Welding is a molten metal joining two pieces of metal, in the same way that performs the operation of melting an alloy to join two metals but different from when two pieces of metal welded to join together to form a welded joint. The
industry of electronic The alloy of tin and lead is most often used, but other alloys , this combination gives the best results. The mixture of these two elements creates an uncommon event. Each element has a high melting point, but when mixed produce an alloy with a lower melting point than any of the items for this we must learn the basics for welding. Without this knowledge is difficult to envision that occurs when making a solder joint and the effects of the different parts of the process.

Welding Theory

Before making a union, it is necessary that the solder "wet" base metals or base metals to form the union. This is the most important factor when welding. When welding intermolecular bond is formed between the solder and metal. Welding molecules penetrate the structure base metal to form a solid extructura, totalmemte metal.

are commonly used in electronic power welders reduced, since generally it is delicate work. In plumbing, however, are used to weld pipe welders more power and lamps, and other welding systems.
It is a tool that has enormous scope, either for new assemblies or for repair. The welder must allow soldering operations for the union of two or more drivers, or drivers with items of equipment. Due to their frequent use, the welder must produce, among other features, great reliability and durability.
In general, it is a mass of copper (tip), which is heated indirectly by an electric heater connected to an electrical outlet (usually 220v outlet). The types that are usually found in the market can be classified into common welding or "pen" and soldering gun.

Types of welders

This is the classic type welder pencil 30w. Its warming is permanent and has a high thermal inertia. Both at the time of the weld and in the pauses of this work, the welder stays connected to the mains. It is appropriate for repetitive and numerous.

The soldering gun. The tip is heated by the effect of a large current through it (the bulky handle carries in a transformer that produces it). Useful for odd jobs and instantly warming. Not widely used in electronics because the tip is often not fine enough and accurate.

Media Types

Since the welder keeps the tip hot (about 250 ~ 300 º C), it is necessary to use a support which leave for time is not used, to avoid burning the work table. Here are some examples:

1. Support typical for light-duty welders. It has sponge.
2. JBC support that allows you to place the iron in two different ways. Has
sponge.
3. Support easier. Can constructed with a piece of sheet metal and a wooden table
.
4. Welder with all the points that can be fitted: fine point tip
thick, puna desoldering integrated circuits and even accessory
