Description

Werkwij ze voor het door middel van lassen verbinden van een langgerekt element, zoals een rail, met een ondergrond.Method for connecting an elongated element, such as a rail, to a substrate by welding.

De uitvinding heeft betrekking op een werkwijze voor het door middel van lassen verbinden van een langgerekt element, 5 zoals een rail, met een ondergrond.The invention relates to a method for connecting an elongated element, such as a rail, to a substrate by welding.

Op baggervaartuigen wordt bijvoorbeeld in bepaalde gevallen gebruik gemaakt van een over het vaartuig verrijdbare kraan of wagen. De rails waarover de kraan of wagen rijdt moeten door lassen vast met het dek of een ander deel van het 10 vaartuig worden verbonden.On certain dredging vessels, for example, use is made of a crane or wagon that can be moved over the vessel. The rails over which the crane or carriage travels must be firmly connected to the deck or another part of the vessel by welding.

De rails worden vervaardigd uit een speciale slijtbe-stendige staalsoort zoals bijvoorbeeld 30Mn5. Hierbij is het noodzakelijk het materiaal bij het lassen voor te verwarmen en wel tot ongeveer 200 °C. Dit is uiteraard bij het vastlassen 15 aan het dek bijzonder moeilijk uit te voeren. Er zou een grote hoeveelheid staal moeten worden voor-verwarmd, terwijl veel warmte door geleiding verloren gaat.The rails are made from a special wear-resistant steel type such as, for example, 30 Mn5. Hereby it is necessary to pre-heat the material during welding and to about 200 ° C. This is of course particularly difficult to carry out when welding to the deck. A large amount of steel should be pre-heated, while much heat is lost due to conduction.

In verband hiermee is men wel zodanig te werk gegaan dat de rail eerst wordt voorzien van een er op gelaste bufferlaag, 20 zodat bij het vast lassen van de rail aan het dek niet meer voor-verwarmd hoeft te worden.In connection with this, work has been carried out in such a way that the rail is first provided with a buffer layer welded on it, so that when the rail is welded to the deck it is no longer necessary to pre-heat.

Daarbij doet zich dan echter nog wel het bezwaar voor, dat door het lasproces zodanige spanningen in het materiaal worden opgewekt, dat de rail niet geheel recht blijft. De 25 dwars-doorsnede van de rail is namelijk relatief gering ten opzichte van het materiaal van het dek van het vaartuig waarop de rail wordt vastgelast. Door de vervorming van de rail is het moeilijk binnen de gestelde maat-toleranties te blijven.In that case, however, there is still the drawback that the welding process generates such stresses in the material that the rail does not remain completely straight. This is because the cross-section of the rail is relatively small with respect to the material of the deck of the vessel on which the rail is welded. Due to the deformation of the rail, it is difficult to stay within the specified dimensional tolerances.

Volgens de uitvinding worden deze bezwaren nu opgeheven 30 doordat de rail eerst door middel van laser-lassen wordt verbonden met ten minste één tussen-strip welke strip of strippen daarna direct of indirect aan de ondergrond worden vastgelast.According to the invention, these drawbacks are now eliminated in that the rail is first connected by means of laser welding to at least one intermediate strip, which strip or strips are then welded directly or indirectly to the substrate.

Gebleken is dat bij laser-lassen de vervorming na het 35 lassen bijzonder gering en wel nagenoeg nihil is.It has been found that with laser welding, the deformation after welding is extremely low and is practically nil.

Volgens een uitwerking van de uitvinding zal zodanig te werk worden gegaan dat ter weerszijden van de voet van de rail H een tussen-strip wordt aangebracht.According to an elaboration of the invention, work will be carried out in such a way that an intermediate strip is provided on either side of the foot of the rail H.

Voor de tussen-strip kan gebruik worden gemaakt van een staalsoort met een laag koolstof equivalent en wel qua mecha- nische eigenschappen minimaal equivalent aan die van het 5 onderliggende materiaal.For the intermediate strip use can be made of a steel type with a low carbon equivalent and in terms of mechanical properties at least equivalent to that of the underlying material.

De staalsoort van de tussen-strip kan op normale wijze H aan het dek van het vaartuig worden vastgelast.The steel grade of the intermediate strip can be welded to the deck of the vessel in the normal way.

I Bij een indirecte verbinding met de ondergrond kan ge- I bruik worden gemaakt van een overgangs-strip waaraan de twee, I 10 ter weerszijden aan de voet van de rail daaraan vastgelaste, I tussen-strippen worden vastgelast.In the case of an indirect connection to the ground, use can be made of a transition strip to which the two intermediate strips welded thereto on either side at the base of the rail are welded.

I Wanneer de hardheid van het materiaal van de rail in de zone, die is beïnvloed door de warmte die bij het lassen van I de rail aan de tussen-strip werd opgewekt, te hoog is geworden I 15 kan de rail tezamen met de er aan vastgelaste tussen-strip dan I wel tussen-strippen en de eventueel aanwezige overgangs-strip I worden onderworpen aan een gloei-behandeling.If the hardness of the material of the rail in the zone, which is influenced by the heat that was generated during the welding of the rail to the intermediate strip, has become too high, the rail can be combined with the additional welded intermediate strip or I intermediate strips and any transition strip I present are subjected to an annealing treatment.

I Hierdoor kan de hardheid weer worden gereduceerd tot I ongeveer 300HV10.I This allows the hardness to be reduced again to I approximately 300HV10.

I 20 De uitvinding wordt nader toegelicht aan de hand van een I uitvoerings-voorbeeld, getoond in de tekening waarin een I dwars-doorsnede is weergegeven over een rail 1, die bij de I voet 2 aan weerszijden door middel van laser-lassen 3 is I verbonden met een tussen-strip 4. Na het lassen van de tussen- I 25 strippen 4 aan de rail 1 zal in het algemeen dit samenstel I worden uitgegloeid.The invention is further elucidated on the basis of an exemplary embodiment, shown in the drawing, in which a cross-section is shown over a rail 1, which at the base 2 is on both sides by means of laser welding 3 I connected to an intermediate strip 4. After welding of the intermediate strips 4 to the rail 1, this assembly I will generally be annealed.

I Na het uitgloeien worden de tussen-strippen 4 door middel van de lassen 5 verbonden met het onderliggende materiaal 6 I van het verder niet getoonde vaartuig dan wel met een over- I 30 gangs-strip, die naderhand aan het vaartuig wordt vastgelast.After annealing, the intermediate strips 4 are connected by means of the welding 5 to the underlying material 6 of the vessel, not further shown, or to a transition strip, which is subsequently welded to the vessel.

I In het laatste geval bestaat de mogelijkheid dat de rail 1 I tezamen met de tussen-strippen 4 en de overgangs-strip wordt I uitgegloeid.In the latter case, it is possible that the rail 11 is annealed together with the intermediate strips 4 and the transition strip.
