Possibilities with Use of Electron Beam Welding of Very High Strength Steel

Abstract:

Welding of very high strength quenched and tempered steel, R_p0.2≥ 900 MPa, put high demands on choice of welding process, consumables and also on the heat input. Such steels commonly have a quite narrow tolerance box for a suitable weld heat input to control the cooling time, Δt_8/5, pertaining to minimize the risk for generating weld defects such as undercut, a too soft weld heat affected zone, delayed cracking etc. When welding very high strength steel is the risk for cold cracking in the weld metal not negligible due to the high alloy content of such high strength filler wires used. Furthermore, filler metal wires having equal strength levels to very high strength steel are hard to find which, together with the above described drawbacks, favour use of under-matching filler wires.
