After a welding time of just 1-3 ms and a welding current of up to 15,000A, the stud and base material are homogeneously bonded and only have a very small melting zone of a few tenths of a millimeter. This allows studs to be welded to very thin sheets without annoying markings or discolouration becoming visible on the back.”][tm_spacer size=”lg:50″][\/vc_column_inner][\/vc_row_inner][\/vc_column][vc_column width=”1\/2″ background_color=”custom” offset=”vc_col-lg-3″ custom_background_color=”#303d43″][tm_image full_wide=”1″ custom_border_color=”” image=”3117″][\/vc_column][vc_column width=”1\/2″ background_color=”primary” offset=”vc_col-lg-3″][vc_row_inner lg_spacing=”padding_right:80;padding_left:80″ md_spacing=”padding_right:70;padding_left:70″ sm_spacing=”padding_top:100;padding_right:50;padding_bottom:100;padding_left:50″ xs_spacing=”padding_top:100;padding_right:30;padding_bottom:100;padding_left:30″][vc_column_inner][tm_heading custom_google_font=”” text=”The splitting process” font_size=”lg:40″][tm_spacer size=”lg:35″][tm_heading tag=”div” custom_google_font=”” text_color=”custom” custom_text_color=”rgba(0,0,0,0.48)” text=”The gap method differs from the contact method in that after the button is pressed, the bolt is lifted by a lifting magnet in the gun to a preset stroke or gap and then accelerated towards the workpiece by spring force. The arc ignites as soon as the firing tip of the stud touches the workpiece. The arc burning time or welding time can be changed by adjusting the gap size; however, this is generally shorter than with the contact method. The splitting process is therefore preferred for materials with a low melting point, such as aluminum or brass. The welding time is a maximum of 1.5 ms and the melting zone is even smaller than with the contact method. However, even more attention must be paid to a clean workpiece surface, which must be free of galvanic coatings, oil, rust or scale.”][tm_spacer size=”lg:50″][\/vc_column_inner][\/vc_row_inner][\/vc_column][vc_column width=”1\/2″ background_color=”custom” offset=”vc_col-lg-3″ custom_background_color=”#303d43″][tm_image full_wide=”1″ image=”3131″][\/vc_column][\/vc_row][vc_row][vc_column][tm_table][\/tm_table][\/vc_column][\/vc_row][vc_row][vc_column][tm_table][\/tm_table][\/vc_column][\/vc_row]","og_url":"https:\/\/www.stud-welding.de\/en\/strength-values\/","og_site_name":"Bolzenschwei\u00dftechnik BSK + BTV GmbH","article_modified_time":"2025-05-22T13:40:40+00:00","twitter_card":"summary_large_image","twitter_misc":{"Est. reading time":"4 minutes"},"schema":{"@context":"https:\/\/schema.org","@graph":[{"@type":"WebPage","@id":"https:\/\/www.stud-welding.de\/en\/strength-values\/","url":"https:\/\/www.stud-welding.de\/en\/strength-values\/","name":"strength values - Bolzenschwei\u00dftechnik BSK + BTV GmbH","isPartOf":{"@id":"https:\/\/www.stud-welding.de\/#website"},"datePublished":"2021-07-05T15:23:48+00:00","dateModified":"2025-05-22T13:40:40+00:00","inLanguage":"en-US","potentialAction":[{"@type":"ReadAction","target":["https:\/\/www.stud-welding.de\/en\/strength-values\/"]}]},{"@type":"WebSite","@id":"https:\/\/www.stud-welding.de\/#website","url":"https:\/\/www.stud-welding.de\/","name":"Bolzenschwei\u00dftechnik BSK + BTV GmbH","description":"Bolzenschwei\u00dftechnik aus Massenbachhausen","potentialAction":[{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https:\/\/www.stud-welding.de\/?s={search_term_string}"},"query-input":{"@type":"PropertyValueSpecification","valueRequired":true,"valueName":"search_term_string"}}],"inLanguage":"en-US"}]}},"_links":{"self":[{"href":"https:\/\/www.stud-welding.de\/en\/wp-json\/wp\/v2\/pages\/5445","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.stud-welding.de\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.stud-welding.de\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.stud-welding.de\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.stud-welding.de\/en\/wp-json\/wp\/v2\/comments?post=5445"}],"version-history":[{"count":1,"href":"https:\/\/www.stud-welding.de\/en\/wp-json\/wp\/v2\/pages\/5445\/revisions"}],"predecessor-version":[{"id":5448,"href":"https:\/\/www.stud-welding.de\/en\/wp-json\/wp\/v2\/pages\/5445\/revisions\/5448"}],"wp:attachment":[{"href":"https:\/\/www.stud-welding.de\/en\/wp-json\/wp\/v2\/media?parent=5445"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
