Abstract

The paper presents the results of the research focused on the possibility of renewal of molded parts of molds in high-pressure casting of aluminum alloys by cladding welding. Two materials - Thermanit 625 and Thermanit X - were tested. Weld-on layers were produced by CMT - Cold Metal Transfer technology in a protective atmosphere of Ar. The cllad resistance in the molten melt of the aluminum alloy EN AB AlSi8Cu3 for 120 and 300 minutes was evaluated. Furthermore, ball-on-disc wear resistance of welds was assessed. The results were compared with the reference material - AISI / SAE 309 base tool steel.
