Forge welding or smith welding is the oldest known welding process and its use has been reported from 1400 B.C. This will create local plastic deformation and friction between plates which is used to create joint at interface part. ... For example, Tungsten Inert Gas (TIG) welding can employ a feeder vehicle to hold the torch and move it at a constant speed, while filler material can be fed manually. The process was developed in the (former) Soviet Union … This page introduces example cases of the improved accuracy/speed of robot welding, from groove control, weld line tracer control, and torch height control to profile inspection of tungsten electrodes. It shows the two plates to be welded placed at an inclination to each other. In these welding processes, no filler metal is used and welding does not involve a molten state of base material or filler material. Solid-state welding, alternatively called solid-state bonding, covers a wide spectrum of processes including cold welding, forge welding, ultrasonic welding, friction welding, friction stir welding, resistance welding, diffusion bonding, and explosion welding. – Examples, Advantages and Disadvantages, What is Heterogeneous Welding? Design Considerations in Welding ©2013 John Wiley & Sons, Inc. M P Groover, Principles of Modern Manufacturing 5/e . In vacuum fusion bonding the parts are held in an intimate contact in a vacuum chamber. However, application of pressure is required for getting a sound joint and thus it is also termed as Pressure welding. The essential features of the machine are that it should be able to withstand high axial pressure of the order of 50,000 N/cm2 and be able to provide a high spindle speed of upto 12,000 rpm though the usual range may rarely exceed 5000 rpm. The flow of current through the wire or strip heats it up locally thus keeping the heat confined to the small zone around it. Weldability 8. These days the process is mainly used for welding low carbon steel parts usually for agriculture implements in rural areas of third world countries. On the other hand, if no such melting takes place during welding, then it is termed as solid state welding. On the basis that base material fuses or not, welding processes can be broadly classified into two groups—solid state welding and fusion welding. Solid-state welding processes also have special joint design or part cross-section requirements. Diffusion in metals takes place due to vacant lattice sites or along grain boundaries, and is expressed by the following mathematical relationship: D0 = Constant having the same dimension as D. T = Absolute temperature at which the workpieces are held. Fusion of faying surfaces of parent materials is not necessary for weld bead formation.
