이때 상부엔드캡(50)의 가장자리는 용기몸통(40)의 상단부가 지지되는 맞대기용접의 최적조건을 위한 수평부(51)와, 용기몸통(40)의 상단부 내주면에 면접촉되는 수직부(52)를 가지는 채널(53)이 형성된 구조를 가진다. 부호 80은 용기몸통(40)의 상단부측 확경부(41) 끝단과 이에 걸친 상부엔드캡(50)의 수평부(51)를 상호 맞대기 용접하여 되는 용접부를 가시화하여 나타낸 것이다.At this time, the edge of the upper end cap 50 is a horizontal portion 51 for the optimum condition of the butt welding, the upper end of the container body 40 is supported, and the vertical portion 52 in surface contact with the inner peripheral surface of the upper end of the container body 40 Has a structure in which a channel 53 having a) is formed. Reference numeral 80 is a visual representation of a welded portion which is butt welded to the end of the upper end side enlarged diameter portion 41 of the container body 40 and the horizontal portion 51 of the upper end cap 50 therebetween.

그리고 하부엔드캡(60)의 가장자리는 용기몸통(40)의 하단부가 지지되는 맞대기용접의 최적조건을 위한 평면부(61)와, 용기몸통(40) 하단부 내주면과 면접촉되는 접촉부(62)를 가진다. 부호 80'는 용기몸통(40)의 하단부측 확경부(42) 끝단과 이를 받치는 하부엔드캡(60)의 평면부(61)를 상호 맞대기 용접하여 되는 용접부를 가시화하여 나타낸 것이다.And the edge of the lower end cap 60 is a flat portion 61 for the optimum condition of the butt weld that the lower end of the container body 40 is supported, the contact portion 62 in surface contact with the inner peripheral surface of the lower end of the container body 40 Have Reference numeral 80 'is a visual representation of a welded portion which is welded to each other by butt welding the end of the lower end side of the enlarged diameter portion 42 of the container body 40 and the flat portion 61 of the lower end cap 60 supporting it.

한편, 용기몸통(40)을 성형하는 공정은 먼저 도3 및 도4에 도시된 바와 같이 용접으로 원통형으로 형성한다. 이때 용접에 의한 비이드(40a)가 용기몸통(40)의 내외주면에 형성되게 된다.On the other hand, the process of forming the container body 40 is first formed in a cylindrical shape by welding as shown in Figs. At this time, the bead 40a by welding is formed on the inner and outer peripheral surfaces of the container body 40.

이러한 상태에서 도5에 도시된 바와 같이, 확관부가 형성된 상부 및 하부금형(100)(200)에 용기몸통(40)을 개재시켜 양단부를 확관시킨다. 이때 용기몸통(40)의 내외주면에 형성된 용접비이드(40a)가 제거된다. 또한 용기몸통(40)의 절단시 그 양단부에 형성되는 불규칙적이고 날카로운 부분이 제거되어 매끄러운 수평면을 형성하게 된다. 따라서 상부 및 하부엔드캡(50)(60)과의 결합을 위한 진원이 형성되게 된다.In this state, as shown in Figure 5, through the container body 40 in the upper and lower molds 100, 200 formed with the expansion pipe is expanded both ends. At this time, the welding bead 40a formed on the inner and outer circumferential surfaces of the container body 40 is removed. In addition, when the container body 40 is cut, irregular and sharp portions formed at both ends thereof are removed to form a smooth horizontal surface. Therefore, a round shape for coupling with the upper and lower end caps 50 and 60 is formed.

이러한 본 발명에 따른 가스용기의 구성에 있어서, 상기 상부 및 하부엔드캡(50)(60)은 용기몸체(40)와 용접효율이 높은 맞대기용접으로 접합되어진다.In the configuration of the gas container according to the present invention, the upper and lower end caps 50 and 60 are joined to the container body 40 by the butt welding with high welding efficiency.
