Are you often use soldering for bonding electrical connections, plumbing, and metalworks…? Do you aware of specific tools apart from the soldering iron that is widely used in soldering applications, or are you a beginner for soldering. Well, let’s discuss different soldering applications and conventional tools that make your soldering process much easier and smoother than before.


Metals may be joined by mechanical means (bolting, riveting, etc.) or by welding brazing, soldering, or adhesive bonding. Out of these, Soldering is a process of joining metals by flowing a low melting point alloy termed ‘solder’, between the surfaces that are to be joined.  It is essentially an alloying process in which certain elements in the solder combine with the metals of the joint, and this is only possible if clean metal and clean molten solder are brought into effective contact.

The basic equipment required for normal soldering operations is a ‘Soldering iron’ of a suitable type and a source of heat (these may be combined, as in the electric soldering iron), solder of the correct composition for the job in hand, and a suitable flux-more elaborate equipment is needed for such special applications of the process as sweating and dip soldering, but these types of soldering are not usually encountered in the general workshop. Let’s discuss briefly soldering types widely used.

Following are the general types of soldering applied on different temperature levels.

  • Soft Soldering– General type of soldering used for joining wires and small components. The joining parts of soft soldering are not exposed to higher temperatures (normally ranging between 90-450 degrees) and are not subjected to higher loads and forces. The solder type used in this process has a melting point ranging between 150-350 degrees and is commonly lead or tin. Zinc chloride is the common soldering flux used in soft soldering.
  • Hard Soldering– This type uses a solder that is higher temperature and stronger than those used in soft soldering. This type is also known as silver soldering where silver mixed with tin is utilized as a solder in the process. Brass is also used as a solder for this type and to strengthen the connection a blowtorch is implemented. Normally in this type, solders have a temperature range of 600 – 900 degrees and fluxes are in paste form.
  • Brazing – This type uses metals with a melting point than the above-said soldering types. The process is much similar to hard soldering where the metal being bonded is heated rather than being melted. When both joining metals are heated at a higher temperature the melted solder is placed in between two joining metals.

As solder is used in joining the metals or components in a circuit or metalwork, flux is used to prepare the joining surface to perform the soldering perfectly. It removes any contamination in the metal surface and helps in wetting the molten solder between metals and protects the joints from re-oxidation during soldering.

When performing any of the soldering types described earlier, a proper solder needs to be used. There are some standards to choose the perfect solder type for soldering applications. Some of them are ASTM B579, ASTM B907, ASTM B828 by ASTM international. It is a good practice to adhere to each mentioned standard before you are in to any of the engineering processes.

Proper safety practices need to implement when carrying out a soldering process. The correct type of PPE must be worn to prevent hazards caused by heat. Not only that fumes are released when metals are being heated during the soldering process. So appropriate respirators and goggles, gloves need to use. You can use the following recommended PPE when working on brazing soldering tasks.

Now we have a better understanding of soldering and the types of components used. Let’s discuss the main topic, the conventional tools that are implemented for soldering applications.


The conventional tool types mentioned below are the basic tools that will make your soldering task a perfect one.

  • Soldering Iron
  • Soldering Station (Generally includes conventional Soldering stand, Control unit, and a Sponge)
  • Soldering Iron tips
  • Soldering Hand tools – Scrapers, Tweezers, Holders, Clamps


Soldering iron is the most essential tool used in the soldering process. A soldering iron consists essentially of a copper “bit” secured to a holder, to which is fitted a heat-resistant handle.  The bit varies in weight, according to the nature of the work for which the iron is intended. Normally for the general workshop, bits of 4 ounces are used and adequate for most purposes, but very small bits may be needed for ultra-light soldering in very confined positions.  The bit is the heat reservoir of the tool, and it must be large enough to heat the job adequately.  If you are buying a soldering iron make sure to check the wattage other than the thickness of the tip.  If the iron has a higher wattage, it will heat up quickly and it helps the tip to maintain the higher temperature throughout the process.

The following types of solder iron are available in the market that is customized according to the power, capability, and type of soldering.


Traditional soldering irons are easily available in the market and are used in general soldering activities such as soldering electronic components and household usage. Make sure to look for the wattage when buying a traditional one. Normally for soldering electronic components, ideal power would be 25-40W, 40-60W for household use, and industrial usage such as soldering thick wires, sheet metals 100w is needed.

Most soldering irons come with different types of tips with shapes and sizes. Each tip will provide different applications. Generally, iron tips are divided into two types, the Conical tip, and the Chisel tip. Conical type tips are general tip types that have a pointed cone-like shape. The soldering can be easily carried out from any angle. Other than Conical tips, Chisel tips have a larger surface area which is more likely to transfer heat from the tip to the soldering component. Chisel types are widely used for soldering thick wires.
