology advanced quickly during theearly 20th century as World War I and World War II drove the demand for reliable and inexpensivejoining methods and machines. Today it has gone through a complete evolution with machinesplaying a major role in every part of life. As the science continues to advance there are manyadvances in this area with Robot welding taking the major place in many industrial settings andresearchers. There is a speedy development in this industry and new methods are being added dayby day. In order to meet such requirement in depth understanding of the weld qualities andprocedures is very much needed as it poses many risk factors and dangers.Some of the risk factors associated with this procedure are as follows: It can be dangerous and unhealthy if the needed precautions are not taken.
  • 2. As most of the engineering procedures involve an open electric arc or flame, the risk of burns and fire is very high and this is why it is also called as a hot work process. The brightness of the weld area leads to a condition called arc eye or flash burns in which ultraviolet light causes inflammation and can burn the retinas of the eyes. In order to prevent this exposure Goggles and helmets with dark UV filtering face plates are worn. Welders are often exposed to dangerous gases and particulate matter as in the processes like flux cored arc and shielded metal arc welding smoke containing particles of various types of oxides is released.However, with the use of new technology and proper protection, risks of injury and deathassociated with welding can be greatly reduced. For this proper inspection like WeldingInspection and Third Party Inspection must be deployed within the weld process. Suchinspections will make sure that all the procedures are carried out with full safety and pose nopotential hazards with them. Apart from this proper education about the procedures and safetymeasures should be taken into action by all the welders and engineers for a safe go. Many trainingorganizations or consulting firms that offer these services work closely with clients to learn theirprocesses and requirements and make the appropriate training recommendations for them. Theyalso offer Third Party Inspection for assuring that all the work is being carried out correctlywithout leaving any flaw. For details see http://www.aqss-usa.com/training-courses.asp
