Forging dates back to ancient times and was associated with the village blacksmith. Virtually all ductile metals may be forged by first preheating the work piece to a forging temperature. The work piece can be a billet, a ... Read More...
Castings are made by pouring molten metal into a recessed-mould or die. When the metal cools it takes the shape of the mould or die. Ferrous alloys, Copper alloys, Aluminium alloys, Tin alloys, Magnesium alloys etc can a... Read More...

High Carbon Steel
This material is one of the earliest cutting materials used in machining. It is however now virtually superseded by other materials used in engineering because it starts to temper at about 220oC . This s... Read More...
The combined effect of alloying elements results from many complex interactions resulting from the processing history, the number and quantities of constituents, the heat treament, the section shape etc etc.. Some basic rule... Read More...

It is accepted that it is reasonably accurate to use properties based on unit weld thickness in calculation to determine the strength of welds as shown in the examples on this page. The weld properties Ixx Iyy and J are assu... Read More...
Important note: The methods described below is based on the simple method of calculation of weld stress as identified in BS 5950- clause 6.7.8.2 . The other method identifed in BS 5950 - 1 clause 6.7.8.3 as the direction method... Read More...
