Rezime Ovde se predstavlja poboljšanje izračunavanja veličina kod elektrolučnog zavarivanja, kao što su temperatura predgrevanja i kritičnog vremena hlađenja t 8/5. Ova istraživanja su rezultirala studiranjem teorije termike kod elektrolučnog zavarivanja i praktičnim radom, nakon čega su pronađeni načini da se rešavanje navedenih problema omogućava uvođenjem novih grafičkih i analitičkih zavisnosti. Provera navedenih rešenja je obavljena numeričkim primerima.

“…This paper also proposes a mechanism for joint formation during pressure welding. The mechanism of bonding line formation and further metallographic studies to characterize the weld seam are discussed in many other publications [ 17 , 18 , 19 , 20 , 21 , 22 ]. However, the effect of different temperatures and contact normal stresses on weld seam strength and microstructure formation in HFI welding has never been considered in a scientific publication.…”

This paper presents an experimental electro-thermo-mechanical simulation of high-frequency induction (HFI) welding to investigate the effect of temperature and contact normal stress on the weld seam quality. Therefore welding experiments at different temperatures and contact pressures are performed using flat specimens of 34MnB5 steel sheet. In order to characterize the weld seam strength of the welded specimens, tensile and bending tests are performed. To obtain a relative weld seam strength, the bending specimens were additionally hardened prior to testing. With the hardened specimens, it can be shown that the weld seam strength increases with increasing temperature and contact normal stress until a kind of plateau is formed where the weld seam strength remains almost constant. In addition to mechanical testing, the influence of the investigated process parameters on the weld seam microstructure is studied metallographically using light optical microscopy, scanning electron microscopy, EBSD and hardness measurements. It is shown that the weld seam strength is related to the amount of oxides in the bonding line.
