Abstract
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.
