Description

_84ÛÛ~345~8 kylning vid drift av svetsverktyget i produktionstakt.
Sådan kylning ger förluster som avsevärt försämrar verk- ningsgraden.
En annan metod gär ut på att man placerar ferromagne- tiskt material med hög permeabilitet, t.ex. mjukjärn, i anslutning till svetsstället(-ena) för att pä känt manér "uppsamla" det magnetiska flödet i materialet av hög perme- abilitet. Denna princip är hämtad från lägfrekventa appli- kationer, t.ex. elkrafttransformatorer, och har ej sådana egenskaper att den fullt ut, med bibehällna fördelar, kan utnyttjas i högfrekvenstillämpningar. Med “högfrekvens“ i detta sammahang förstås frekvens av åtminstone storleksord- ningen kHz, vanligen 10-50 kHz. Högre frekvens kan även ifrâgakomma, speciellt om man eftersträvar små inträng- ningsdjup i det elektriskt ledande materialet i svets- stället. "Koncentration" av energi till små inträngnings- djup kan emellertid medföra genombränning av materialet.
Vid mycket höga frekvenser kommer dessutom dielektriska fenomen att påverka slutresultatet.
Uppfinningen syftar till att erbjuda ett alternativ till de kända induktionssvetsmetoderna. Arrangemanget enligt uppfinningena - har det visat sig - eliminerar högst påtagligt bristerna hos de kända anordningarna och visar sig dessutom vara synnerligen tillverkningsvänligt och lätt att hantera.
Anordningen enligt uppfinningen omfattar elektriskt ledande, magnetiskt fält alstrande och fältet mot ett svetsställe riktande arrangemang. Anordningen utmärks av för modifiering av fältet inrättat skikt omfattande elekt- riskt ledande partiklar fördelade i en bärarmassa av elekt- riskt oledande material.
Lämpligen omfattar det elektriskt ledande arrangemanget en slinga, och det modifierande skiktet är anordnat inom slingan för att avskärma förutbestämd area av omrâdet innanför slingan.
Bärarmassan utgörs företrädesvis av gjutbart material, t.ex. epoxiharts.
Partikelmängden i massan varierar beroende på till- 8400345-8 lämpning, men lämpligen ingår partiklarna i massan i en mängd av upp till ungefär 50 viktsprocent.
Partikelstorleken varierar likaså, men som exempel kan nämnas partiklar av storleken pm upp till några tiotal pm.
Partiklarna kan med fördel utgöras av kopparspân, kim- rök eller annat elektriskt ledande material.
En utföringsform av uppfinningen kommer nu att beskri- vas med hänvisning till bifogade ritning, där Fig. 1 i tvärsektion och dellängdsektion visar ett svets- verktyg enligt uppfinningen på ett lock till en be- hållare, och Fig. 2 visar en ändvy av svetsverktyget sett från "pulver- skärmsidan".
Svetsverktyget omfattar i princip en slingformig, mer eller mindre cirkulärt sluten elektrisk ledare ll, som ver- kar som magnetiskt fält alstrande svetsinduktor. Svetsin- duktorn ll är helt eller delvis inbäddad i en kropp 12, lämpligen av gjutbart material, t.ex. epoxiharts. Inom slingans begränsningskanter är en urtagning 13 utformad till ett djup av storleksordningen nâgra millimeter och med en radiellt yttre rand ävenledes på ett avstånd av några millimeter från kroppens 12 koniska anliggningsparti 14.
I urtagningen 13 är anordnat en kropp 15 omfattande en bärarmassa 16 och däri uppburna partiklar 17. Bärarmassan är elektriskt oledande och består lämpligen av gjutbart material, t.ex. epoxi. Partiklarna är av elektriskt ledande material, t.ex. koppar, kimrök, etc. Storleksordningen för partiklarna ligger i intervallet pm till nâgra tiotal pm.
Verktygets 10 koniska anliggningsparti 14 ligger invän- digt an mot randen av ett behällarlock 18, som av partiet 14 pressas mot insidan av toppkanten hos en behällarstomme 19. Locket 18 består av ett yttre plastskikt, t.ex. poly- propen, med en tjocklek av några hundratal pm och ett innanför plastskiktet beläget barriärskikt av metalliskt material, t.ex. aluminiumfolie, med en tjocklek av stor- leksordningen ungefär l0_pm.
Svetsverktyget 10 är med sin koniska ände 14 infört till operativ position och det svetsomràde som är aktuellt 840Û345-8 är alltså omrâdet mellan behâllarens 19 topp och lockets 18 uppâtriktade fläns.
Strömmen genom svetsinduktorn ll ger på känt sätt ett magnetiskt flöde axiellt genom slingan, och detta flöde pulserar i princip med den pâtryckta strömmens frekvens. Av en här ej utredd anledning kommer emellertid flödet ej att nämnvärt avkännas i behållarlocket i området under den pulverfyllda urtagningen 13. Dessutom, jämför fallet med den kortslutna elektriskt ledande slingan, kommer ej heller kroppen 15 att uppvärmas nämnvärt - inte ens under läng- varig drift av svetsverktyget i en maskínlinje för förslut- ning av behållare.
Man kan konstatera att det magnetiska flödet från svetsinduktorn avskärmas från annat än randomràdet av behållarlocket, d.v.s. det önskade svetsomràdet. Kvalita- tivt sett föreligger alltså en magnetisk resulterande flödesbana för det aktuella magnetiska flödet (frekvens av storleksordningen 30 kHz) som av ett här ej diskuterat sam- band undviker området vid den pulverbemängda kroppen. Även om det aktuella utföringsexemplet avser värmning av ringformigt svetsomrâde, inses att principen med pulver- bemängd massa även kan komma till användning i andra sammanhang. Patentkraven återspeglar det just sagda.
