求翻译：在挡块处新增加的焊口，当挡块四面全部焊接后，它就阻挡了管卡安装。我们建议挡块焊接时，仅焊接三面，安装管卡一侧不焊接。是什么意思？

To stop the new increase in the Weld, when block 4 is all after welding, it blocks the card is installed. We recommend that the block when welding, soldering is only 3 side, install the card side is not solder.

In keeps off the block place new increase the crater, after keeps off around the block to weld completely, it has prevented the tube card installment.We suggested when keeps off the block welding, only welds three, installs tube card one side not to weld.

New welding at the block, when block after all welding on all sides, it blocked the pipe installation. We recommend block welding, welded on three sides only, install the pipe clamp welded side.
