Welding helmet: What is it for? |
Posted: April 21, 2021 |
Welded work can directly reach the eyes and face. The weld releases radiation, which also causes burns on other parts of the body. Welding activities are extremely important. To maintain the safety and physical integrity of the welders, it is necessary to use protective equipment. Welding is the process of mechanically joining metallic materials and happens by heating the parts to come together. Magnetic waves are emitted when the welding is carried out by a heated electric arc. There is also welding by combustion heating systems with different gases. These processes give off hot sparks in the air, which generate many health risks. If you want to find out details on welding helmet, you have to browse around Helmetsadvisor site. In this post we will talk about the Welding Helmet and what it is for. This equipment is one among others that must be used during welding. Read and learn more about this important PPE. WeldingAs previously described, welding is the joining of metals or non-metals by heating. The welding process can be carried out by pressure or by fusion. Pressure weldingDeformation of surfaces in contact by breaking layers, bringing them together by chemical bonding. Being that in the pressure welding process you can use ultrasound or friction, electrical resistance, explosion, among others. Fusion weldingFusion welding is the local heating of the region to be welded, until the union solidifies the material. Fusion welding also includes MIG / MAG welding. MIG / MAG weldingMIG / MAG (Metal Inert Gas / Metal Active Gas) welding is the most used in the metallurgical industries, as it welds steel, aluminum, stainless steel, copper etc. It involves transferring the filler metal to the melt pool. Helmet for the professional welderThe welder helmet protects the face, eyes, front of the neck and the ear from radiation derived from welding both from gas and electric arc processes. There are risks to the welder due to non-ionizing radiation, such as metal fumes, accidents common to other types of work and others. In the long run, these risks can become worse, becoming lung diseases, skin diseases, eye problems, etc. For this reason, the Welding Helmet is an individual protection equipment that serves to protect welders from the immediate risk of suffering accidents with the projection of hot sparks on the face, radiation etc. Components of the welder helmetSuspensionIt is an element of the helmet whose function is to fix it to the head, formed by the cap and adjustable crown. The material must be resistant, non-toxic and must not deform. It must contain a rotating ratchet. Helmet bodyIt is the part that preserves the face of the welder from flames, radiation, etc. The helmets made of Celeron have a rectangular viewfinder and the lens is colorless, with a light filter so that the radiation does not reach the eyes. LensLenses without automatic dimming - are also known as passive lenses. They are of darkened glass and fixed tint. This is the simplest form of helmet lens for a welder and for a long time only it existed. Auto darkening lens - is a component of the Auto Welding Helmet. This lens is clear and only darkens instantly only when the welding arc is triggered. It is better than the non-automatic lens because it provides greater precision and quality during welding. The 3M Speedglas Welding Helmet is an equipment that increases the protection of the welder and the quality of the weld. To perform welding activities safely, always remember the importance of using the Welding Helmet. In addition to protective equipment, the welder must carry out various tests to check his health.
