求翻译：管道接口的焊接，应考虑焊接顺序和操作方法，防止受热集中而产生内应力。平焊、立焊、横焊及仰焊应对电流进行调整，平焊电流较大，仰焊电流较小。是什么意思？

Welding pipe joints should be considered welding sequence and method of operation to prevent heat stress concentration arising. Flat welding, vertical welding, horizontal and overhead position welding welding current should be adjusted, flat welding current is larger, Yang welding current is small.

Pipeline interface should be taken into account the welding, welding sequence and methods of operation to prevent heat stress concentration within arising. ping welding, a welding, Wang welding and welding should bend, ping welding current adjustment upward currents, larger welding current is relati

The pipeline connection welding, should consider the welding course and the operating procedure, prevented the being heated centralism has the internal stress.The flat welding, stands welds, the horizontal weld and the overhead welding should carry on the adjustment to the electric current, the flat

Welding of pipeline interfaces, consider the welding sequence and method of operation, prevent heat concentration of internal stress. Flat welding, and cross lap welding, welding and overhead welding current adjustment, large flat welding current, overhead position welding current smaller.
