Bead Blasting
Bead Blasting or Shot Peening
Bead blasting, also known as “shot peening”, is a process of using circular media to dimple the surface of an object. Shot peening is like grit blasting but works on the mechanism of plasticity rather than abrasion, which removes less material andgenerates less dust. Additionally, shot peening is used to relieve the tensile stress of metal and composites, increasing its compressive strength. This process is usually reserved for delicate machine components such as gear parts, suspension springs, and turbine blades.
The Metropolitan Borough of Walsall is a metropolitan borough in the West Midlands, England. It is named after its largest settlement, Walsall, but covers a larger area which also includes Aldridge, Bloxwich, Brownhills, Darlaston, Pelsall and Willenhall. It also serves as the post town for nearby Cannock Chase District and Lichfield District respectively.
The borough had an estimated population of 254,500 in 2007.[2]
The current boundaries were set as part of the provisions of the Local Government Act 1972, with a change to the north of the borough in 1994.[3] It is bounded on the west by the City of Wolverhampton, the south by the Metropolitan Borough of Sandwell, to the south east by the City of Birmingham, and by the Staffordshire districts of Lichfield, Cannock Chase and South Staffordshire to the east, north and northwest respectively. Most of the borough is highly industrialised and densely populated, but areas around the north and east of the borough are open space.
In 1986 the borough became an effective unitary authority when the West Midlands County Council was abolished. However it remains part of the West Midlands for ceremonial purposes, and for functions such as policing, fire and public transport.
