Welding Tips and Tricks

In a recent thread it was suggested to use silicon bronze to repair a pin hole in aluminum, so I thought I give a try to see what happens. I welded two 1/8" Al flats, drilled a hole and went for it.

Since the aluminum melts at a lower temp that should be expected-silicon bronze and aluminum mixing kind of like steel and aluminum it isn't gonna work to well. I feel bad you had to ruin such a nice bead.
That is some nasty aluminum you have there though.

I tried yesterday too since I had it out. But tried on DC and it just wandered and rolled it up

I did use Dc for the Silbrz weld

Would Aluminum Bronze work on Aluminum?
I don't have any or I'd try it myself.

I just ordered some Alum Bronz, holy crap that stuff is more expensive than I thought it would be. $15/lb & only a 10 lb box. I have a use for at least 3 lbs of it to save a $850 part on my sheet metal break, so it is worth it.

And I'll try it on aluminum and report back.

I have a friend who is going to send me a few sticks of sil-bro to try in exchange for some codes. One day.......

I guess I'm puzzled by this thread?
I've not seen any listings for sil-bronze or alum-bronze used for joining aluminum?
Did I miss something?

I recently used some alum-bronze rod to tig braze a cast iron piece - worked very well.

I expected it to though as the A2 alum-bronze I bought was specifically listed for cast iron and Jody had done a video on it as well (much appreciated by the way ).

The initial post is completely on the wrong track. No use for sil-bro or al-bro on aluminium. But as usual we hi jacked the thread.

As stated in the completely wrong initial post, someone else in another thread talked of using silbrz to fix a hole in AL, I just wanted to give it a try and see what happens, and here we are.

I was a partial contributor to that fiasco, and I apologize. We were discussing a 16 gauge aluminum fuel tank. These phrases do not belong together, since an aluminum fuel tank should be 11 gauge, at least, and I replied on the Si-Br while thinking stainless steel, which would be more appropriate at that thickness. I opened my mouth after pouring beer down it, and confused the issue.

I have to work tomorrow, so it's beer tonight, as the vodka gets cold alongside the tomato and orange juices for various concoctions I may choose to make.

As I recall from the last podcast with Jimmy Diresta, he said always be willing to experiment. I didn't try that to see if it would work, but to see what would happen.

Below is something I did many years ago on another job, we had purge chambers for Ti parts and we'd use these Ti coupons for a test weld to see if the chamber was ready, I used Inco 62 filler just to see what would happen, I thought it looked cool and kept it all these years.
The coupon looks dark because, well it's been around awhile

Fossilized weldipede?

Fossilized centipede? Why isn't that in a museum. Gosh I better call the museum of welding up and tell them you have it.

A grass hopper walks into a bar. The barman says "we've got a drink named after you...." "Wow.." says the grasshopper. "Who would call a drink Kevin"

They have a drink named after me, too. I call it "Sex on the Beach."
My wife calls it, "Sand in the Vagina Sucks!"
