With soft hardware, the control system can achieve two kinds of welding methods, fullwelding and orientation welding by weld processing logic automatic control.
利用软硬件结合，实现焊接的时序控制以及满焊和定位焊两种焊接方式。

The results show that the system is stable and the data gained by this system are accurate, which can meet the measuring demand of the large diameter fullwelding of the ball-valve.
结果表明，该系统稳定可靠，所测量出来的数据准确，可以满足大直径全焊接阀体球阀焊接过程的检测要求。
