Description

10 15 20 25 30 35 455 275' . länken. Under denna process krokas också i bredvidliggande färdigsvetsade länk. Svetsningen tillgår så att elektriska kontakter, 2, anslutes till båda sidor om länkmaterialets ändar, 4, lämplig spalt, 3, för tändning av ljusbàgen inställes mellan länkmaterialets ändar, 4, spalten, 3, ökas sedan tändning skett för att få det utseende på ljusbågen man önskar. När ändarna, 4, erhållit avsedd svetstemperatur pressas ändarna, 4, ihop så att en vulst uppstår i skarven. 10 15 20 25 30 35 455 275 '. the link. During this process, adjacent pre-welded links are also hooked. The welding is done so that electrical contacts, 2, are connected to both sides of the ends of the link material, 4, suitable gap, 3, for igniting the arc is set between the ends of the link material, 4, the gap, 3, is increased after ignition has taken place to get the appearance of the arc you want. When the ends, 4, have reached the intended welding temperature, the ends, 4, are pressed together so that a bead arises in the joint.

Det av den höga temperaturen vid svetstillfället påverkade zonen är ganska utbredd.The zone affected by the high temperature at the time of welding is quite widespread.

Enligt uppfinningen kapas länkmaterialet,1, i något kortare längder så att en kuts, 5, med ungefär samma diameter som länkmaterialet, 1, kan inpassas i spalten, 3, eller gapet mellan ändytorna, 4, hos länkmaterialet, l. Med en kuts, 5, menas i allmänhet en homogen cylinder vars längd mellan ändytorna ligger ungefär mellan kutsens halva diameter en och en halv gånger dess diameter. I ordet kuts inneslutes dock här även cylindrar med mindre längd. I kutsens, 5, analys skall ingå seghetshöjande legeringsämnen så att vid svetstillfället sådana legeringsämnen i tillräcklig mängd inlegeras i den av höga temperaturer vid svetstillfället i länkmaterialets, 1, ändytor, 4, påverkade zonen. Därmed har man fått en önskad sammansättning i den mest utsatta zonen utan att behöva legera upp hela länkmaterialet. Friktions- svetsníngen går sedan till på vanligt sätt genom att kutsen, 5, roteras och friktionen i ytorna mellan kuts, 5, och länkmaterial, 1, åstadkommer eftersträvad temperatur varefter ytorna pålägges lämplig press. Friktionssvetsning har i jämförelse med brånnsvetsning den stora fördelen att den av den höga temperaturen påverkade zonen i länkmaterialet, 1, avsevärt minskas i förhållande till exempelvis brännsvetsning.According to the invention, the link material, 1, is cut into slightly shorter lengths so that a pellet, 5, with approximately the same diameter as the link material, 1, can be fitted in the gap, 3, or the gap between the end surfaces, 4, of the link material, 1. With a pellet, 5, is generally meant a homogeneous cylinder whose length between the end surfaces is approximately between half the diameter of the cushion one and a half times its diameter. In the word putty, however, cylinders of smaller length are also included here. The analysis of the pellet, 5, shall include toughness-increasing alloying elements so that at the time of welding such alloying substances are sufficiently alloyed into the zone affected by high temperatures at the time of welding in the link material, 1, end surfaces, 4. This has given you the desired composition in the most exposed zone without having to alloy up the entire link material. The friction welding then takes place in the usual way by rotating the pellet, 5, and the friction in the surfaces between the putty, 5, and the link material, 1, produces the desired temperature, after which the surfaces are subjected to a suitable pressure. In comparison with well welding, friction welding has the great advantage that the zone affected by the high temperature in the link material, 1, is considerably reduced in relation to, for example, fire welding.
