Soldering: An Alternative to Brazing In soldering, two metal pieces are joined together using a third metal alloy, often softer with a lower melting point than those being joined. You can use an alloy of lead and tin which we call a soft solder or an alloy of zinc and copper which we call a silver or spelt solder.
Can I solder two pieces of metal together?
But you can join them by melting them together in a process known as welding. The basic idea is simple: you apply a source of heat to melt the two metals so they fuse and form a secure joint.
Can you use solder to join metal?
Metals that can be soldered include gold, silver, copper, brass, and iron. The filler, called solder, melts. When it solidifies, it is bonded to the metal parts and joins them. The bond is not as strong as brazed joint or welded one.
How do you join two pieces of metal together?
One of the most common methods of joining two pieces of metals together is through welding. However, there are several alternatives to welding methods that can be used to do this. It is possible to join metal pieces by methods like riveting, soldering, bolting or brazing.
Related Question Can you solder 2 pieces of metal together?
What do I need to solder metal together?
Is soldering as strong as welding?
Different metals can be soldered: Metals that can be soldered include gold, silver, copper, brass, and iron. The bond created when the melted soldered material solidifies. Not as strong as welding or brazing. A soldered bond is not as strong as a welded or brazed one because it is not a mechanical connection.
Do I need flux to solder?
Yes, solder can be used without flux. To do so, you will need something other than flux to break down the oxides on the metal surface, without which your surface may be damaged or not properly cleaned.
Can I use a soldering iron to weld metal?
Suitable for joining copper, brass and many ferrous metals, including galvanized sheet metal, soldering is most often done with an electric soldering iron or soldering gun.
Can you superglue metal to metal?
Super glue is an ideal choice for gluing metal to metal, or to other materials. Be sure to keep metal surfaces clean and use a clamp to keep parts fitting snugly while setting. Many broken metal items can be salvaged and repaired using super glue.
How do you join metal to metal?
Another option for gluing metal is Loctite Epoxy Weld Bonding Compound. A convenient alternative to welding, it's the strongest solution for bonding most metals, including iron, steel, aluminum, brass, copper, and pewter.
How do you solder two flat pieces of metal together?
Why does my solder not stick?
A classic reason solder won't stick to something is because you're not getting it hot enough. My interns come to me with this problem all the time. Make sure the tip of the iron is nice and shiny. Touch some solder on it, and it should melt almost instantly.
Does solder stick to steel?
Now you can solder steel to pot metal at 350 degrees using a propane torch and Super Alloy 1 multi-metal solder rod and flux. To solder steel to pot metal, begin by removing all oxidation from both parts. This can be achieved using any type of abrasive material: sandpaper, Dremel tool, wire brush etc.
Can you solder to zinc?
Zinc has a relatively low melting point and therefore is not ideal but still can be soldered. Lead coated copper should be soldered with 60/40 lead tin solder.
How do you solder wire to metal?
Your first task is to strip a small section at the end of the wire. Then twist the stands together. Then heat the end of the wire with the soldering iron and apply solder so that it flows into the twisted stands. At this point you may want to trim the tinned end of the wire a little if it is too long.
What is stronger than soldering?
Brazing joints are weaker than welding joints but stronger than soldering joints. This can be used to bear the load up to some extent.
Can you braze with a propane torch?
Brazing permanently joins two metals using a torch. You can use a propane torch to braze most metals you want to join. Propane torches are widely available in your local hardware stores, plumbing supply houses as well as at metalsmith and jewelry supply companies.
What is the difference between soldering and crimping?
Crimping tools are designed to create an air-tight seal between the cable and the connector. Soldering uses heated metal to join the cable to the connector. Over time, this filler metal will degrade, which may cause the connection to fail.

What is the best adhesive for bonding metal to metal?
Epoxy glues form the strongest metal-to-metal bonds. Most epoxy products instruct you to mix equal parts of adhesive and hardener and apply the mixed material with an appropriate tool to one of the surfaces you are bonding.
Does Gorilla Glue work on metal to metal?
The best glue to use on metal doesn't have a straightforward answer. Polyurethane based glues (like Gorilla Glue) and cyanoacrylate based adhesives (like Gorilla Super Glue) will both work on metals, as will epoxies and contact adhesive; which glue is best depends on a few other considerations.
What is the strongest adhesive for metal?
Epoxy adhesives form the strongest metal-to-metal bonds. They consist of two parts – the adhesive and the hardener. These combine to create strong, long-lasting bonds between different types of metal or between metal and concrete surfaces. For metal you may want to find yourself a two-part epoxy adhesive.
How do you fix a hole in metal without welding?
Epoxy or Tape
Epoxy and tape are two common no-weld hole repair options. These do-it-yourself approaches are effective when repairing a small hole rather than a significant tear. Specialty epoxy and tape products are designed to patch steel and metal.
