Snow chains manufacturing
Bořek, Pavel ; Kubíček, Jaroslav (referee) ; Císařová, Michaela (advisor)
This thesis is aimed at investigating the snow chain manufacturing process with a closer focus on the problematic spot related to the heat affected zone, weld and base metal. In the theoretical part, the issue of resistance welding and the metallurgical processes involved in the formation of a resistance weld are described for a better understanding of the nuances in the practical part where a structural analysis of the weld area in terms of microstructure, macrostructure and hardness is carried out. For this part, chain samples after welding, carburizing, quenching, tempering and zinc electroplating are used.
