in mubarakeh steel, during 4 years of research and study , they were able to achieve this technologyt the previous welding of the previous welding machine was of gas type with co gas , which is that the cost of gases used in this risk is very expensive and that the quality of this welding is not good. by replacing this welding fiber with the same fiber with a much more accurate wavelength, c2 laser welding wavelength it used to be 10 microns, but now it is 1 micron , which means that it is done with very high precision and quality . now mr. mr. dr. taybia should praise the quality, but what we, our friends , have achieved is that there is room for all the dear ones in this field. i would like to express my gratitude to both mubarakeh steel company and my colleagues at the laser science center. very good, dr. taybia. you also say that until now, in the steel industry, you came from this product. now, dr. esdalai also said that it has been used for the past month, but there is a precedent for using the achievements of experts in the nuclear industry in this regard, can you explain the
