Soldering training

Soldering involves very high temperatures, so it is useful to have the right knowledge and skills to make the work effective and, above all, safe. If you plan to work in maintenance or repair, or simply want to be able to use a soldering iron and know how to operate it, it is worth taking part in soldering courses organised by our ERGON Centre for Staff Training. Taking advantage of our training offer is an excellent way to acquire skills that will help you avoid making basic soldering mistakes, such as using the wrong solder, the wrong soldering method, the wrong shape of the joint and the wrong amount of solder, the appearance of air bubbles in the joint, etc.  

Why opt for our training? 

We organise professional soldering courses for both experienced people and those just starting out. We have many years of experience and our instructors are always available and suitably qualified to provide training in the most effective way. Flexibility and the ability to adapt the scope of the courses to the needs of the trainees is also an attribute of our courses. We provide an individual approach and useful tools, accessories and materials. When attending our courses, you will receive a course outline containing the most important information to facilitate the effective absorption of the knowledge acquired in class.  

Scope of training 

The training includes a theoretical part, which is conducted through an electronic platform, and a practical part in the form of workshops, held at one of the branches. In both the theoretical and practical parts, the topics covered include: types of soldering irons and the ways and principles of their use, basic soldering errors, basics of soldering theory, principles of safety and fire protection, practical principles of soldering and cable repair.  

Where can you find us? 

Our branches are located in Warsaw, as well as in other locations throughout Poland. The price is set individually and depends, among other things, on the number of people in the group. Discounts are available for larger organised groups. For more information on cost or schedule, or if you have any other questions, please feel free to contact us by telephone. 

Soldering - basic knowledge

For those involved in the maintenance and repair of various equipment, the ability to solder will be a very useful skill. This is a process used to form an unbreakable bond between metal parts made of different materials by inserting a molten material (solder) with a lower melting point between them. The process involves the penetration of one substance (usually metal) into another using high temperatures to provide mechanical strength. As a result, strong joints are created in products made of steel, glass, cast iron synthetic materials or ceramics. The parts to be soldered, as well as the solder and flux, are brought into contact and heated at a temperature above the melting point of the solder, but below the melting point of the parts to be soldered. Soldering creates a mechanical and electrical contact between the surfaces that can withstand considerable mechanical stresses. Soldering is also a way of joining metals by means of another, more fusible metal. According to modern concepts, the formation of solder compounds takes place in two stages: the formation and development of physical contact and the formation of chemical bonds between the atoms of the contacting surfaces due to the interaction of their electron shells. Depending on the type of parts to be joined and the required strength of the joint, different types of soldering irons are used, as well as different types of solder and flux. In the soldering process itself, we can mention the following several steps: 

  • cleaning - removal of any dirt, grease, coatings and oxides from components, 
  • heating - to temperatures 30 - 50 degrees Celsius higher than the melting of the solder, 
  • forming the joint - mutual diffusion and adhesion, 
  • cooling and cleansing - removal of excess excipients. 

Types of soldering

Depending on the temperature used, we can distinguish between two soldering methods: 

  • soft - is carried out at temperatures below 450 degrees Celsius; it is used to join metals, as well as to repair pipes, seal roofs and gutters, connect electrical cables and electronic circuits; the composition of solder is primarily tin, bismuth, cadmium or antimony, 
  • hard - is carried out when the temperature exceeds 450 degrees Celsius; it is typically used in industrial soldering, as well as in automotive, refrigeration and other industries; mostly silver alloys are used, but also copper-phosphorus, copper and nickel solders.
