Embodiment 2
[0072] The shape of the slit-containing tungsten electrode 1 of the second embodiment of the present invention is shown in figure 2 , figure 2 (a) is the front view, figure 2 (b) is a side view, figure 2 (c) is a bottom view.
[0073] It is also possible to set a plurality of slits 2 at the tip of the electrode 1 to form more than 3 tips ( figure 2 indicates a cruciform-type slit).
[0074] In the case where the above-mentioned slit is a straight line, welding without direction can be sufficiently performed, but especially when the diameter of the tungsten electrode is larger than 5.0mm, the case of the cross can be compared with the case of the straight line. For a more non-directional weld.
[0075] Furthermore, it is also possible to change the conical shape of the tip portion of the tungsten electrode 1 in the above-mentioned embodiment 1 and embodiment 2 into a polygonal pyramid shape not shown in the figure, and obtain the same shape as the above-mentioned slit...
