In 1950, after falling from a ladder, Zatti began to show signs of liver cancer. He continued to work, but on March 15, 1951, at the age of 70, he died from the disease.
Artemide Zatti will be the first Salesian coadjutor to be declared a saint.
Pope Francis also advanced the beatification causes of nine other servants of God last week.
Among them are the Italian diocesan priests Giuseppe Bernardi and Mario Ghibaudo, who were killed by the Nazis in a massacre in the Italian town of Boves on Sept. 19, 1943.
Pope Francis has declared the priests, the pastor, and vice-pastor of the local parish, to be martyrs.
The Nazi massacre of Boves saw the burning of more than 300 houses, with 23 civilians killed. Boves is believed to be where the Italian Resistance originated, and the attack in September 1943 was a Nazi reprisal.
The 45-year-old Bernardi tried to mediate in the recovery of two German hostages from the Italian partisans, but the Nazis took him prisoner before killing him and burning his body.
Ghibaudo, who was 23 years old, had been a priest for only two months at the time of the massacre.
He helped the elderly flee Boves during the attack, until he was hit by machine-gun fire while giving absolution to a dying man. Ghibaudo was then also stabbed in the chest.
An Italian laywoman, Maria Aristea Ceccarelli, has also been declared venerable by Pope Francis.
