従来、熱可塑性樹脂部材の溶接を行なう場合、熱風溶接

溶接法はノズルより熱風を溶接箇所に吹きつけて溶接を
行なう方法であるが、この方法だとノズルより吹き出さ

り、熱風の対流により溶接部以外の箇所に熱影響が及び
、被溶接部材が変形、変質したりするという問題がある
。Conventionally, when welding thermoplastic resin members, it is common to use hot air welding or hot plate welding. The hot air welding method is a method of welding by blowing hot air from a nozzle onto the welding area, but with this method, the pressure of the hot air blown out from the nozzle may create wavy irregularities on the surface of the welding area, or the convection of the hot air may cause welding. There is a problem in that heat affects areas other than the welded part, resulting in deformation or alteration of the welded member.
一方、熱板溶接法は、溶接箇所に熱板を溶接させて被溶
接部材を溶接させ結合させる方法であるが熱板を溶融箇
所から引き離す際、溶融樹脂が熱板から完全に離れず糸
を引くという現象が生じる。On the other hand, hot plate welding is a method in which a hot plate is welded to the welding point to weld and join the parts to be welded, but when the hot plate is pulled away from the molten spot, the molten resin does not completely separate from the hot plate and the threads are removed. A phenomenon of pulling occurs.
つまり繊維状のハリが生じるという問題がある。In other words, there is a problem in that fibrous firmness occurs.
本発明は上記問題点に鑑みて案出されたもので、溶接層
の厚さを均一にし、溶接部以外の箇所への熱影響を防ぎ
、パリの発生を防止することを目的とする。The present invention was devised in view of the above-mentioned problems, and an object of the present invention is to make the thickness of the weld layer uniform, to prevent the influence of heat on areas other than the welded part, and to prevent the occurrence of flash.
次に本発明の実施例を図に基づいて説明する。 Next, embodiments of the present invention will be described based on the drawings.

The welding member 2 is fixed to the base 20 by pressure holders 3 and 4 with its first welding surface 1a and second welding surface 2a facing each other. A predetermined interval is formed between the first welding surface 1a and the second welding surface 2a, and the thermal radiation heater 5 is arranged at this predetermined interval. The heater 5 is located exactly in the center of the predetermined gap. Note that the first welding member 1 and the second welding member 2 are welded together to form a tank.
次に第2図〜第4図に基づいて溶接の手順を説明する。Next, the welding procedure will be explained based on FIGS. 2 to 4.

The figure shows a state in which the radiant heater 5 is attached to the pressure holding jigs 3 and 4, and a state in which the temperature of the thermal radiation heater 5 is raised by the control power source 6 and the state is waiting for heating. At this time, the surface temperature of the heater 5 is measured by an infrared radiation thermometer 7, and is constantly controlled to a target value through feedbanking by a control power source 6.

In order to simultaneously melt the welding surfaces 1a and 2a to the same extent, the heater 5 is located approximately at the center of the predetermined interval 11. Next, as shown in FIG. 4, the heater 5 is removed and the pieces are quickly pressed and held using the pressure holding jigs 3 and 4 to join them. The pressing force F at this time varies depending on the material and shape of the welding member, but is 0.5 kg f~5 per 1 d of joint area of the member.
kg f is good, and holding time is good between 8 seconds and 40 seconds. Alternatively, a method of crushing to a certain size may be used. After that, the pressing and holding are released to complete the bonding.

ものではない。FIG. 5 shows another modification, in which it is also possible to weld a multi-tank having partition walls. This welding involves simultaneously welding the outer circumferential welded portions 1b and 2b of the first welded member 1 and the second welded member 2, and the partition wall portions 1c and 20. In this case, the planar shape of the thermal radiation heater 5 is preferably divided into a first heater 5a and a second heater 5b as shown in FIG. It's not something you can do.

示す形状で良く、同様に溶接が可能である。Furthermore, as another modification, it is also possible to weld a welding member that has a partial joint in addition to the outer periphery. For example, a first welding member 1 and a second welding member 2 as shown in FIG.
This is a welding of a member that has struts 1d and 2d inside. In this case, the planar shape of the heat radiator 5 may be the shape shown in FIG. 8, and welding can be similarly performed.

ある。According to the studies of the present inventors, welding is possible if the outer diameter of the welding member is up to about 50cm, the total length of the welded part is up to about 30cm, and the total welded area is up to about 200cta. However, with further research and development, it is possible to weld larger parts.
