Abstract
Over the past number of years, the Defence Research Establishment Atlantic has sponsored a number of projects aimed at evaluating welding processes suitable for the fabrication of submarines. The objective of these evaluations has been to maximize weldment toughness as determined by dynamic tear specimen testing. The Transferred Ionized Molten Energy (T.I.M.E.™) Process has emerged superior to other potential welding processes. The purpose of the present investigation was to optimize weldment properties employing the T.I.M.E.™ Process with state-of-the-art pulsing controllers and power sources. The project involved preparing welding procedures for the pulse T.I.M.E.™ Process employing a T.I.M.E. 540 power source coupled with a TR-19 synergic pulsing unit, pre-programmed for use with the patented T.I.M.E.™ Process. These procedures were first proven on mild steel before they were applied each to HY100 and HY80 steels in both the 3G (vertical down) and 1G/4G (flat/overhead) positions. A number of dynamic tear and explosion panels were prepared to evaluate the properties of the weldments. Mechanical and non-destructive test results for both HY80 and HY100 are given.
