These pics come from a new aerospace test facility that they are constructing at the University of Notre Dame. The SSF-6 is working great.
I am attempting to make all of these fittings air tight as they are used for pressure measurements. We can¹t have any leaks. I had very little warpage of my base metal and I think this is really going to work out very well.

Steel is an alloy composed of iron and carbon—the higher the carbon content, the stronger, harder and more brittle the steel. There are many types of steel that can be used for steel welding jobs, all of which are categorized based upon various physical properties and carbon content. High carbon steel is very strong and it is used for files, cold chisels and various metal tools while low carbon steel is used for tubing, nails and castings.
Before you start welding steel, you will have to first determine the weldability of the metal. This is inversely proportional to its ability to be hardened by heat. Basically, this means that varieties of the metal with fewer alloying agents can easily be welded better than others.
Next, measure the equivalent carbon content of the different alloys of steel. This compares the properties of any steel alloy to those found in ordinary carbon steel. If possible, use only high strength, low-alloy metals specifically designed for welding steel.
Most jobs require only a hand held propane torch. Super Alloy 1 is recommended when heat or aesthetics is an issue. Otherwise we recommend our SSF-6 Silver Solder for torch welding: with a holding strength of 71,000 PSI, SSF-6 is as strong as a MIG or TIG weld, with a beautiful finish.
Steel repair on stainless steel can be very difficult; it is difficult to cut and is prone to distortion because of its high thermal expansion. Control the amount of ferrite in the weld to minimize hot cracking, preheat, and use steel welding and solder products such as Super Alloy 1, SSF-6, and SSQ-6 when working on different types of stainless steel.

Square steel is joined to rectangular steel with SSF-6 and an oxyacetylene torch. SSF-6 provides a perfect color match and better finish than MIG welding, with a bond of over 70,000 PSI.
At 56% silver, SSF-6 Silver Solder is ideal for brazing all types of steel. This video gives step by step instructions for repairing steel pipe with an oxy-acetylene torch.
Rich Shoop (The Gun Slinger, Mt. Ayr, Indiana) was hired to restore this antique Ithaca, and discovered a missing piece on the barrel.
2 galvanized steel plates are joined using Super Alloy 1 and a propane torch. The low melting point of Super Alloy 1 is ideal for soldering without damaging the protective zinc coating.
Soldering Galvanized Steel with Super Alloy 1
Josh Colson from Auburn Muffler and Auto Repair in Auburn, Washington, is using SSF-6 Silver Solder by MuggyWeld.com, to braze a cast iron flange to aluminized steel tubing for better air flow.
SSF-6 brazes a stainless steel tube to a steel plate at over 70,000 PSI with a propane torch.
Joining square steel tubing to mild flat bar steel with SSF-6 Silver Solder. Straight propane is used for this braze, as SSF-6 is lower temperature than most high content silver solders.
SSF-6 Silver Solder brazes stainless steel to copper, brass, or steel... in any combination, and can be successfully applied using a propane torch, oxyacetylene, MAPP gas or a natural gas torch.

Auto body panels are very thin nowadays, and mig welding these parts without warpage can be very difficult.
This clip shows a fender being repaired with Super Alloy 1 and COOL BLUE Heat Paste.
SSQ-6 is the perfect solution for jobs like this--parts are balancing, and if a rod were used they could easily be knocked over but the silver solder almost glues them together and acts like a jig when heated.
