Thermo-elasto-plastic analysis will be used to replicate the butt welded pipe joint and the residual stress will be determined. Residual stress that arises in welded joints by heating and cooling cycles during the welding process is another major factor in fatigue failure of welded structures. Welding residual stresses might lead to a drastic reduction in the fatigue strength of welded elements. In multi cycle fatigue (N > 106 cycles)‚ the effect of residual stresses can be comparable to the effect of stress

metal which was heated to a high enough temperature for a sufficient period but doesn’t melt so that grain growth occurred. The heat affected zone is also the region whose mechanical properties and microstructure have been altered due to the heat of welding. The heat affected zone undergoes sudden heating followed by rapid cooling‚ thereby containing a series of microstructures. These microstructures within the heat affected zone are basically categorized into three different zones‚ namely the grain

various corrosive chemicals. Fluoropolymer lining is normally a sheet of Teflon/PFA/Tefzel/PVDF material either stuck to the shape of the vessel/item to be lined and various sections of lined Fluoropolymer are then welded together by same polymer welding rod. This is a procedure in case of big storage vessels. Some times no glue is applied and various sections are simply welded together. As you can see there will be some air entrapped between the liner and the metal. Because of this when the lined

There are lots job aids such like jigs‚ and pipe holders available to help welders do their job and minimize the risk of injury. Special chairs and creepers are available to provide support while performing welding tasks so that bad posture is avoided. There are many causes of injury in the welding field. Common causes of injury are repetitive gripping‚ twisting‚ repetitive reaching‚ and fatigue. Many injuries are developed when there is a mismatch between the capabilities of the worker and the demands

Within the workshop health and safety is taken very seriously. Everyone has the correct PPE on at all times‚ everything in the workshop has been risk assessed and everyone gets the correct training on how to use any new tools and equipment. The tutors also make sure that everyone is aware of what risks there are before they use something within the workshop. Before every task we do we get a brief walkthrough of how the tutor wants the job done. If we do not understand the task at hand‚ then the tutor
