摘要： PURPOSE:To improve the follow-up characteristic and profiling accuracy of a torch by bending a tungsten electrode of a welding torch to a prescribed angle, rotating the welding torch at a prescribed angle with respect to a welding material and maintaining the tip of the electrode at a specified distance from the welding material. CONSTITUTION:A TIG welding torch 21 and a tungsten electrode 22 are rotated in the direction where welding progresses. The arc voltage of the electrode 22 is detected and the vertical direction of a torch 21 is controlled to make the arc voltage equal to a set voltage value, by which a distance L1 is adjusted to maintain the length of the arc 22a at an adequate value. The torch 21 and the electrode 22 are then rotated 90 deg. toward the side wall Wa of a welding material W. The arc voltage of the electrode 22 is detected and the forward and backward direction of the torch 21 is controlled to make said voltage equal to the set voltage value. A distance L2 is adjusted to maintain the length of the arc 22b at the adequate value.

摘要： PURPOSE:To eliminate the waste of materials and to shorten a stop time in formation by forming projections in specific shapes at the ending terminal part of one blank material for a needlelike fin and at the starting terminal part of the other blank material, and welding those projection parts one over another. CONSTITUTION:The ending terminal part 2s of the needlelike fin blank material 2 is superposed upon the starting terminal part 12a of another blank material 12 and they are cut with a cutter, etc., as shown lines A-A and B-B; and the projection parts 11 and 11a which are nearly as wide as the remaining uncut parts as wing parts for a heat conduction pipe are formed at the ending and starting terminal parts 2a and 12a. Only those projection parts 11 and 11a are superposed upon the blank materials 2 ans 12 without any breadthwise shift between the blank materials 2 and 12 and the overlap parts are welded together. This jointing method secures enough strength against tensile force in winding to the heat cnduction pipe and manufactures the successive heat conduction pipe with the needlelike fin.
