A 380 mm (15 in) ball-peen hammer.

A ball-peen hammer is a type of peening hammer used in metalworking. It is distinguished from a point-peen hammer or chisel-peen hammer by having a hemispherical peening head. Though the process of peening has become rarer in metal fabrication, the ball-peen hammer remains useful for many tasks such as tapping punches and chisels.

The term hemisphere is used in three different meanings: one-half of the Earth (or other planetary or stellar body; see also New World and Old World) Eastern Hemisphere and Western Hemisphere. ...

The original function of the hammer was to "peen" riveted or welded material so that it will exhibit the same elastic behavior as the surrounding material. Specifically, striking the metal imparts a stress at the point of impact which results in strain-hardening of that area. Strain hardening raises the elastic limit of a material into the plastic range without affecting its ultimate strength. A strain-hardened material will not deform under the same low stresses as a non-hardened material. Most metals can be "worked" by such methods until they lose all of their ductile characteristics and become strong but brittle. Welding is a joining process that produces coalescence of materials (typically metals or thermoplastics) by heating them to welding temperature, with or without the application of pressure or by the application of pressure alone, and with or without the use of filler material. ... Look up Elastic in Wiktionary, the free dictionary. ... Ductility is the physical property of being capable of sustaining large plastic deformations without fracture (in metals, such as being drawn into a wire). ... A material is brittle if it is subject to fracture when subjected to stress i. ...

The ball-peen hammer is also used to expand and shape the free end of copper roves, light rivets and similar, "setting" the rivet in place to complete the joint. Peening is also the method by which steel drums are formed and tuned.

A ball-peen hammer is also known as an engineer's hammer or a machinist's hammer and may be graded by the weight of the head. The spelling ball-pein (pronounced the same way) is usual in the UK. Engineering is the application of scientific and technical knowledge to solve human problems. ... A machinist is a craftsman who uses machine tools to make parts or alter parts by cutting away excess material. ...
