Wiegers studied geology from 1893 in Göttingen and from 1897 in Halle, where he received his doctorate in 1899. During this time he was an assistant at the Geological Institute in Karlsruhe from 1897 to 1901. From 1901 to 1939 he was with the Prussian Geological State Institute , where he continued mapping the area around Magdeburg, which Felix Wahnschaffe and Konrad Keilhack had started. From 1944 to 1946 he was professor of prehistory in Göttingen.
His geological mapping in the area around Magdeburg provides important information about the course of the last ice age in northern and central Germany. They also led Wiegers to occupy himself with archeology and he advocated a simultaneous archaeological recording within the scope of geological mapping. This was later taken up by the State Office for Geology in Saxony-Anhalt (simultaneous mapping in the Arendsee (Altmark) area in 2000).
In 1910 he initiated the founding of the Haldensleben local history museum , where Wiegers worked together with the members of the Aller Association, particularly with the high school teacher Hans Wieprecht (1882–1966).
