Spraying system As discussed earlier, the spraying system is a process of coating the surface of the workpiece in various ways. In today's era, different types of spraying systems are being used…
Electric arc spraying system is a popular coating method as it is comparatively more efficient and cheaper than other processes. This process is accomplished by melting the filler metal at a high…
Metal spraying is a process whereby molten metal is applied in a form of a fine spray to the surface of the base metal. The molten metal binds completely with the surface of the workpiece as a form of coating.
Projection welding process It is a set of resistance welding processes wherein Unionization is produced by the heat received from resistance to electric current flow through the work parts held together under…
Welding of Plastic Preface The concept of plastic welding is nearly eight decades old, when German chemists and technicians began a strict search…
Ultrasonic welding The Ultrasonic welding process is a type of solid-state welding process wherein welding is done by the local application of high-frequency vibratory energy to workpieces, held together under pressure. Introduction…
Stick electrode Stick electrode (used in manual metal arc / shielded metal arc welding) is a core wire in various sizes and thicknesses, over which the flux coating is coated. Stick…
Stick welding Usually stick welding is known as the shielded metal arc welding, wherein a flux-coated stick electrode is used to fill the joint. Stick welding is a widely used welding process…
