Abstract: PURPOSE: To join steel materials, such as thick pipes, with high quality by improving efficiency of energy utilization in a short joining time by using a plasma arc as a heating source by obtaining the wide width of the plasma arc through magnetic drive and then by pressure-welding them after heating only a required part.  
     CONSTITUTION: After plasma pressure welder 41 mounted on steel pipes 18 and 18' across joint part 2 is tightened and fixed, moving device 17 is moved to position plasma torch 3 right over joint part 2. Next, Currents are fed from plasma power source 4 to plasma torch 3 and from driving power source 10 to magnetic coils 9 and 9' to generate plasma arc 15 of widened width from torch 3, heating joint part 2. At this time, device 17 is moved reciprocally in the axial direction to heat the circumference of joint part 2 by about one and half the width of the pipe and when the temperature attains to 1,300°C or above, joint part 2 is pressure and welded. As a result, steel pipes 18 and 18' can be joined together in a short time through high-efficiency heating of arc 15 and heating efficiency is high; so that while the power source capacity required is relatively small, a pipeline can be formed with efficiency.

At this point of time, the output of a position detector 60 allowed to correspond to the forward and backward movement of the bed 50 is stored in the CPU memory 7A within a CPU 7. Next, the bed 50 is moved to the point where the beam light 30A coincides with a point becoming a target when the examinee is looked from the outside. The output of the position detector 60 at this time is sent to the CPU 7 and the difference with the previously stored data is taken to make it possible to know the distance therebetween. This measured value is stored in the memory 7A within CPU 7 and the bed 50 is moved so that the position matched with the beam light 30A of the light marker 30 at first comes to the center O of a static magnetic field to perform imaging. By this procedure, the distance DELTAx between the target point and the center O of the static magnetic field is easily calculated.
