Applicable welding methods

Applicable welding methods

Applicable welding methods

(OP)
Hi,

I'm interested in welding several components to a thin (0.04 inch - 0.06 inch) sheet of 6061 aluminum.  The components are cut from a 1/4 inch plate of the same grade.  They will be welded such that the 1/4 inch face of the plate is butted up against the thin sheet and joined with a fillet weld.  Very little distortion can occur within the thin sheet and I need the joint to be as strong as possible.  The number of pieces being manufactured is fairly low, so we will be contracting the job out.  Cost is obviously a big consideration here.  

What are my welding method options?

Thanks alot

RE: Applicable welding methods

If you really need a fillet with little distortion, I think your best bet for welding would be "JB" weld.  Seriosly, would adhesive bonding work?  The difference in thickness between the two parts would lead to high distortion in the thin aluminum sheet.  If you have to have a weld, and don't necessarily require a fillet, could you laser or EB weld the 1/4" plate through the .04-.06" thick sheet with a seam weld?

RE: Applicable welding methods

I agree with GRoberts.  This joint configuration will undergo significant distortion if it is welded.  Laser or EB welding will minimize this.
