METHODS FOR PREPARATION OF SHEETS TO BE USED FOR FABRICATION OF A WELDED STEEL BLANK AND FABRICATING A WELDED BLANK - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240042556 titled 'METHODS FOR PREPARATION OF SHEETS TO BE USED FOR FABRICATION OF A WELDED STEEL BLANK AND FABRICATING A WELDED BLANK

Simplified Explanation

The abstract describes a method for preparing steel sheets for fabricating a welded steel blank. The method involves removing part of the metal alloy layers in peripheral zones of pre-coated steel sheets by ablating the pre-coatings to define ablation zones.

  • The method involves removing metal alloy layers in peripheral zones of pre-coated steel sheets.
  • The removal is done by ablating the pre-coatings in the peripheral zones.
  • Ablation creates defined ablation zones on the steel sheets.
  • The peripheral zones are located on either side of the median plane of the steel sheets.

Potential Applications:

  • This method can be used in the fabrication of welded steel blanks.
  • It can be applied in industries that require the use of steel sheets, such as automotive, construction, and manufacturing.

Problems Solved:

  • The method solves the problem of removing metal alloy layers in peripheral zones of pre-coated steel sheets.
  • It provides a precise and efficient way to define ablation zones on the steel sheets.

Benefits:

  • The method allows for the preparation of steel sheets for fabricating welded steel blanks.
  • It ensures the removal of metal alloy layers in peripheral zones, improving the quality of the final product.
  • The method offers a precise and controlled process, reducing the risk of damage to the steel sheets.


Original Abstract Submitted

a method for the preparation of steel sheets for fabricating a welded steel blank is provided. the method includes a step of removing at least part of the first and second metal alloy layers in first and second peripheral zones of pre-coated steel first and second sheets, respectively, by simultaneously ablating the first and second precoatings in the first and second peripheral zones of the pre-coated steel first and second sheets to define first and second ablation zones, the first and second peripheral zones being zones of the first and second principal faces closest to the median plane and located on either side of the median plane.
