Adhesive bonding is also called gluing and involves applying layers of an adhesive between two items to be bound together. The type of adhesive used varies greatly depending on the purpose, material of substrates, and pricing. The adhesive could be inorganic or organic. The basic procedure for bonding items through this method includes various straightforward steps. First, the surfaces to be bound are cleaned to ensure efficiency of the adhesive. The adhesive is then applied to one or both layers and maybe allowed to rest for a short while. The surfaces are then put together with the glued sides facing each other. Depending on the type of adhesive, small amounts of heat may be necessary to complete the procedure. However, pressure is often sufficient to firmly bond the layers.
Unlike welding, brazing and soldering, adhesive bonding makes no use of heat, electricity or fuel combustion. This implies that the method poses significantly lesser hazards as compared to alternatives. However, the method does have its own unique challenges and risks that aren’t present in other methods.
Adhesive bonding leaves the application of glue only on the surfaces that one intends. This is highly attributable to the slow and precise nature of the process as compared to its alternatives. Even though methods such as soldering might achieve this level of neatness, the possibility of formation of solder beads and solder balls is still relatively high.
Soldering iron, brazing and welding all require significant knowledge, skills and experience to carry out correctly. However, a simple guide from the internet would be sufficient to carry out adhesive bonding perfectly. The fewer requirements make this option viable especially for beginners who may not have the tools, space and knowledge required for other methods.
