Bernd --- End quote --- OK, I posted the link because I had a good laugh listening to a good ol' boy breaking rap and you guys want to talk about some crap rod that they sell at flea markets. If you are serious about brazing aluminum go to Kent Whites site and invest some time in reading, then buy his product and get the job done. Kent's website: https://www.tinmantech.com/index.php Link to Kent's soldering and brazing stuff: https://www.tinmantech.com/html/brazing_soldering.php Link to Kent's article on The Metalshapers Assn. website: http://metalshapers.org/tips/white/aluminum-welding/index.htm Link to Kent's article:WELCOME TO OUR SECTION FOR THE HUMBLE OXY-ACETYLENE TORCH https://www.tinmantech.com/html/oxy-acetylene_torch.php Link to the Index of some of Kent's published articles: https://www.tinmantech.com/html/articles.php Yes, Kent is a real metal god with the credentials to prove it. Yes, Kent sells his stuff, he also backs it up with good customer service and helpful advice. No, I don't make anything from referring people to Kent, just a very happy customer. |

Bernd I have never tried using that for welding aluminum. I had just remembered others talking about it awhile back so thought I would post it for what it was worth. I had tried to weld aluminum once in a similar fashion to brazing but with aluminum wire. I didn't have any luck. Either it wasn't hot enough to melt or it melted and disappeared. There didn't seem to be any in between. Definitely different than welding steel. :lol: :lol: Cheers :beer: Don Edit: I started to post this message BEFORE Roger posted his message. In the mean time Roger posted his message. This message was in reply to Bernds message. My next message is in reply to Rogers message. Hope this explains the order of the messages. Don |

Roger I did go to the link and watched the video in question and did get a good laugh after I was able to catch my breath. I also watched about 6 or so other video's before I came back and posted the link that I did. If you read my posts It explains why I posted it and also that I did thank you for posting the link. I guess that I should apologize for posting the off topic link and hijacking the thread with what I thought would be a helpful bit of information. I am sorry Roger. Can you ever forgive me. :( :( cheers :( Don |

I don't know. Bernd --- End quote --- First here is the correct terminology Soldering* is a process under a temperature of 840'F (450'C) (soft solder) Silver soldering,silfoss and hard soldering are not soldering but non preferred names or descriptors of Brazing Filler rod melts above 840'F (450'C) Brazing* is a process above a temperature of 840'F (450'C) Both Soldering and brazing depend on capillary actions to draw the filler metal into the joint. Welding* is a process that depends on the melting of the base and filler metals to form the joint. It doesn't depend on capillary in any way. Braze welding is not a brazing process as it is above the temp. of brazing and lower than welding. Most frequently repairing cast iron parts. You are welding with brazing filler rod On using the propane type aluminum solder, Two important things you have to do yes one of them is practice, and the second is using only a stainless steel wire brush used for only aluminum! No ferrous contamination, of the weld area. Along with the stainless pick or fork to move the oxides of the top of the solder pool. The oxides form as soon as you as you stop cleaning the surface and have to be moved out of the way. I have used the aluminum in reality it is a white metal solder for years, as it will work on some die cast too. Cleanliness is of the up most. Here is the instruction sheet that comes with the type that is demoed and sold at car and model engineering shows in this area I know the guy that sells it for 15 years. He has been a staple at the NAMES expo for years. In addition Probably easier for Our English members to find. Is a wonderful book by Cassell out of London. by Eric Franklin called Soldering,Brazing and Welding second edition 1963 it predateds both of the book id numbering systems! I haven't finished a review to post yet but it is a great book on the subjects of the title and more. It covers everything, in the soldering area, both hard and soft explains the differences in the processes. wiping lead joints on pipes. Covers the repair and operation of irons ,blow pipes and other apparatus. Welding oxy/fuel,electrically and by forge. It is a great book if and when you can find it. Back to the subject of the solder, and it is solder not a brazing filler rod! no matter what they call it. I have used the other brand that is sold at the Big box stores with the aluminum flux it never worked as well as the propane only stuff. I have a package of aluminum solder that used to to packaged by Kester brand here in the states. As a historical footnote, Aluminum soldering was kicked to the curb after the war here in the states. As the new and marvelous process Heli-acr came to the fore front. We know now it as TIG since Heli-arc was a brand name of the Hobart company. :coffee: |

Glen, Thanks for all that info. This has become quite an informative thread. I'm wondering if it should be moved to the "Metal Stuff" board where welding is one of the subject matters? Opinions? What got my interest piqued was the two part article in "The Home Shop Machinist" by Kent White. :bugeye: I just realized when I went to check out were I saw this article it's written by the person you mentioned Glen. :bugeye: I guess that's why I wanted to try aluminum wedling/brazing/soldering. His article is very inspiring. :headbang: Bernd |
