What Is Resistance Soldering? What Tools Are Used For The Job?

Now, everybody is aware of the traditional method of soldering, you know that soldering needs electricity as well as heat so as to melt a soft metallic alloy in order to produce a tougher metal joint. On the other hand, do you know that there’s another form of soldering which is known as resistance soldering?

In this article, you are going to know about all the things in regards with this form of soldering and we will also do the comparison in between resistance soldering and traditional soldering methods.

You must be already aware about what a traditional soldering is all about as well as the accessories you will require for the soldering process i.e. a soft metal alloy. Such a metal could be a flux based or even lead based and could be bought from anywhere, where such soldering equipments are sold and also from majority of hardware stores.

You must be aware of the fact that it’s the traditional form of soldering which is mostly utilized on circuit boards such as the one which is present in your TV, computer, DVD player & even inside your toaster.

There’s no other forms of soldering which can be utilized onto the circuit boards and even with the conventional form of soldering that has been used on such type of boards since a long time, you must to be very cautious.

The reason for this is because, if you leave the iron onto the metallic joint for too long, you are likely to run into the possibilities of melting the inner parts of one or more of your constituents which means that you’ll require the soldering joint to become as tough as possible.

You must also ensure that your soldering joint isn’t too old as with age such a piece of metal is likely to become more resistant and harder to heat since it has heat running above it all the time.

Because of this, you’ll be required to substitute that joint again and again.

Now let’s see what is this form of soldering that we are talking about in this article & whether it can be used onto the circuit boards?

Soldering Circuits Boards is not Always a Cakewalk !

Resistance soldering is such a form of soldering which does not need you to plug your equipment to a wall plug. The initial thing which you’ll want to understand is that it’s powered with the help of batteries.

This means that if it utilizes heat, the heat wouldn’t be adequate enough for melting even the weakest alloy metal such as soldering metal.

Resistance soldering transfers an electric current through the joint which must be melted or the wire which must be bound. The charge which is transferred through tends to heat up the material which is used & in return that heat would melt whatever you’re trying to melt.

Tools used for a resistance soldering job are,

  • A specialized step-down transformer that will generate the appropriate current
  • A resistive material to generate the heat
  • Ability to complete an electrical circuit

As a result, you can’t use this mini tool on your circuit board as the charge is likely to blow out one or even more of your constituents, however it is really a great equipment to use in the plumbing business as it is very portable & doesn’t use any type of cords & no socket in electricity is utilized either.

The cost of the this kind of a tool is normally higher as compared to the conventional soldering.

An usual resistance soldering job is carried out at a rather complex station in comparison to the portable and simpler conventional type of soldering using an iron.
