In the market there are different types of welding tools depending on the type of work or welding to be performed. Therefore, in this post we advise you on what tools you need for each type of welding.

1. Welding for electronics:

From the assembly or replacement of electronic components or printed plates, to the wiring of electrical appliances. In electronics, the most used system to guarantee the circulation of current between the different components of a circuit is the soldering with tin or alloys of this, according to the application. 

Very reliable and definitive joints are achieved that allow the electronic components to be held in position and withstand shocks and vibrations quite well, thus ensuring the electrical connection for a long time. 

  • Welder:  The main tool for this type of welding is the manual soldering iron or soldering iron. They can be pencil or gun type . The size or shape of the tip vary depending on the model of the welder and the use that will be made of it. There are tips with special shapes to access difficult areas, however straight models with sharp points are used for almost all applications. The power of the welder depends, above all, on the amount of heat needed to perform the welding and the area to be welded. 
  • Tin:  It is the fundamental component to realize the union . It is usually presented in the form of reels, of different thicknesses and quantities. To ensure proper welding it is necessary that both the tin and the element to be welded reach an appropriate temperature. If that temperature is not reached, or an attempt is made to accelerate the cooling process, the phenomenon called cold welding occurs. It is a poorly made weld, which has no electrical conductivity and that, although joining the components, will sooner or later fail. 
  • Stripper:  To perform a good weld, in addition to the welder and the described alloy, an additional substance, called stripper, is needed. Its mission is to facilitate the uniform distribution of the tin on the surfaces to be joined and avoiding, at the same time, the oxidation produced by the too high temperature of the welder.

2. Flame welding: 

The gas welding was one of the first welding processes developed proved applicable to a variety of materials. For years it was the most used method for welding non-ferrous metals. This type of soldier is usually used for welding doors, soft or metal cutting. The main tools are: 

  • The torch:  There are autonomous or directly connected to a small gas cylinder, and torches that connect to a larger cylinder, through a gas hose. Depending on the type of torch, welding work can be carried out on small pieces of jewelry, as well as copper pipes. 

 

  • Contribution material: To  the flame coming from the torch, and after having heated the materials, a contribution material (usually steel or zinc, tin, copper or bronze alloys) is added which allows an alloy bond with the surface to Weld.
  • Stripper:  As with electronic welding, we also need a stripper, in this case a powder stripper is usually used , or already placed in a crust in the same welding rods. That stripper will understand oxidation-free welding and will help a better grip. 

3. Electric welding:

The most suitable for welding ferrous materials . Within electric welding, we find different types of welding or welding systems, depending on the type of joint, the type of material of contribution or the existence or not of gases in the welding process. The types of electric welding are:

  • Electrode or MMA welding:  Suitable for joining ferrous materials with thicknesses between 1mm and 1cm thick. Knowing that the smaller the thickness of the material to be welded, the harder it will be to achieve welding and the easier we will have to melt or bore the sheet to be welded. What is necessary for this type of welding would be an arc welding group or inverter. The electrodes, of the appropriate diameter to the thickness of the metal to be welded, and a shield or protective shield. These screens come with a darkened glass, which prevents the damage that the bright flash produced by the welding would cause in our eyes.
  • TIG welding:  For this type of welding we can use a TIG welding group or an inverter with a special clamp for this type of welding. It is a weld that needs the presence of a gas, usually argon or CO 2.  We would also need, apart from the TIG group or the clamp, a mask or screen to weld and some rods to provide material. Welds made with the TIG system are stronger and resistant to corrosion than made with conventional electrodes. When high quality and better finishes are needed, it is necessary to use the TIG system to achieve homogeneous, good-looking and completely smooth welds.
  • MIG / MAG wire welding: In this case, the welding equipment carries a spool of thread that serves as input material. A small motor is responsible for spinning the spool and providing a constant flow of thread to the nozzle each time we press the gun trigger. In case of using gas, we also activate or stop its output from the trigger. From the front panel we can select both the thread exit speed and the tension, depending on the thickness of the material to be welded. It is a weld suitable for thin materials or to achieve better finishes than with electrode welding. With the TIG welding we can weld in any position, thicknesses from 0.7 mm to about 6 mm, with a good finish, and being able to deposit more metal without damaging the quality of the welding.
