How to Bond Metal Brackets to a Metal Tank Without Welding


In this video, we’ll be demonstrating the pros of cold bonding versus welding We attached two brackets to a tank One was attached to the tank via welding and the other via cold bonding Before we began, we marked out the perimeter of the brackets For the welded bracket we prepared the surface area outside the perimeter since welding is done at the edges We then proceeded to weld the bracket As you can see in this video, the tank lining started burning as soon as we began welding We had to stop welding for safety reasons For the cold bonding application we prepared the area inside of the marked perimeter since bonding is done on the whole surface of a bracket We then prepared the bracket Next, we masked off the application area We proceeded to clean the area to remove any loose particles We then mixed our bonding material which in this case is Belzona 1212 After mixing we applied a thin layer to the application area with a stiff bristled brush pressing hard to make sure product fills the profile We then apply a thin layer of the product to the bracket surface and more product was applied to build a central peak We proceeded to attach the bracket to the tank but pressing with force onto the application area making sure the product squeezed out the sides We cleaned the excess product off the edges of the bracket We took temperature reading via thermal imaging as you can see in this video A maximum of 80°F (27°C) was reached which is safe for both the tank lining and its content We removed the masking tape to finish the application Cold bonding is a more practical and safe choice Here are a few samples of other cold bonding applications Live leak repair on a tank Mounting a ladder or cell phone antenna to the side of a tank Or even repairing the weld seams by injection Check out these videos on our YouTube channel

  1. 1. Please tell the one doing the grinding that the gaurd on the grinder is wrongly positioned.
    2. Just as welding is tested with NDT, What are the tests done to ensure the cold bonding is done effectively?

  2. Why not conduct all welding then apply the tank lining. Welding done correctly is always more dependable than glueing.

  3. for the above video, what is the cost of cold bonding to welding. What is the bonding strength of cold bonding to welding in the above video, if possible can I get the strength value of cold bond strength in MPa. Time taken for cold bonding making to that of welding time. can i get the data please ?

  4. Can smooth or polish surface be bonded by this? If not please recommend what should I use, to bond smooth surface..

  5. It's good and all but I would not risk my life on this stuff. If you weld a ladder to a 200m pillar, I trust it…. "glue" the ladder on with this stuff… well.. I'm not climbing that thing.

  6. If that epoxy takes a whack with a hammer, will it just break off ? How about lifting capacity compared to the weld ?
