1/2 Inch Model Metal (LTF) Experimentally Welded H-Beam

摘要

This report covers the construction, heat treatment, and test of a welded H-Beam of 1/2 Monel metal plate (LTF). The H-Beam was completely assembled and tack welded together before welding was started. There was no machined fit between any of the parts. The tack welds were placed at the ends of the web and at the ends of the legs of the triangular flange stiffeners. Welding was performed with a Monel electrode (Inco no. 130-X). It is significant that even though the weld fillets have been bent and stretched longitudinally and transversely, there is no evidence of weld failure.
