To overcome\r\nthermal imbalance constraints, an innovative strategy leveraging plastic shell containment is proposed to elevate\r\nthe expulsion-free heat input threshold. By applying a combined preheating and ramping current profile, a coordinated “shell-first, nugget-second” sequence is achieved. This mechanism creates a solid-state barrier prior to\r\nrapid fusion, effectively preventing expulsion. Experimental results demonstrate that while the reference\r\nconstant-current schedule fails to maintain a process window under a 2 mm initial gap (IG) disturbance, the\r\nproposed strategy significantly enhances process stability. It increases the maximum expulsion-free heat input by\r\n24 % (to 6338 J) under normal conditions and by 77 % (to 6482 J) under the IG condition. Crucially, the\r\nincreased heat input drives nugget growth across all interfaces, achieving a penetration depth of 0.38 mm (48 %\r\npenetration ratio) in the low-carbon steel sheet under the gap condition. These findings validate the strategy’s\r\neffectiveness in ensuring weld quality and robustness, which is further confirmed by its transferability to a lowerresistivity DX54D cover sheet.","lang":"eng"}],"publication":"Journal of Manufacturing Processes"}]
