These give rise to EXC 1 (low requirements) up to EXC 4 (highest requirements). We analyse your component situation, determine the correct EXC and document the classification in conformity with standards &#8211; so that you produce neither over- nor under-classified.<\/div>\n<\/li>\n<li>\n<h3>Can you support the entire EN 1090 initial certification?<\/h3>\n<div>Yes. We handle the complete preparation: setting up the factory production control (FPC), appointing and qualifying the welding supervision (DIN EN ISO 14731), preparing WPS and WPQR, welder qualifications and preparation of the audit documents. During the audit we are on site and ensure smooth communication with the certification body (T\u00dcV, SLV, DVS-IIW).<\/div>\n<\/li>\n<li>\n<h3>What special considerations apply when welding high-strength steels such as S690QL and S960QL?<\/h3>\n<div>High-strength fine-grain structural steels react very sensitively to heat input and hydrogen absorption. The DASt Guideline 009 provides detailed specifications for preheating temperatures, heat input per unit length and post-weld heat treatment. Mistakes lead to hardening, hydrogen cracks or a drop in strength. We develop your welding instruction in conformity with standards and support the procedure qualification &#8211; so that you can realise the greater economic benefit of these steels without technical risk.<\/div>\n<\/li>\n<li>\n<h3>What is the difference between FEM 1.001 and EN 13001 for crane structures?<\/h3>\n<div>FEM 1.001 is the historically established calculation basis for lifting equipment of the FEM (F\u00e9d\u00e9ration Europ\u00e9enne de la Manutention). EN 13001 is the current European standard and increasingly the state of the art. Both work with load spectra and loading groups, but differ in detailed assessments for weld seams and fatigue. We advise on the correct application &#8211; depending on the country, client and type of structure.<\/div>\n<\/li>\n<li>\n<h3>Can you also assist with damage to existing load-bearing structures?<\/h3>\n<div>Yes. Failure analyses on crane structures and bridges are a focus of our work &#8211; crack formation, fatigue damage, corrosion damage, weld seam failure. We analyse the cause, assess the remaining load-bearing capacity and develop a repair concept &#8211; including support for the repair welding and the subsequent release documentation.<\/div>\n<\/li>\n<\/ul>\n<p><!--more--><br \/>\n<!-- {\"type\":\"layout\",\"children\":[{\"type\":\"section\",\"props\":{\"image_position\":\"center-center\",\"padding_bottom\":\"xsmall\",\"padding_top\":\"small\",\"style\":\"default\",\"title_breakpoint\":\"xl\",\"title_position\":\"top-left\",\"title_rotation\":\"left\",\"vertical_align\":\"middle\",\"width\":\"default\"},\"children\":[{\"type\":\"row\",\"children\":[{\"type\":\"column\",\"props\":{\"image_position\":\"center-center\",\"position_sticky_breakpoint\":\"m\"},\"children\":[{\"type\":\"breadcrumbs\",\"props\":{\"blend\":false,\"show_current\":true,\"show_home\":true}}]}]}],\"name\":\"1_Breadcrump\"},{\"type\":\"section\",\"props\":{\"image_position\":\"center-center\",\"overlap\":false,\"padding_bottom\":\"none\",\"padding_top\":\"none\",\"preserve_color\":false,\"style\":\"secondary\",\"title_breakpoint\":\"xl\",\"title_position\":\"top-left\",\"title_rotation\":\"left\",\"vertical_align\":\"middle\",\"width\":\"default\"},\"children\":[{\"type\":\"row\",\"children\":[{\"type\":\"column\",\"props\":{\"image_position\":\"center-center\",\"position_sticky_breakpoint\":\"m\"},\"children\":[{\"name\":\"Panel Image Right\",\"type\":\"panel\",\"props\":{\"block_align\":\"center\",\"content\":\"\n\n<p>For manufacturers and erectors of cranes, bridges and steel structures: welding consulting, welding qualification and materials consulting - in accordance with EN 1090, EN 1993, FEM and DIN 18800.
