This is a technique brought to our shop by a retired Navy Chief about 20 years ago. We were repairing large sheet metal outer cases for hot gas expanders - complex structures that underwent thermal cycling , sometime several times a day. These cases would crack along the HAZ from previous weld repair attempts. These weldments were about 30 years old and had undergone may different and unsuccessful weld repair methods by "experts" in the welding and metallurgy fields. Thanks to Chief Beckham!
All welders make this stuff look so easy. I'm trying to do a simple bronze to bronze weld (2 small pipes) using HHO cooled with MAP gas. The bronze pipes are 1/4" thick but soon as it gets hot enough to melt I feed the bronze rod then it collapses, drips or distorts. When I weld steel I never have this issue. But something about bronze .. it's like the second the surface of the pipes & rod melt I push the rod then realize the whole back melted out. There's gotta be a better way to stop thin metals from collapsing when you need a weld as opposed to a braze. I known an arc would be ideal but the whole reason I built my HHO is to practice working with gases.
+Robert Cece Thanks for watching the video and for your question. Can you please direct this question with more detail to our "Ask The Experts" section of our website? We will be happy to help you the best we can. Here is the link: www.lincolnelectric.com/en-us/support/ask-the-experts/Pages/ask-the-experts.aspx
+oldcarsgarage You can use any DC classified Tungsten Electrode. We are working in DC- and the alloy we are using is silicon bronze (ERCUSI). There are other copper alloys but that is what we used. Thanks for the question!!
this type of weld can be very strong but you need lots of filler material then :-) I have a plate cutter welded with copper, very strong, long time ago they did a lot with copper welding.

WOW. The only guy in a Lincoln video who can actually weld...
Hey Lincoln, more of this guy please ~ he's great...
Thanks for a great video. That is very helpful as I am trying to add the copper color to a metal sculpture. This was just what I needed.
wow. very cool for home use, great info, great presenter. thanks for this video!
Great demo!
Awesome video!
We want MORE videos!!!!!

that tungsten electrode you use for welding ?? you work in AC or DC ?? which the brass rod specification ?? thank you!!

i thought i new everything.....thank uuu....
great
or very good fitting welding surfaces then it is maybe stronger then welding
please improve your welding camera filming. can not see how do you do .... distances... pudle....
thank you again
