Abstract

Elektroda siluminowa do spawania aluminium i jego stopów, o otulinie zawierającej chlorki potasowców, wapniowców i innych metali, znamismna tyra, że zawiera, w procentach wagowych, 0-5% chlorku magnezu, 0-5% chlorku wapnia, 0-10% siarczanu potasu, reszta - chlorki i fluorki potasowców i wapniowców.Silumin electrode for welding aluminum and its alloys, with a coating containing Chlorides of potassium, calcium and other metals, a characteristic trait that it contains, as a percentage by weight, 0-5% magnesium chloride, 0-5% calcium chloride, 0-10% potassium sulfate, the rest - chlorides and fluorides of potassium and limestone.

Description

Przedmiotem wynnlazku Jest elektroda sHuminowa (A1S15) do spawania aluminium i Jego stopdw, szczególnie we wszelkiego rodzaju pracach remintowych i naprawczych.The subject of the invention is the SHUMIN electrode (A1S15) for welding aluminum and its alloys, especially in all kinds of renovation and repair works.

Znane dotychczas otulone elektrody aluminiowe i siluminowe zawierają w otulinie chlorki i fluorki potasowcdw, wapniowcdw i innych metali w znacznych ilościach. Elektrody te nie zawsze odznaczaję się stabilnym Jarzeniem się łuku, trwałośclę otuliny i łatwościę usuwania ZuZla ze spoiny. Występuję rdwniez trudności przy produkcji tych elektrod, zwięzane z procesem ich prasowania. Szczegdlnie korzystne własności ujawnia chlorek wapnia i magnezu, lecz zbyt duże ilości tych chlorkdw przyczyniają się do skłonności rozkładu otulin elektrodowych.The previously known coated aluminum and silumin electrodes contain large amounts of chlorides and fluorides of potassium, calcium and other metals in their coating. These electrodes are not always characterized by stable glow of the arc, durability of the cover and easy removal of ZuZla from the weld. There are also difficulties in the production of these electrodes, related to the process of their pressing. Particularly favorable properties are revealed by calcium and magnesium chloride, but too large amounts of these chlorides contribute to the tendency to decompose the electrode coatings.

Elektroda siluminowa według wynalazku charakteryzuje się tym, ze zawiera w otulinie małe ilości chlorkdw, przy czym chlorku magnezu zawiera 0-5% wagowych, chlorku wapnia 0-5% wagowych oraz siarczan potasu w ilości 0-10% wagowych, reszta chlorki i fluorki potasowcdw i wapniowcdw. W celu rozrdZnienia elektrod otulina może zawierać barwnik, zwłaszcza indygo lub ultramarynę.The silumin electrode according to the invention is characterized by the fact that it contains small amounts of chlorides in the coating, the magnesium chloride containing 0-5% by weight, calcium chloride 0-5% by weight and potassium sulphate in the amount of 0-10% by weight, the rest chlorides and potassium fluorides and calcium The coating may contain a dye, in particular indigo or ultramarine, for the purpose of thinning the electrodes.

Zaletę elektrod według wynalazku jest poprawa stabilności jarzenia się łuku przy spawaniu, poprawa trwałości otulin elektrodowych, oraz ułatwienia w procesie produkcji elektrod.The advantage of the electrodes according to the invention is the improvement of the stability of the arc glow during welding, the improvement of the durability of the electrode coatings, and the facilitation of the electrode production process.
