应哈尔滨焊接研究所邀请,苏联科学院北方物理技术研究所科技代表团一行五人在其副所长诺沃巴什率领下于1991年9月4日～11日访问了哈尔滨焊接研究所。双方对惑兴趣的焊接技术问题进行了充分深入地讨论,签订了两所1991～1995年直接科技联系意向书,确定两所今后在低温用低合金高强钢焊接性与焊接工艺方面和在低温条件下焊接金属结构强度研究 At the invitation of Harbin Welding Research Institute, a delegation of five scientists from the Northern Institute of Physics and Technology of the Soviet Academy of Sciences visited Harbin Welding Research Institute from September 4 to September 11, 1991, led by his deputy director Novo Basush. The two parties discussed the issue of welding technology which is of interest to both sides and concluded two direct letters of intent on scientific and technological cooperation from 1991 to 1995 to determine the two future applications of low alloy high strength steel for welding and welding at low temperature and at low temperature Study on Structural Strength of Welded Metal
