焊接垫板带也有人称为柔韧垫板带、玻璃布垫板带等。这种垫板带国外早已在大型贮箱(罐)、造船、化工容器及核动力管道的焊接中应用。这种垫板优点很多:(1)可以节约60％焊接时间。过去焊接较厚的大直径管道、贮箱(罐)等都是先从里面封底焊,然后再用自动焊机从外面进行焊接。有时,焊工在工件里面封底焊,工作条件很坏,效率低,质量差。改用垫板带进行焊接就不再需要封底了,焊前把垫板带贴到焊缝背面,从正面进行焊接,可以做到单面焊双面成形,而且焊
Welding pad with some people also known as the soft pad with plate, glass cloth with pad plate and so on. This pad with foreign countries already in the large tank (tank), shipbuilding, chemical containers and nuclear power pipe welding applications. This pad has many advantages: (1) can save 60% of the welding time. In the past, thicker welded pipes, tanks, etc. were welded from the back cover first and then from the outside with an automatic welding machine. Sometimes, welders in the workpiece back welding, poor working conditions, low efficiency, poor quality. Switch to the pad with the welding will no longer need to seal the back of the weld plate before the weld attached to the back of the weld from the front, you can do single-sided welding double-sided forming, and welding
