MMA (manual metal arc welding) is a very popular method of making welded joints. It is also one of the least complicated and most cost-effective methods of its kind. Welding activities in the field are often carried out using MMA due to the possibility of using mobile equipment. The versatility of MMA is also due to its use in joining e.g. steel, cast iron and, more rarely, non-ferrous metals and their alloys, e.g. copper, nickel, aluminium. What else should you know about welding with this method?    <\/p>\n\n\n\n

MMA basics <\/h2>\n\n\n\n

The MMA welding technique is also known by other names: method 111 and covered electrode welding. The latter name is a reference to the use of a specific accessory in the welding process. This is an electrode made up of a core (a metallic element) and a special coating (a cover mass of various chemical compositions) shielding it. The electrode generates an electric arc between it and the materials to be joined. During this time, under the influence of heat energy at a very high temperature, the lagging melts, releasing gas vapours and slag. Their function is mainly to protect the welded joint from the atmosphere and from the materials solidifying too quickly.   <\/p>\n\n\n\n

MMA vs TIG, MIG, MAG <\/h2>\n\n\n\n

The key difference between MMA and TIG, MIG, MAG methods is the length of the electrode. With MMA, its length is subject to shortening, so that the electrode holder remains at a variable distance from the workpiece. Therefore, one must strive to maintain a constant distance between the weld pool (molten layer of material) and the electrode itself. Such a skill requires both knowledge of things and practical training. If you would like to gain advanced knowledge of welding techniques, come to our UDT training at ERGON.   <\/p>\n\n\n

Safety and security <\/h2>\n\n\n\n

The safety of performing welding work is based on the prevention of burns to the eyes, skin and hair and of fume poisoning, as well as preventing the occurrence of fire. It must be remembered that the electrode arc is not shielded and, therefore, safety measures such as dedicated visors, protective shields and specialised gloves must be implemented. To protect the environment, protective screens can be used and air ventilation control solutions can be implemented.   <\/p>\n\n\n\n

Spawanie MMA (ang. manual metal arc welding) jest bardzo popularn\u0105 metod\u0105 wykonywania po\u0142\u0105cze\u0144 spawanych. Jest tak\u017ce jedn\u0105 z najmniej skomplikowanych, a jednocze\u015bnie najbardziej ekonomicznych metod tego rodzaju. Czynno\u015bci spawania w terenie cz\u0119sto wykonuje si\u0119 technik\u0105 MMA, dzi\u0119ki mo\u017cliwo\u015bci wykorzystania mobilnego sprz\u0119tu. Uniwersalno\u015b\u0107 MMA wynika tak\u017ce z jej zastosowania do \u0142\u0105czenia np. stali, \u017celiwa, a rzadziej tak\u017ce metali nie\u017celaznych i ich stop\u00f3w np. miedzi, niklu, aluminium. Co jeszcze nale\u017cy wiedzie\u0107 o spawaniu t\u0105 metod\u0105?     Podstawy MMA  Technika spawania MMA znana jest tak\u017ce pod innymi nazwami: metoda 111 oraz spawanie elektrod\u0105 otulon\u0105. Ostatnia z tych nazw jest nawi\u0105zaniem do zastosowania konkretnego akcesorium w procesie zespalania materia\u0142\u00f3w. Jest nim elektroda zbudowana z rdzenia (element metaliczny) i os\u0142aniaj\u0105cej go specjalnej otuliny (masa okrywaj\u0105ca o r\u00f3\u017cnym sk\u0142adzie chemicznym). Elektroda wytwarza \u0142uk elektryczny pomi\u0119dzy ni\u0105 a materia\u0142ami, kt\u00f3re maj\u0105 zosta\u0107 po\u0142\u0105czone. W tym czasie, pod wp\u0142ywem energii cieplnej o bardzo wysokiej temperaturze, otulina topi si\u0119, uwalniaj\u0105c opary gazu oraz \u017cu\u017cel. Ich zadaniem jest g\u0142\u00f3wnie ochrona po\u0142\u0105czenia spawanego przed wp\u0142ywem atmosfery i zbyt szybkim zakrzepni\u0119ciem materia\u0142\u00f3w.    MMA a TIG, MIG, MAG  Kluczow\u0105 r\u00f3\u017cnic\u0105 pomi\u0119dzy MMA a metodami TIG, MIG, MAG jest d\u0142ugo\u015b\u0107 elektrody. W wypadku MMA, jej d\u0142ugo\u015b\u0107 podlega skracaniu, tak wi\u0119c uchwyt elektrody pozostaje w zmiennej odleg\u0142o\u015bci od przedmiotu spawania. W zwi\u0105zku z tym, nale\u017cy d\u0105\u017cy\u0107 do utrzymania sta\u0142ej odleg\u0142o\u015bci mi\u0119dzy jeziorkiem spawalniczym (stopiona warstwa materia\u0142u) a sam\u0105 elektrod\u0105. Taka umiej\u0119tno\u015b\u0107 wymaga zar\u00f3wno znajomo\u015bci rzeczy, jak i praktycznego treningu.
