Joining, of metals

Welding is the joining of metals by the application of heat and/or pressure, with or without the addition of a filler... 

SO that crystal lattices match at the atomic level. In lattice matching, both lattice symmetry and lattice constants are matched. This concept is widely used in the semiconductor industry to produce stable thin films with a minimum of dislocations at the over layer-substrate interface [49], In the joining of metals to ceramics, lattice matching is also used in selecting compatible materials which wet [48],... 

Plastic can be joined with an appropriate solvent. Metal may be welded, brazed or soldered, but the most popular method of on-site joining of metal on electrical installations is by nuts and bolts or rivets. 

By definition, a structural bond involves the formation of a load-bearing joint between high-strength materials, typically metal, wood, ceramic, and certain plastics. The first step in the selection of a joining method should be a comparison of the relative merits of the available techniques.In addition to structural adhesives, these include a number of mechanical fastening methods, such as screws, bolts, nails, staples, and rivets, as well as metal fusion processes. Many of these techniques are usually associated with the joining of metal structures. 

Bonding. The permanent joining of metallic parts to form an electrically conductive path which will assure electrical continuity and the capacity to conduct safely any current likely to be imposed. 

Welding is the joining of metal to metal by use of heat and/or pressure. The main fume generated by consumable electrodes is iron oxide. Cadmium, chromium, beryllium, aluminum, titanium, and nickel may also be present. Exposure to welding fumes is known to be a risk factor for chronic respiratory disorders - such as pneumoconiosis, chronic bronchitis, and lung cancer (Sferlazza and Beckett 1991). 

The joining of metals nsing a technique similar to fusion welding, and a filler metal with a lower melting point than the parent metal, but neither nsing capillary action, as in brazing, nor intentionally... 

Joining of metallic parts (induction curing) or of metallic with nonmetal-lic substrates...
