管道焊接用左挡板及气体保护装置和焊接工装
摘要：
本实用新型涉及管道焊接用左挡板及气体保护装置和焊接工装，气体保护装置包括使用时设置于右待焊接管道中的右挡板和与右挡板独立设置的使用时装入左待焊接管道中的左挡板，左挡板包括左挡板本体，右挡板包括右挡板本体，左挡板本体和右挡板本体的尺寸与待焊接管道的内径相适配，左挡板本体上和/或右挡板本体上设置有气口，当左、右挡板均为插装时，在使用过程中如果需要调节气体保护装置的位置，只需要移动左挡板和/或右挡板即可，同样，当右挡板一体设置于右待焊接管道中时，只需要调节左挡板即可，而不用像现有技术中需要调整尺寸较大的待焊接的管道，该气体保护装置在使用过程中不会影响两个待焊接管道的定位，从而提高了工作效率。
摘要（英）：

The utility model relates to a pipeline welding is with left baffle and gas protection device and welding frock, the gas protection device sets up the right baffle in welded tube is treated on the right side and packs the left baffle of a left side in treating welded tube during with right baffle independent setting's use into when using, left side baffle includes left baffle body, right side baffle includes right baffle body, the size of left side baffle body and right baffle body and the internal diameter looks adaptation of treating welded tube, on the baffle body of a left side and/or be provided with the gas port on the right baffle body, work as a left side, when right side baffle is the cartridge, the position of gas protection device is adjusted in the if necessary in the use, only needs left baffle of removal and/or right baffle can, equally, when right baffle an organic whole sets up in welded tube is treated on the right side, it can only to need to adjust left baffle, and need not be like needing the great welded pipeline of treating of adjustable length among the prior art, this gas protection device can not influence two location of treating welded tube in the use, and therefore the work efficiency is raised.
