weld period的意思|示意

By using combined weld operating technique, not only ensured the requirement of weld quality, but also reduced the cost and period of manufacture.

采用组合焊接操作技术，即保证了焊缝焊接质量要求，又大大节约了制造成本，并缩短了制造周期。

The test and analysis show that the period of frames in- crease in turn for the weld connection's, the end-plate connection's and the angle connection's steel frame respectively.

试验和理论分析表明：梁柱节点分别为焊接连接、端板连接、角钢焊接时，其结构的周期依次增大；
