During the pulse-off period, no energy is delivered, and the nugget begins to cool and solidify. The energy delivered per pulse is the product of the peak power and the pulse duration, and this per-pulse energy is an independently adjustable parameter that allows very fine control of the thermal dose delivered to each weld location.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-12c9299 elementor-widget elementor-widget-text-editor\" data-id=\"12c9299\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\tThis contrast in energy delivery has profound practical consequences.
