Welding method in forming process of contact

The invention discloses a welding method in a forming process of a contact, which comprises the following steps of: S1, preparing powder: sequentially putting contact powder of a conductive part and a silver-based electrical contact into a mold to obtain a flash-burning mold; s2, flash burning: the flash burning mold is put into a sintering furnace for primary flash burning, and a whole contact is obtained; s3, machining is conducted, specifically, turning is conducted on the whole contact obtained in the step S2; the contact powder and the conductive part are connected together in the powder forming process to form the contact conductive part, the contact conductive part is suitable for fixing the contact on the conductive part, the follow-up welding or using performance is not affected, the solder of a contact metal coating can be prevented from climbing deep, and the contact quality is improved. And the welding structure can overcome the problems of poor exhaust in the existing welding process, insufficien
