七十年代单面焊双面成形的衬垫仍要用电磁或机械方法卡紧固定,焊接时衬垫不易随钢板变形,影响焊缝质量。八十年代国外出现了库德式(Kuder)粘接垫,广泛应用于造船、压力容器焊接工艺中。1983年我校与兄弟单位协作研制成功手工焊、埋弧焊、氩弧焊及CO_2气体保护焊的粘接软垫、经过渤海船厂、新河船厂、天津化工石油设备厂、化工第九化建公司
In the seventies single-sided welding double-sided forming pad still electromagnetic or mechanical method of fastening, welding pad is not easy with the deformation of steel, affecting the quality of the weld. Eighties abroad appeared Kuder (Kuder) adhesive pads, widely used in shipbuilding, pressure vessel welding process. In 1983, our school collaborated with our brothers to develop the adhesive cushion for hand welding, submerged arc welding, argon arc welding and CO 2 gas shielded welding.
