Welding Guidelines and Factors

welding is an important process in fabricating various materials where two or more metal types are combined by way of the melting and cooling down processes. This is not an easy process, and it needs a skilled worker to perform this job. One also has to be extra careful when doing this particular engineering process. Welding can be performed using a laser, gas flame, ultrasound, friction, electric beam and electric arc either in an open space, in the outer space, or under the water. No matter where welding is performed, this still is hazardous. Without exercising precautionary measures, you may obtain burns, may experience electric shock, or may be exposed to UV rays and toxic fumes. Here are some precautionary measures that you have to keep in mind when welding: 1. Since welding involves heat, it is a must that you remove all porous and flammable things that are near the area where you will weld. 2. Welding must be performed in a well ventilated space to prevent you from exhaling harmful chemicals or toxics that are emitted by the soldering machine. 3. You must have a fire extinguisher that is always on stand-by. Make sure that its not expired and that it is in good working condition. 4. You must have a deep knowledge about welding. Performing this job with a little knowledge is very dangerous. In case you are in the process of learning how to solder, you must see to it that there is someone, who is well-versed with the job, is assisting you. 5. No other parts must be present near the welding area except for the metal that youll be joining together. 6. When welding, wear clothing that made of wool rather than of cotton because cotton can easily get burned. Better yet, wear a jacket that is fireproof just to be safer. Different Factors Involved in welding 1. Welding Current. This refers to the amount of current or electric power utilized in welding. It can be determined through the use of an ammeter or a power source meter. 2. Wire Electrode. This is also known as stick-out. This pertains to the gap between the wire electrodes end and the tips of the electrical contact. 3. Speed of Arc Travel. This refers to the speed at which the arc travels on the metals that are being joined together.
