Abrégé

An exothermic welding cup and an exothermic welding capsule, wherein the exothermic welding cup comprises a cup, a cover and an igniter; the cup is used to accommodate welding powder, the cup has an opening, and the cover is used to cover the opening; the igniter comprises a heating portion disposed in the cup, and the heating portion has an insulating member and a heating member; and the insulating member is disposed between the heating member and the cover. The exothermic welding cup can avoid the shorting caused by the contact between the heated heating member and the cover. Also, an encapsulation ring disposed between the cover and the cup is configured to seal the welding powder within the cup so as to prevent the powder from falling out, and the encapsulation ring made of stainless steel ensures effective encapsulation of the welding powder within a certain welding time.

Abrégé

An exothermic welding cup and an exothermic welding capsule, belonging to the field of exothermic welding tools, wherein the exothermic welding cup (010) comprises a cup body (100), a cover body (200) and an igniter (300); the cup body (100) is used for accommodating welding powder, the cup body (100) has an opening (110), and the cover body (200) is used for covering the opening (110); the igniter (300) comprises a heat generating portion (310); the heat generating portion (310) is disposed inside of the cup body (100), and the heat generating portion (310) comprises an insulating member (313) and a heat generating member (311); the insulating member (313) is disposed between the heat generating member (311) and the cover body (200). Short circuiting due to a heat generating member touching a cover body when generating heat may be avoided by means of the exothermic welding cup. In addition, a encapsulation ring (210) is also provided between the cover body (200) and the cup body (100) for encapsulation; the powder may be prevented from falling out by means of the encapsulation ring encapsulating the welding powder within the cup body; moreover, in an actual welding process, the encapsulation ring made from stainless steel does not fail easily, and may ensure that the welding powder within the cup body may also be effectively encapsulated within a certain welding time.
