Bonding a corner joint involves some thought about the forces the joint is going to be experiencing, as this will determine the type of fastening method required. Tensile, sheer, peeling and cleavage stresses can all play a part in the effective bonding of a corner joint, which can be harder than you might think.
Adhesive and Tape
It’s obvious that using adhesive and tape is the fastest and easiest way to bond two parts together, but if the two surfaces are quite small, it can be difficult to get them to stick. Changing the fastening method to either riveting or welding is certainly one way you could overcome these difficulties, or you could simply choose an adhesive or tape that is designed with the smaller surface area in mind.
Conformable, soft foams are particularly helpful when bringing rounded surfaces together without mess or stress. You could also simply replace the tubing shape from round to square, for example, to make the surface area larger. The other alternative if the adhesives don’t make the grade is to redesign the existing joint. As long as the stress is distributed evenly across the largest possible area, you can’t go wrong with either choice.
There are four key types of stresses you can experience when bonding a corner joint: tensile, sheer, peeling and cleavage. These need to work to the strength of the bonding type you use.
You also need to consider the material the joints are made of, whether it is plastic, metal or wood.
The most effective adhesives
Without a doubt, the hardest task is bonding metal to metal. You need to use the exacting proportions of adhesive as detailed by http://www.ct1ltd.com/product-applications/metal-to-metal-adhesive/. When choosing the right metal bonding adhesive, you need to make sure that you have the ability to adhere to the requirements, such as the amount of time it takes to set and the requirements for curing heat.
To achieve the best results, you need to keep in mind adhesives that fill gaps and thick foam tape can alter joints’ dimensions. If fit is particularly important, you definitely need to take this into consideration. Preparing the surfaces correctly and following the instructions on the fixing agent to the letter, you will have professional-looking bonded corner joints in no time at all.
