What can I use to bond 304 SS to 304 SS without welding?
“I am trying to bond 304 stainless steel to 304 stainless steel without welding. A strip of stainless steel is put into place once the device is completely assembled and welding would damage sensitive electronic components. The strip of stainless steel is currently held in place with high bond-strength double-sided tape with foam between the adhesive layers. The foam helps the strip to take its shape over slight surface variations in the welded cabinet it is being affixed to. The problem is that the foam can be shifted over allowing access to what is behind the strip. Pry bars have then been used to gain access into the device. It has been difficult to find an adhesive that can allow for surface irregularities. The adhesive must be able to withstand outdoor temperature extremes, moisture, and UV since this device can be permanently installed anywhere. The adhesive must also have other special properties because the strip is installed vertically to the cabinet and it is done on a shop floor where there are a lot of people around. Any ideas?”
For such extreme environment requirements and gap configuration, a 2-part epoxy could possibly be the best solutions for this application.
