Those who see and fuck a lot cannot avoid welding from time to time. Most do-it-yourselfers were involved in welding at least once. But welding is not just welding. What types of welding are there, which are suitable and when is welding carried out?
What exactly is welding?Welding describes a production process in which different parts are bonded as inseparably as possible when exposed to heat. Traditionally, metals are connected to one another by so-called flame welding. Here, the workpiece is heated in a forge fire by putting air aside until it melts, and then connected with a strong punch under the forging hammer. However, this type of welding is mainly found on the craft market today, now there are more modern welding methods.
What should beginners pay attention to?As a beginner in the field of welding, you don't have to start with luck, you first have to manage the various welding processes and, above all, take the necessary safety precautions. Sparks are the rule rather than the exception when welding, and the welding environment should therefore also be adjusted accordingly.
What type of solder is there?There are many types of welding. The best method depends on various influencing factors and the material used. When carrying out welding work, ensure that you have suitable protective equipment to minimize the risk to life and limb. First of all, a fundamental distinction was made between so-called fusion welding and pressure welding.
fusion weldingIn fusion welding or fusion welding, metals of the same quality are melted at the connection point and then joined together with or without the addition of filler material. You can find out more about fusion welding at the following link.
Pressure welding processPressure welding or pressure welding connects the workpieces to one another at the connection point without additions by compression, which means that force is required to connect the workpieces.
There are also a number of welding techniques that are more or less suitable for certain individual cases depending on the material and project. The most common are:
Electrode welding: Electronic welding is the most common in most DIY workshops. This is also known as arc welding because arcs occur between the electrodes due to a short circuit. The equipment is affordable and the technology is easy to learn. Electronic welding can be used for many different tasks. However, structural components and thin sheets should not be combined with this technique.
Inert gas welding, MIG / MAG welding: Inert gas welding mainly takes place when thin sheets, pipes or rods are being assembled. The equipment required is slightly larger than that of electronic welding, and gas (shielding gas) is also required. Inert gas is used in the MIG process and active gas in the MAG welding. Inert gas welding should not be carried out by inexperienced people without instructions, but should be handed over to a specialist in case of doubt.
Spot welding: Spot welding is mainly used in vehicle construction and sheet metal processing. This allows the seams to join and thus ensure good adhesion. Spot welding methods can also be used to join non-weldable materials. However, this is not suitable for processing aluminum.
Stud welding: This method is relatively common in practice, although it is not very well known. A special stud welding machine is required, which welds pins, studs and sockets with arcs to metal surfaces. Then the parts are inserted into each other and the pins / bolts and rings are connected with nuts or split pins.
Working technique is a question of practiceAs with all manual work, the handling of welding equipment must be examined. Depending on the welding technology and the specific requirements, various factors play a role: Handling electrodes, welding beads and parts requires experience until the results are satisfactory. You need to try out different techniques and get a little familiar with the device before starting a real project. A few hours of training under the guidance of a welding instructor or even a visit to a welding training center are clearly an advantage.
Electronic welding is suitable for beginners
Beginners should solve this problem by electrowelding and take the first step in the field of composite materials. With suitable protective equipment, electronic welding machines are available at very reasonable prices. They can be used for many welding jobs around the house and yard. Over time, you can dare to use other welding techniques if necessary. Especially when welding, you should not underestimate your own abilities. Parts that carry the load, drop welding and overhead welding should be left to the experts. Depending on the composition and requirements of the metal, specialists can choose from a variety of different welding processes.
