National Public Presentation Meeting of Welding Science and Technology was held between October 12 to 15 under the sponsorship of the Central Committee of Korean Federation of Science and Technology.
The public discussion was held in the form of screen meeting. Teachers, researchers, graduate school students, field technicians and Three-revolution team members from over ten institutions including our University, Pyongyang University of Architecture, Pyongyang University of Mechanical engineering, Pyongyang University of Transport, Welding Research Institute of National Academy of Science.
In this forum, several proposals such as those suggested by Cha Kwang Jin, section leader from the Faculty of Materials Science and Technology –“Inverter CO2 shielded gas semi-automatic arc welding equipment” and graduate school student Pak Kwang Jin –“Arc spray process of cool punching die” were highly appreciated as for making success in the research work on new welding methods and localizing equipment, raw materials and resources for welding field.
Besides, several proposals from by our university were estimated valuable.

The research group led by Jang Song Ok, laboratory head at the Faculty of Mining Engineering succeeded in manufacturing a natural graphite brush for shaft grounding and is trying to make further achievements in their research.
They proved scientifically that it is possible to make a brush for shaft grounding with natural graphite and decided the structure, quality and operation system of the material for the brush with high capacity of electro motion and contact property and with improved wear property.
The permissible current density of the brush is 20~30A/㎠, the ratio of wear is about 0.3㎜/1 000㎞ and the spring pressure is around 20㎪.

The research group led by Choe Chol Min, laboratory head at the Faculty of Materials Science and Technology succeeded in manufacturing a splint using AM (additive manufacturing) and is trying to make further achievements.
This light splint of good air permeability manufactured by FDM (fused deposition modeling) helps relieve patients from their burden, reduce complications like skin diseases to shorten the period of treatment.
Figure 1 shows the CT photograph of a patient. Figure 2 displays the model of a splint manufactured with Solidworks using its photograph. Figure 3 shows the arm of a patient who wore the above mentioned splint just after the day of operation.

The National Sci-tech Symposium on Metallic Material was held from September 14 to 16 by online meeting system under the sponsorship of the Central Committee of General Federation of Science and Technology of Korea.
The subject was “Development of Metallic Material based on Domestic Resources”. The participants were lecturers, researchers, postgraduates, field engineers etc. from Kim Chaek University of Technology, Chongjin University of Mining and Metallurgy, Ferrous Metal Institute of the State Academy of Sciences, Hwanghae Iron and Steel Complex and other units.
The essay by Jang Hyon Chol, chief of institute at the Faculty of Materials Science and Technology “Effect of factors on the properties of Al2O3-ZrO2 composite ceramic liner by SHS Gravitational Process” was highly appraised as a great practical significance since he set forth the solutions to the scientific and technological problems arising in the improvement of the features of the inner surface of a steel pipe such as heat resistance and abrasion resistance etc. by relying on domestic materials.
In addition to this several essays presented from KUT were proved to be of value.
