ABSTRACT:
The method of electric-arc condenser-discharge percussion stud welding includes prepositioning a stud on an article, retracting the stud from the article while igniting an auxiliary arc between them, and moving the stud towards the article. While the stud is thus moved, the voltage drop across the auxiliary electric arc is measured, and from the value thus measured is subtracted the sum of electrode-adjoining voltage drops at the end of the stud and at the article, and when the voltage drop value thus obtained varies by 10 to 90 percent from the initially obtained value of the voltage drop, the discharge of the condenser is initiated. Then the stud is introduced into the molten metal of the article, and the end of the stud is butted with the article to form a welded joint.
