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

Introduction Welding has always caught my attention as a kid‚ and growing up I’ve always wanted to do it. In addition‚ I was always breaking things that needed to be repaired with a welder‚ but I didn’t know how. I first heard about this program from a lady in Cadillac. I bought a speed boat from while I was in middle school. She worked/works at the C.T.C. but‚ I don’t remember her name. That’s when I made my decision that I wanted to join this class. Reflection With zero experience in welding beforehand

Welding: Creating the World “Every building is a prototype. No two are alike.” (Helmut Jahn). Every welder has their distinct technique; no two welders weld alike. Indeed‚ welders are the ones responsible for the structure of a building by welding to pieces of metal together they are slowly placing it together. The education needed for a welder is basic all you need is a high school diploma. Their job responsibilities are melting two pieces of metal together. Depending on their employer will depend
