HTS-735-11 Weld-Braze-Solder Aluminum

One common issue that continues to come up is using HTS-735-11 is not welding. True we are not melting the parent metal which is what is commonly called welding. HTS-735-11 is Brazing or Soldering both are processes of joining metals. The meaning of the term “WELD” as stated in dictionary is a (verb to unite or fuse (as pieces of metal) by hammering, compressing, or the like, especially after rendering soft or pasty by heat, and sometimes with the addition of fusible material like or unlike the pieces to be united). The term WELD simply means joining.

The second issue that follows is strength.” It cannot be strong if you braze or solder because the parent metal was not melted in the process”. Well none of the persons that raise this concern have ever used HTS-735-11 or used it incorrectly. I can make it not work too!!! The number one issue for failure is working with the HTS-735-11 rod in or too close to the flame.

Second issue is when joining two pieces BOTH pieces MUST be heated to 735 degrees F. How do you know that? Well the HTS-735-11 rod melts at 735 degrees so you can use the rod to determine the temperature, NO GUESS WORK INVOLVED!!! Once the 735 degree temperature is achieved lower the heat by pulling the torch away from the area just enough to maintain the temperature, then you can take your time and make the repair or join pieces. Let it weld slow cool, never cool with water.

I recommend you practice first if you have not used a torch much. A soda can is a great way to improve your skills. If you can keep the rod flowing on the can for 30 second to a minute without burning a hole in the can and keeping the rod liquid, you will have no problems using HTS-735-11. It is as easy as riding a bike, just takes a little practice. Anyone can weld aluminum with a propane torch!!
