Abstract
The invention discloses a method for inspecting the quality consistency of an undercarriage product made of direct laser deposited and formed A-100 steel. The method for inspecting the quality consistency of the undercarriage product made of the direct laser deposited and formed A-100 steel includes the following steps that firstly, on a blank drawing of the undercarriage product made of the direct laser deposited and formed A-100 steel, the portions of the preset sizes of the product to be inspected are taken from the maximum sectional area position in the perpendicular forming and deposition growth direction to the two ends in the deposition growth direction, and the obtained drawing is called as an inspection test blank drawing; secondly, the process parameters the same as those of the undercarriage product made of the direct laser deposited and formed A-100 steel are adopted for manufacturing a product quality consistency inspection test blank; thirdly, the maximum sectional area position of the test blank in the perpendicular forming and deposition growth direction is cut into two segments to form a blank to be inspected; and fourthly, quality consistency inspection is performed, so that whether the result of the blank to be inspected is consistent to the inspection test blank drawing or not is tested. By the adoption of the method, the performance and the quality of the undercarriage product made of the direct laser deposited and formed A-100 steel can be objectively evaluated.
