Fusion welding is a crucial and widely used procedure in the manufacturing of metals. However, you could occasionally have trouble embracing welding and wish there were other ways to link metal materials without welding.
So, how to join two pieces of metal without welding? There are a plethora of methods that offer alternatives to welding, even though these operations/techniques demand skill and equipment.
Not all of us have access to a welder machine, so learning how to join two pieces of metal without welding might be useful. Knowing other approaches to get the same result is useful since they might take less time and money. Let’s be more specific here.
How To Join Two Pieces Of Metal Without Welding?
In order to unite two metals, we may frequently need to use a technique other than welding. There are many possible causes, and the following list of typical causes will assist us in selecting the kind of metal joining technique:
- Due to metallurgical incompatibility, fusion welding is impractical or does not result in a strong junction for some metals (combination such as aluminum and copper or aluminum and steel).
- There are some metals that are difficult to weld, and attempting to do so runs the risk of creating cracks, having the metal react with the environment, losing its qualities, etc.
- It’s not necessary to weld every point in a metal construction. A brazed connection may be suitable for many joints that operate at modest loads and temperatures.
- It would be best if you occasionally had connections that you can take apart and reassemble as needed. Mechanical fasteners can be used to create such joins.
- Riveting is a neater and more aesthetically pleasing method of joining than welding for projects like creating a passenger vehicle or bus body.
There are different ways of joining metal without utilizing welding. All of them are reasonably priced and offer highly durable and incredibly strong joints. The most frequently used techniques regarding “how to join two pieces of metal without welding” are listed below.
Two pieces of heavy metal are joined together by riveting. It could be utilized to join parts of tankers, wagons, boilers, bridges, etc. The four different types of riveting are chain riveting, zigzag riveting, single riveting, and double riveting.
- The plates must have drilled or punched holes if you’re utilizing light gauge panels.
- Every drilling operation should leave a burr.
- The metal components must be tightly fastened together.
- One rivet is inserted into each hole.
- Hit the rivet firmly after insertion to ensure that its tip is straight.
- Allow the parts to cool so that the rivets can bring them together tightly.
Electronics, circuit boards, and other products are frequently made using soldering, a procedure that is comparable to welding. This method and welding vary primarily due to the latter calling for the creation of a mechanical linkage.
The metals we are connecting must have an electric link in order to solder. The primary component of the soldering process is solder. This adds to the necessary electric connection and is often constructed entirely of tin, making it relatively simple to melt.
The solder may contain different metals besides tin, such as zinc, silver, and copper. It doesn’t necessitate as much heat energy as welding because the soldering metals at a low temperature.
- Turn on the iron and allow it some time to warm up. The metal ends where you need to attach them should be sanded down as it heals. In order for the components to fit together without gaps, the ground should be as seamless as possible.
- Clean the surface first, and then seal any sections with painter’s tape that you do not intend to solder. On the areas where the solder weld will go, apply flux.
- When setting up your workspace, keep a bit of space between the soldier and you at all times.
- Put your protective eyewear and, if necessary, also wear gloves.
- Commence the soldering procedure
- Afterward, allow the metal to cool.
- Once it has all cooled, scrape off the remaining solder.
Using a kind of filler material to join two metal components together is known as brazing. The filler metal heats up at a heat temperature of more than 800 degrees. While similar to welding, this technique is less expensive.
Additionally, utilizing an adhesive as opposed to burning the metal parts themselves is more like doing it. For this purpose, we continue to regard it as a technique for joining metals without welding.
- The two metals must be clearly connected for capillary action to be effective.
- For good brazing, both metal surfaces must be thoroughly clean. Consequently, clean any remaining rust, after removing any oil and grease.
- Before brazing, apply the chemical flux to the joint surfaces to prevent the formation of oxides.
- If the pieces’ forms allow it, use gravity to hold them in the proper brazing position.
- Place the filler material in the joint after first heating the component to the brazing temperature.
- After brazing, wipe the assembly because most fluxes may be toxic. This includes removing any oxide scale and flux residue.

Using glue to connect two material pieces together is the easiest method. Almost anyone can apply glue to a few surfaces and quickly join them. The type and strength of the glue, applying pressure to the metals while the glue dries, and other factors are all at play in this situation.
Note: Prior to using its process, try to adhere to the following instruction.
The glue-applying surfaces must be clean, dry, and ideally a touch rough. Remove all oil, grease, wax, grime, and dust. Clean off fingerprints using a rag as well. Consider using some sandpaper to lightly rub them up if the ground of the metal is too smooth.
Read the clear instructions on the glue tube. You will learn about the proper application techniques and the necessary drying time from this. Implement the glue, including both surfaces, by opening the cap and using a spatula or brush.
While superglue may need one drop applied to every square inch, epoxy glue may require substantial mixing. Place the two metal pieces in place and tightly push them together. No gaps should exist between the sections.
Squeeze them for a little while, and then leave them alone for however long the directions specify. Remember that metallic epoxies typically require clamping for sixty minutes or so. In comparison to polyurethanes and superglues, they have longer cure times.
If you require a solid bond, the clamp is still advised for the latter. Let the glued components alone for the entire night to ensure a strong bond. In order to know more about “how to join two pieces of metal without welding?” continue reading this blog article.
- Be sure to work in a garage (workshop) or another space with adequate ventilation. Additionally, there must be adequate room to store and manage whatever you require.
- Lay down extra newspaper or covering materials, and carefully drape any furniture in the area.
- Next, pay special attention to the components that need to be bonded together. Test their compatibility to ensure a perfect match.
- Dust, fabric slivers, and leftover adhesive should all be removed from the areas where glue will be applied.
- Additionally, be cautious about putting on nitrile or latex-based protective gloves. Further, you cannot use cotton, PVC, or nylon because you are using metal adhesive.
A spot is a popular alternative to a welder when joining many steel plates. This method combines the utilization of electric current, pressure, and heat. Alternative terminology for this method is resistance welding.
Spot welding is mechanically quite straightforward. The two copper metallic electrodes are utilized for welding the metal plates together without using a filler material usually used in traditional welding.
Electric current passing into electrodes causes metal plates to melt into a uniform, smooth piece. The automotive industry is one that uses spot/resistance welding most frequently. Industrial robotics is a different sector that regularly uses spot welding methods.
- By putting them together or aligning them, the steel sheets are ready for welding. This is based on the understanding that the welder has already been assembled, is attached, and is prepared for operation.
- Make doubly sure the tweezers and wires are properly positioned as well. Use the fine focus to position the electrode appropriately. The next important step involves putting on some welding safety glasses and hand protection.
- Additionally, the two copper and metal sheets need to be secured with clamps and put next to the wires that are held in place by vise-grip tongs. Once the swollen joint has been lined up with the wires/electrodes, firmly grasp the tweezers on your right wrist.
- To guarantee that the tweezers keep in touch with the weld zone, exert force on the handle with your left hand. Turn on the light and continue to hold down the tongs for up to five seconds.
- Unplug the switch and then take out the metal/steel sheet you previously welded. Cool the metal sheet down before using it.
When joining two or more metal components with hardware, two pieces or more pieces of sheet metal that are overlapped typically have predrilled holes or drilled through them that enable the hardware to link the two parts.
To mention some of these sorts of hardware, there are nuts, screws, and bolts. The advantages of employing hardware include affordability, ease of repair, and the fact that it isn’t permanently like welding.
Note: The fact that hardware assembly is not as sturdy as welding is its only drawback.
- Make the hardware needed to assemble the metal components. Declutter the area where you work.
- Make a hole in the two pieces or more metal components using the right drill bit.
- Now you should insert the bolt/nut into the metal piece’s hole. On the other end, a nut of the proper size can be tightened.
- What kind and what shape of nuts/bolts you require will depend on your project. However, this amazing package is a fantastic choice for small to medium-sized activities.
- Along with various-sized nuts/bolts, the bundle includes hex wrenches and screws.

How To Join Two Steel Pipes Without Welding?
The most typical type of pipe used in water distribution systems is steel. Additionally, they are utilized in sewage systems and natural gas pipes. These experience enormous strain and stress, which results in crackdowns. The following are the main types of glue that can help you in joining steel pipes.
Steel and polyurethanes are frequently used together. Polyurethanes dry rapidly without becoming brittle and are UV and water-resistant. They can be painted, stained, and sanded after they have dried. They are, therefore, excellent for various household tasks, such as fixing flooring or finishing woodwork like cupboards or tables.
To form stronger bonding than common construction glue, a high-quality exterior building glue should be a polyurethane or moisture-curing glue. It is the ideal metal adhesive for outdoor applications because, like so many polyurethanes, it adheres to metal over a wide temperature range.
Slightly elevated epoxy adhesives are frequently used in woodworking and carpentry and for specialty creative applications like costume jewelry manufacturing. These procedures sometimes use metal in addition to wood, such as for table legs, door knobs, or railings.
Epoxies can be flexible or rigid, clear or opaque, and have a quick or gradual setting time. Additionally, they offer excellent heat and chemical resistance. The finest epoxy for steel is the two components of Concrete/Loctite Epoxy Metal, which consists of an epoxy glue and a bonding agent.
All steel and cement surfaces can be repaired, filled in with, and rebuilt using the resin and adhesive combination to provide a long-lasting, elevated bond that hardens in a matter of minutes.
Super glues are industrial adhesives with great performance that are ideal for practically all residential repairs. Most adhesives work well with metal, textiles, woodwork, and plastics, making them handy for attaching or fixing automotive parts, decorations, small appliances, and numerous other everyday goods.
“Loctite Super Glue Liquid” is dependable and quick for a superior bind between metals. Strong and easy to apply, it sets quickly, doesn’t need clamping, and spreads easily. It is also resistant to weather and moisture.
