A method of provisionally joining livestock tag parts, where the tag parts (1a-c, 7a-c) are welded together by ultrasonic welding without added materials. The tag parts (1a-c, 7a-c) are provided with raised portions (4, 5) that ensure a predictable resistance to breaking. The tag parts (1a-c, 7a-c) are arranged to overlap and form a strip.
