Welders

Welding: procedure 

It is possible to distinguish between autogenous and heterogeneous welding, depending on whether filler material is used or not.

To carry out the welding of two parts it is necessary, first of all, to prepare the two edges that you intend to join through an operation called caulking.

Then, the joint is heated until it melts, creating the union of the two joints. 

The temperature that must be reached to achieve fusion varies depending on the process used. Heat, in fact, can be achieved by:

  • Flame, produced by combustion of a gas with air or oxygen;
  • Electric arc, formed between two electrodes;
  • Electrical resistance, obtained by the Joule effect when a current passes through the pieces to be welded;
  • High power laser.

Welders: traditional or inverter

A traditional welder is large in size, this is because it houses a lot of space, while an inverter welder is more flexible, lighter and more compact and, consequently, easier to transport or keep within reach, for example example, in the garage at home.

In terms of operation, the substantial difference between Inverter welders and traditional ones lies in the fact that the former use a particular electronic circuit that generates a current similar to direct current, whereas traditional ones use normal alternating current.

How to choose a welding machine

First of all, you need to take into account your needs, the type of work you intend to carry out and how often you plan to use the machine.

In fact, if the welding machine will be used frequently, a solid and reliable model should be chosen. On the contrary, if it will be used occasionally, then a smaller and cheaper model will be sufficient, still capable of guaranteeing efficient use.

In any case, a good welder must guarantee safety in use and therefore must comply with current regulations.
