    • PROBLEM TO BE SOLVED: To securely perform welding at a crossover point and improve strength of a welding structure in fillet weld in which weld lines intersect with each other.SOLUTION: A first vertical member 2 and a second vertical member 3 are arranged on a horizontal member 1 orthogonally to each other, so as to form the welding structure. At this time, out of the welding lines A1-A3 formed by making the horizontal member 1, the first vertical member 2 and the second vertical member 3 orthogonally intersecting with each other and the crossover point O where the respective weld lines A1-A3 intersect with each other, hot gas welding is applied to the crossover point O and the weld lines A1-A3 within a predetermined range from the crossover point O by blowing hot air to a welding rod, and extrusion welding is applied to the weld lines A1-A3 outside the predetermined range.
    • 要解决的问题:在交叉点处可靠地进行焊接,提高熔接线相互交叉的焊角焊接结构的强度。 解决方案:第一垂直构件2和第二垂直构件3彼此正交地布置在水平构件1上,以形成焊接结构。 此时,在通过使水平构件1,第一垂直构件2和第二垂直构件3彼此正交的方式形成的焊接线A1-A3和相应的焊接线A1-A3相交的交叉点O 彼此之间,通过向热交换器吹入热空气,在交叉点O的预定范围内,将交叉点O和焊接线A1-A3施加热气体焊接,并将熔接线A1- A3超出预定范围。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a joint welding tool which is available for welding a joint of a resin floor material, and controls hot air blown from a hot air pipe of the joint welding tool to the floor material, and particularly a joint welding tool which imparts a beautiful finish to a joint of a floor material made of an olefin resin. SOLUTION: The joint welding tool 1 for the resin floor material is formed of a resin softening chamber 6, a guide pipe 7, and the hot air pipe 8. The resin softening chamber 6 is equipped with a press-contact portion 5 for press-fitting a softened welding rod 2 into a joint groove 4 in the floor material 3 to fill the groove. The guide pipe 7 leads the welding rod 2 to the resin softening chamber 6. The hot air pipe 8 extends from the resin softening chamber 6 in a direction that is opposite to the press-contact portion 5, for supplying hot air to the resin softening chamber 6. The joint welding tool 1 has a hot air shielding wall 9 at a lower opening of the hot air pipe 8 in a manner extending from a location opposite to the resin softening chamber 6 in a direction of the same, to thereby define a preheated air outlet 10 by the hot air shielding wall 9 and the welding rod 2. Then the width (L) of the preheated air outlet 10 is set in the range of 0.3 to 3 mm. COPYRIGHT: (C)2004,JPO
