Work hardening, also known as strain hardening or cold working, is the strengthening of a metal by plastic deformation . This strengthening occurs because of dislocation movemen...

The advantages are: 1. Decrease in yield strength, therefore it is easier to work and uses less energy or force 2. Increase in ductility 3. Elevated temperatures increase diffus...

Hot working refers to processes where metals are plastically deformed above their recrystallization temperature. Being above the recrystallization temperature allows the materia...

Drawing is a metalworking process which uses tensile forces to stretch metal . As the metal is drawn ( pulled ), it stretches thinner, into a desired shape and thickness. Drawin...

The ductile–brittle transition temperature (DBTT), nil ductility temperature (NDT), or nil ductility transition temperature of a metal is the temperature at which the frac...

In materials science , ductility is a solid material's ability to deform under tensile stress; this is often characterized by the material's ability to be stretched into...

Induction welding is a form of welding that uses electromagnetic induction to heat the workpiece. The welding apparatus contains an induction coil that is energised with a radio...

The idea of using electrical data analyzed by algorithms to assess the quality of the welds produced in robotic manufacturing emerged in 1995 from research by Associate Professo...

Methods of weld testing and analysis are used to assure the quality and correctness of the weld after it is completed. This term generally refers to testing and analysis focused...

Atomic hydrogen welding (AHW) is an arc welding process that uses an arc between two metal tungsten electrodes in a shielding atmosphere of hydrogen. The process was invented by...

Manual metal arc welding is relatively slow, as much time is spent stopping to fit new electrodes and to clean slag before restarting. Firecracker welding allows a weld the enti...

Welding processes work around the melting point of the base metal and require the base metal itself to begin melting. They usually require more precise distribution of heat from...
