Joining

Joining processes like moulding processes can also use the mechanism of material solidification initiated either by chemical reaction or melting and cooling. It is also possible for materials to remain in the solid state during joining, with bonds forming below the melting temperature of the material.

 

Solidification and Bonding Mechanism

In the Joining of Metals by welding the bonding mechanism can be both in the liquid and solid state, with heightened temperature being the catalyst for mollecular bonding between materials. Joining can also involve materials of differing melting points, the variation of the mechanism in this case means that chemical bonding may take place with one material in the liquid phase with the other in the solid phase. Joining is typically localised, with joints specifically designed to enable the solidification mechanism. The main variations within joining processes are; the source of heat, and the feeding mechanism of joint material (if there is additional joint material).

 

Diverse Range in The UK

Joining processes are central to fabrication and the creation of permanent assemblies across every industry including Automotive, Process Plant through to Rail and Infrastructure. With Joining processes being so core to many industrial sectors, the UK has naturally built up a breadth of capability to cater for projects both on the mainland, offshore and in the export market, with many British made fabrications operating in countries across the EU and further afield.

 

Processes Typically Combined with Joining

Joining processes are central to fabrication and are routinely accompanied by Bending Processes, Forming Processes and other methods of Assembly. With Joint quality being critical in many applications Inspection Processes are commonly offered in combination with Joining Processes. Finishing and Treatment processes can also be applied to reduce stresses or impart preferable properties to the material bulk or surface, whether visually or for corrosion protection for example.
