Resistance Welding of thin Aluminum
Resistance Welding of thin Aluminum
(OP)
I'm looking for information regarding resistance (seam welding?) of a thin aluminum sheet/foil parts (approx .005" thk). Part "A" is a drawn case with a flange around the edge that is .094" wide and Part "B" is a flat piece. I need to achieve a hermetic seal on the completed part.
I am admittedly way out of my element on this project and have the following questions;
1. Is this possible?
2. What are the pitfalls/drawbacks to this approach?
3. Any special design considerations for the weld area?
4. Any special preparation of the aluminum (i.e. oxidation)?
5. What is the best aluminum for this? I was thinking 1100.
5. Would laser welding be a better approach?
I am also searching for a company to do the welding for us. If anyone knows of some companies providing this service I would appreciate the info.
Thanks for any and all comments!

Is the entire assembly made of .005" thick material with one piece having a flange broke to .093"?
Would you consider an adhesive?

I appreciate both of your responses. I've bookmarked the welding advisers website for futrue refernce and found quite a bit of useful information there. As luck would have it, my project is two part. A prototype stage and then (after the usual learn by doing) a potential production stage. A few minutes before reading the latest post we settled on using an adhesive for the prototype. I have also identifed what I believe is a source for either seam sealing or welding a production part (we were questioning if the ultrasonic weld would provide the required hermetic seal).Fortunately, a question for another day. Thanks again for the input.
