In Civil Engineering:
1 - Pointing: Pointing is act of filling the joints 15mm to 20mm from outer surface with rich mortar (1:2 ratio of Cement and Sand). This is done to obtain various objectives from detailed work which may look beautiful to make economic use of mortar where there are not enough resources to plaster and so on.Types of Pointing are, Flush, Struck, V, Grooved, Weather, Recessed Pointing and Tuck pointing.2 - Jointing: Jointing is act of layering the constructional material (Stone, Brick or Concrete Block) and also making the Joints in Concrete slabs.Differences:1- : Jointing comes first because 'Pointing' is enhancement of joints.2- : Jointing is done to bind (adher/stick/strengthen) the constructional material where'Pointing is done to make the bonds look beautiful and become resistant against weather effects and dampness.3- : Jointing is considered basic and intrisnsic to constructional work (Also called Masonry if it is done with Bricks/Stones/Blocks), where pointing is additional favor to the building.4- : Jointing deals with how building materials are to be placed with each other and how can they strengthen each other and is aided by the mortar, hence 'Jointing' needs (1) Building Material (2) Mortar; Pointing deals with how to 'ENHANCE' the JOINT by using more MORTAR, hence it needs 'MORTAR'.Hope you have understrood now.Mirza Usmanwww.facebook.com/Mirza.Usman.Blogger

What is the differens between jointing and assembling?
jointing refers to the partial development of the wooden dimensions that naturally occur during the structural and forelan process. on the contrary assembling is the disposition in which the properties of the design occur. the contribution to the developmental stages is referred to as cattering but that is not to be confused by the other two vital stages of development.
For what type of fitting would the application of solder wire during the jointing process be required intgral ring or capillary or type a or type b?
The application of solder wire during the jointing process is typically required for integral ring fittings or capillary fittings, as these types of fittings use soldering as the method to create a secure connection between the pipes or components. Type A or Type B fittings usually do not require soldering for jointing.
What is sheet jointing?
Sheet jointing is a geological term describing the formation of fractures in rock masses due to stress, mostly found in igneous and metamorphic rocks. These cracks run parallel to the exposed surfaces of the rock and are commonly found in areas where large masses of rock are exposed to weathering and erosion. Sheet joints can influence the stability and erosion of rock formations.
What is a jack plane use for?
A jack plane is the general-purpose bench plane, used for general smoothing of the edges, sizing of wood and [edge jointing|jointing] edges. Jack planes are about 15 inches long, and the blade can have either a slightly curved edge for smoothing stock, or a straight edge for jointing stock.
