Introduction

 

It is a fact that vehicle under racks are often made from a not very robust construction, large and are not too heavy. But now they have tolerances and then either flame or more, Hydraulic directed. A customer said that if he will load it into the truck and sends it to glow, 2/3 come back from the crooked Glüherei. This is demanding, complicated and expensive. But is a reality.

 

If these components vibrates instead annealed tension arm, has the advantage that these components do not discard the vibration. Unannealed and no vibrated have default. This has led especially the auto industry to the fact that vibration Relax was preferable annealing. Anyway, there is today automaker's suppliers the chassis no longer pay the Low stress annealing, only vibrate.

 

 

Pictures speak.

Conclusion

 

The vibration Relax has such a high priority, especially in the automotive industry, will not only be the problem of arrears. But also the fact that the strength of a weld will be reduced by the annealing up to 60%. I.e. a weld seam, performing its task without annealing, has a much higher strength. Today's welding wires and / or electrodes have also made great progress, has thus so far reduced the formerly still often called crack danger that at least we, as a company which thousands of hours with vibration relaxed, never had a case where we had something to do with cracking. This means that our insurance premiums are practically zero in the region and make a few critical voices this argument already gone. For sure,

 

 

Annealed welded structures are less rigid and stable than unannealed. Nevertheless, the side effect will that this does not warp during processing. Therefore, the vibration relaxation is right here not only an alternative that is not only to stress annealing there, but to still have their own, new advanced nature better results for the future of machining and further processing method is in the process of future operations.
