It is distinguished from other forms of mechanical connections, such as riveting or bolting, which involves friction or mechanical interlocking.  \nWelding offers many advantages over riveting or bolting:  \n1. Welded structures are more rigid compared to structures with riveted and bolted connections;  \n2. Welding gives the appearance of a one-piece construction as against the cluttered surface of bolted or riveted connections;  \n3. Welded structures allow the elimination of a large percentage of the gusset and splice plates necessary for riveted or bolted structures.  \n4. Welding saves up to 15% of the steel weight and economies are achieved due to elimination of operations like drilling and punching, It also saves time in detailing and fabrication;  \n5. The strength of the welded joint equals or exceeds the strength of the original base metal, thereby placing no restriction on the joints;  \n6. Weld connections offer the designer more freedom for innovation in his design, make changes and to correct mistakes during erection;  \n7. Welding is practicable for almost all types/shapes of joints; for example, connection of a steel pipe column to other members;  \n8. Welding offers air tight and water tight joining of plates and hence ideal for oil storage tanks, ships etc.  \nSome disadvantages:  \n1. Skilled manpower is needed for operation and inspection of welded connections;  \n2. Welded joints are highly prone to cracking under fatigue loading - non-destructive evaluation may have to be carried out to detect defects in welds;  \n3. Costly equipment is essential to make welded connections;  \ni  \nFundamentals ofArc Welding – D05-003  \n4. Proper welding can not be done in the field environment;  \n5. Large residual stresses and distortion are developed in welded connections.  \nIn the earlier days, combination of bolting, riveting and welding was not practiced. Structures were completely welded, bolted or riveted. Today, combination of bolting, riveting and welding is commonly used in steel structures but generally combination techniques are not used in one and the same joint. The present trend is to use welding for workshop connections or splices, and high strength bolts for field joints.  \nThere are over 50 different welding processes, but gas and arc welding is most commonly employed in industrial manufacturing.  \nGas welding is a non-pressure process using heat from a gas flame. In gas welding a mixture of oxygen and some combustible gas such as MAPP (methylacetylenepropadiene) or acetylene is burned at the tip of a torch. The flame produced is applied directly to the metal edges to be joined and to a filler metal, which is melted to the joint. Gas welding has the advantage of involving equipment that is portable and does not require an electric power source. It is widely used in maintenance and repair work because of the ease in transporting oxygen and fuel cylinders. But, the process is slow compared to other means of welding.  \nElectric arc welding is by far the most popular fusion process for joining metals in commercial welding practices. In this process, the workpieces are heated to the fusion temperature by an electric arc, causing two parts to be melted and intermixed. Upon cooling and solidification, a metallurgical bond is created. Since the joining is an intermixture of metals, the final weldment potentially has the same strength properties asthe metal of the parts.  \nAlmost all structural welding is arc welding.","cbCaiuRvbCYnwaWA","https://ap.wps.com/l/cbCaiuRvbCYnwaWA","pdf",1349303,76,"English","# Introduction to Welding\n# Welding Advantages and Disadvantages\n# Welding Trends and Processes\n# Gas Welding\n# Electric Arc Welding\n# Basic Arc Welding Processes\n## Arc Formation and Heat Generation\n## Electrodes and Filler Metals","[{\"question\":\"How does welding differ from riveting or bolting?\",\"answer\":\"Welding joins metal pieces by intense heating, with or without pressure and with or without filler material.
