Description
Vynález aa týká spósobu elektrotroskového zvárania materiálov velkých hrúbok pásovými elektrodami.FIELD OF THE INVENTION The invention relates to a method for the electrode welding of large thickness materials by strip electrodes.
Elektrotroskové zváranie materiálov velkých hrúbok, to je materiálov hruběích ako 450 mm je sposob technicky progresívny a ekonomicky výhodný. Nevýhodou tohoto spósohu je, že z dovedu tepelného posobenia, dochádza k nerovnoměrnému nataveniu zváraných hrán po zváranej hrúbke. Naviac na okrajoch zvaru při chladiacich príložkach, kde je zvýšený odvod tepla zo zvarového kovu, dochádza k nedokonalému pretaveniu zvarových hrán a kvalita formovania zvarového kovu je nedostatočná. Takto formovaný zvarový kov vytvára vruby, ktoré pri tuhých zvarencoeh možu spósobova! vznik trhlin. Sú známe spósoby, ktoré sa snažia tieto nedostatky odstráni!, napr. spósob podlá autorského osvedčenia ZSSR č. 279 831.Electroslag welding of materials of great thickness, i.e., materials thicker than 450 mm, is a technique which is technically progressive and economically advantageous. The disadvantage of this method is that, due to the ability of thermal agitation, the weld edges are unevenly melted over the weld thickness. In addition, at the edges of the weld with cooling plates, where heat dissipation from the weld metal is increased, the weld edges are incompletely remelted and the quality of the weld metal formation is insufficient. The weld metal formed in this way creates notches which can be caused by rigid weldments! cracks. Methods are known which seek to overcome these deficiencies! method according to USSR copyright certificate no. 279 831.
Nevýhodou tohoto spósobu je, že k realizácii je potřebné poměrně zložité zariadenie, ktoré sa musí připravil před zvóraním, tento spósob zvárania si vyžaduje dokladná izoláciu přídavného materiálu voči zváranému materiálu, s čím vznikajú vo výrobě nároky na přípravu a predlžuje sa čas zvárania materiálov.The disadvantage of this method is that a relatively complicated device is required for the implementation, which must be prepared prior to welding, this welding method requires the documentary insulation of the filler material against the welded material, which creates production demands in production and increases the welding time of the materials.
Ďalší spósob je známy z autorského osvedčenia ZSSR č. 469 559, ktorý má nevýhodu v tom, že drót podávaný zboku do troškového kúpeía k zváraným hranám je podávaný cez stenu kryštalizátora, čo celý proces komplikuje a robí technicky zložitý. Spoločnou nevýhodou týchto spósobov je, že nie je možné takto zváraí zvarove zložité výrobky.Another method is known from the USSR's copyright certificate no. 469 559, which has the disadvantage that the wire fed from the side into the splash bath to the welded edges is fed through the wall of the crystallizer, which complicates the process and makes it technically complex. A common disadvantage of these methods is that it is not possible to weld such complex welded products.

Vyššie uvedené nedostatky sd odstránené do značnej miery aposobom pódia vynálezu, ktorého podstata spočívá v tom, že elektrotroškové zváranie materiálov velkých hrúbok pásovou elektrodou sa vykonává tak, že s pásovou elektrodou sa súčaane podává do troškového kúpela přídavný materiál a to tak, že rychlost podávania pásovej elektrody je od 0,8 do 3 m za hodinu a rýchlost podávania přídavného materiálu je od 80 do 140 m za hodinu. Sirka pásovej elektrody a vodiacej trubky sa volí tak, aby tieto boli vo vzdialenosti od 5 do 25 mm do vnútra zvarenca od plochy po ktorej aa posúvajú chladiace príložky.The above-mentioned drawbacks sd have been eliminated to a large extent and in accordance with the invention, which is based on the fact that electrospray welding of large thickness materials by a strip electrode is carried out by simultaneously feeding the strip electrode with additional material into the droplet bath so that the electrode is from 0.8 to 3 m per hour and the feed rate of the filler material is from 80 to 140 m per hour. The width of the band electrode and guide tube is selected such that they are at a distance of 5 to 25 mm to the interior of the weldment from the surface over which aa slides the cooling plates.
Sposobom zvárania podlá vynálezu sa dosiahne váčší tepelný příkon a tým aj rovnoměrné natavovanie hrán a dokonalé formovanie zvarovaného kovu v oblasti najvačšifeho posobenia chladiacích príložiek. Elektrotroskovým zváranim podlá vynálezu sa odstráni vznik trhlin vo zvarovom kove, ktoré vznikali v dósledku nerovnoměrného chladnutia zvarovaného kovu.The welding method according to the invention achieves a higher thermal input and thus even melting of the edges and perfect forming of the welded metal in the region of the greatest posibility of the cooling plates. Electro-fusion welding according to the invention eliminates the formation of cracks in the weld metal resulting from the uneven cooling of the welded metal.
Na pripojenom výkrese je bližšie objasněný sposob podlá vynálezu.The method according to the invention is explained in more detail in the accompanying drawing.
Na obrázku 1 a 2 je znázorněný sposob elektrotroskového zvárania podlá vynálezu.Figures 1 and 2 show the method of electroslag welding according to the invention.
Elektrotroskové zváranie materiálu 1 velkých hrúbok sa vykonává pásovou elektrodou 2, ktorej koniec smerujúci k chladiacej príložke 3 se opatří vodiacou trubkou 4 pře přídavný materiál 5. Pásová elektroda 2 sa súčasne s přídavným materiálom 5 podává do troškového kúpeía 6 tak, že rýchlost podávania páaovej elektrody 2 je od 0,8 do 3 m za hodinu a rýchlost podávania přídavného materiálu je od 80 do 140 m za hodinu. Sirka pásovej elektrody 2 sa volí tak, aby vzdialenost od konca vodiacej trubky 4 po okraj zváraného materiálu 1 velkých hrúbok bola od 5 do 25 mm smerom do vnútra zváraného materiálu 1.Electrode welding of the material 1 of large thicknesses is performed by a strip electrode 2, the end of which is directed towards the cooling plate 3 with a guide tube 4 over the filler material 5. The strip electrode 2 is fed together with the filler material 5 2 is from 0.8 to 3 m per hour and the feed rate of the filler material is from 80 to 140 m per hour. The width of the band electrode 2 is chosen such that the distance from the end of the guide tube 4 to the edge of the welded material 1 of large thickness is from 5 to 25 mm towards the inside of the welded material 1.

V druhom případe sa zvolila rýchlost podávania pásovej elektrody 2,8 m za hodinu a rýchlost podávania přídavného materiálu 120 m za hodinu, šířka pásovej elektrody bola zvolená tak, že vzdialenoí od konca vodiacej trubky po okraj materiálu velkej hrůbky bola 22 mm smerom do vnútra zváracieho materiálu. V obidvoch prípadoch boli dosiahnuté zvary v3aka tepelnému příkonu bez trhlin a vrubov a vyhověli pevnostným skúškam.The electrode welding method according to the invention was used for welding materials of a depth of 1100 mm. In the first case, the feed rate of the band electrode was chosen to be 1 m per hour and the feed rate of the filler material was 94 m per hour, the band electrode width was chosen such that the distance from the end of the guide tube to the edge . In the second case, a feed rate of 2.8 m per hour and feed rate of filler of 120 m per hour were selected, the width of the band electrode was chosen such that the distance from the end of the guide tube to the edge of the material was 22 mm towards the inside material. In both cases, the welds were achieved in terms of heat input without cracks and notches and complied with the strength tests.
