The standard governs the entire execution chain \u2014 from welding procedure qualification through factory production control, welder certification, NDT requirements, and CE Marking of finished steel components. Welding equipment plays a supporting role in this chain, and equipment with traceable documentation packages materially simplifies a fabricator&#8217;s EN 1090 qualification process.<\/p>\n<p>This guide walks through how welding equipment supports EN 1090 compliance for European structural steel fabricators, the documentation chain Wuxi ABK Machinery provides, and the common procurement pitfalls fabricators face when sourcing welding equipment for Execution Class 2 (EXC2), 3 (EXC3), and 4 (EXC4) work. Framework based on Wuxi ABK&#8217;s experience supplying welding equipment to European-market fabricators since 1999 \u2014 21+ countries delivered, top markets USA, Saudi Arabia, UAE, Portugal, Argentina, with active European footprint across Spain, Germany, France, Italy, Portugal, Russia, Poland, and the United Kingdom.<\/p>\n<h2>EN 1090 Standard Family at a Glance<\/h2>\n<p>EN 1090 is a family of European standards published by CEN governing the execution of structural steel and aluminum components and their CE Marking under the Construction Products Regulation (CPR, EU 305\/2011).<\/p>\n<table border=\"1\" cellpadding=\"6\" cellspacing=\"0\">\n<thead>\n<tr>\n<th>Standard<\/th>\n<th>Scope<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>EN 1090-1<\/strong><\/td>\n<td>Conformity assessment requirements for structural components \u2014 CE Marking framework<\/td>\n<\/tr>\n<tr>\n<td><strong>EN 1090-2<\/strong><\/td>\n<td>Technical requirements for execution of steel structures<\/td>\n<\/tr>\n<tr>\n<td><strong>EN 1090-3<\/strong><\/td>\n<td>Technical requirements for execution of aluminum structures<\/td>\n<\/tr>\n<tr>\n<td><strong>EN 1090-4<\/strong><\/td>\n<td>Technical requirements for cold-formed structural steel components<\/td>\n<\/tr>\n<tr>\n<td><strong>EN 1090-5<\/strong><\/td>\n<td>Technical requirements for cold-formed structural aluminum components<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The EN 1090-2 (steel structures) is the standard most directly relevant to welding equipment selection for heavy fabrication.<\/p>\n<h2>Execution Classes EXC1 \u2014 EXC4<\/h2>\n<p>EN 1090-2 classifies structural steel execution by consequence of failure into four execution classes:<\/p>\n<table border=\"1\" cellpadding=\"6\" cellspacing=\"0\">\n<thead>\n<tr>\n<th>Execution Class<\/th>\n<th>Typical Application<\/th>\n<th>Welding Procedure Rigor<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>EXC1<\/strong><\/td>\n<td>Low-consequence buildings (small residential, agricultural sheds)<\/td>\n<td>Minimal \u2014 simple welding procedures<\/td>\n<\/tr>\n<tr>\n<td><strong>EXC2<\/strong><\/td>\n<td>Standard buildings, light pedestrian bridges, light road bridges<\/td>\n<td>Standard \u2014 qualified WPS, qualified welders<\/td>\n<\/tr>\n<tr>\n<td><strong>EXC3<\/strong><\/td>\n<td>Office \/ commercial multi-story buildings, standard road bridges<\/td>\n<td>Higher \u2014 WPS qualification per ISO 15614, welder qualification per ISO 9606, NDT for critical welds<\/td>\n<\/tr>\n<tr>\n<td><strong>EXC4<\/strong><\/td>\n<td>Railway bridges, critical infrastructure, high-consequence structures<\/td>\n<td>Highest \u2014 full WPS \/ PQR \/ NDT chain, welding coordinator per ISO 14731<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For wind tower bases (offshore + onshore), heavy industrial steel structures, and bridge engineering projects, EXC3 and EXC4 are the typical specified classes.<\/p>\n<h2>Welding Equipment Role in EN 1090 Compliance<\/h2>\n<p>The welding equipment supplier does NOT certify the fabricator&#8217;s EN 1090 status \u2014 that certification is held by the structural steel fabricator and audited by a Notified Body. However, welding equipment supports compliance through five mechanisms:<\/p>\n<h3>1. Documentation Chain Integrity<\/h3>\n<p>Welding equipment shipped with traceable certificates, serial numbers, and welding parameter operating ranges enables the fabricator to demonstrate equipment suitability in WPS qualification.<\/p>\n<p>Wuxi ABK Machinery ships every welding equipment unit with:<\/p>\n<ul>\n<li>CE Marking under Machinery Directive 2006\/42\/EC<\/li>\n<li>EU Declaration of Conformity (DoC)<\/li>\n<li>SGS independent third-party inspection certification<\/li>\n<li>Unique identification code for lifecycle traceability (manufacturing batch, outgoing inspection record, installation team, post-sale service log)<\/li>\n<li>Welding parameter operating range documentation (welding speed, current, voltage, duty cycle)<\/li>\n<li>Technical Documentation File available on request<\/li>\n<\/ul>\n<h3>2. Welding Procedure Qualification Support (ISO 15614)<\/h3>\n<p>EN 1090-2 references ISO 15614 for welding procedure qualification (WPQR). For each Welding Procedure Specification (WPS), the fabricator runs a Procedure Qualification Record (PQR) test against the qualified parameter range. Wuxi ABK provides:<\/p>\n<ul>\n<li>Detailed welding parameter operating range documentation per equipment type<\/li>\n<li>Standards alignment references (production aligned with AWS D1.1 structural welding code and ISO 3834 fusion welding quality requirements)<\/li>\n<li>Welding parameter capture capability (on advanced equipment such as TTW-300 \/ TTW-500 Tube-to-Tube Welding Machines with 200+ preset welding programs)<\/li>\n<\/ul>\n<h3>3. Welder Qualification Equipment Suitability (ISO 9606)<\/h3>\n<p>ISO 9606 welder qualification tests are run on equipment whose parameter range supports the qualification scope. Wuxi ABK welding rotators, manipulators, and positioners support fabricator&#8217;s welder qualification work across:<\/p>\n<ul>\n<li>Submerged Arc Welding (SAW) \u2014 for heavy-section structural steel<\/li>\n<li>Gas Metal Arc Welding (MAG \/ MIG) \u2014 for mid-thickness structural steel<\/li>\n<li>Flux-Cored Arc Welding (FCAW) \u2014 for outdoor heavy fabrication<\/li>\n<li>Gas Tungsten Arc Welding (TIG) \u2014 for high-precision structural connections<\/li>\n<\/ul>\n<h3>4. Equipment Suitable for EN 1090 Structural Welding<\/h3>\n<p>Wuxi ABK&#8217;s heavy fabrication welding equipment portfolio supports EN 1090 EXC2 \/ EXC3 \/ EXC4 structural welding:<\/p>\n<ul>\n<li><strong>HGZ \/ HGK \/ HJK Welding Rotators<\/strong> \u2014 for cylindrical structural components (wind tower sections, pressure vessels)<\/li>\n<li><strong>LH-3030 \/ LH-3040 \/ LH-8080 \/ LH-80150 Column-and-Boom Manipulators<\/strong> \u2014 for circumferential and longitudinal seam welding on heavy steel structures<\/li>\n<li><strong>HBJ Welding Positioners<\/strong> (HBJ-03 \/ 06 \/ 12 \/ 20 \/ 30 \/ 50 \/ 100) \u2014 for component-level structural welding<\/li>\n<li><strong>3-Stage H-Beam Welding Line<\/strong> (assembly + welding + flange straightening) \u2014 for H-beam structural steel production<\/li>\n<li><strong>Submerged Arc Welding Tractor<\/strong> \u2014 for fillet welds on heavy structural steel<\/li>\n<\/ul>\n<h3>5. Equipment CE Marking Supports \u2014 But Does NOT Constitute \u2014 Fabricator EN 1090 Certification<\/h3>\n<p>This is the most important point in European structural steel procurement. <strong>Equipment CE Marking under Machinery Directive 2006\/42\/EC and finished structural component CE Marking under EN 1090-1 are separate certifications:<\/strong><\/p>\n<table border=\"1\" cellpadding=\"6\" cellspacing=\"0\">\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Held By<\/th>\n<th>Verification<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Welding equipment CE Marking<\/td>\n<td>Equipment manufacturer (Wuxi ABK)<\/td>\n<td>Machinery Directive 2006\/42\/EC + EU DoC + NANDO database<\/td>\n<\/tr>\n<tr>\n<td>Welding equipment SGS certification<\/td>\n<td>Third-party inspector<\/td>\n<td>SGS test reports<\/td>\n<\/tr>\n<tr>\n<td>EN 1090 Welding Procedure Specification (WPS \/ PQR)<\/td>\n<td>Fabricator<\/td>\n<td>ISO 15614 procedure qualification<\/td>\n<\/tr>\n<tr>\n<td>EN 1090 Welder Qualification<\/td>\n<td>Fabricator<\/td>\n<td>ISO 9606 welder qualification<\/td>\n<\/tr>\n<tr>\n<td>EN 1090 Welding Coordinator<\/td>\n<td>Fabricator<\/td>\n<td>ISO 14731 welding coordinator certificate<\/td>\n<\/tr>\n<tr>\n<td>Factory Production Control (FPC)<\/td>\n<td>Fabricator<\/td>\n<td>EN 1090-1 FPC audit by Notified Body<\/td>\n<\/tr>\n<tr>\n<td>EN 1090 EXC Certification<\/td>\n<td>Fabricator<\/td>\n<td>Notified Body audit + certificate issuance<\/td>\n<\/tr>\n<tr>\n<td>CE Marking of finished steel component<\/td>\n<td>Fabricator<\/td>\n<td>EN 1090-1 conformity assessment<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>For European structural steel fabricators sourcing welding equipment from Wuxi ABK, the equipment&#8217;s documentation chain (CE Marking + SGS) supports the fabricator&#8217;s EN 1090 qualification but does not substitute for it. The fabricator maintains its own ISO 15614 WPS qualification, ISO 9606 welder qualification, and EN 1090-1 Factory Production Control audit using the equipment.<\/p>\n<h2>Common European Procurement Pitfalls<\/h2>\n<h3>Pitfall 1 \u00b7 Confusing Equipment CE with Structural Component CE<\/h3>\n<p>Some procurement teams assume CE-marked welding equipment automatically delivers CE-marked structural steel components. The structural steel component requires separate CE Marking under EN 1090-1, held by the fabricator after Notified Body audit. Equipment CE supports but does not constitute structural component certification.<\/p>\n<h3>Pitfall 2 \u00b7 Missing or Incomplete Equipment Documentation<\/h3>\n<p>A welding equipment supplier without complete EU Declaration of Conformity creates documentation chain gaps that the fabricator&#8217;s Notified Body may flag during EN 1090 FPC audit. Verify supplier&#8217;s Notified Body accreditation via the EU NANDO database (https:\/\/ec.europa.eu\/growth\/tools-databases\/nando\/) before equipment shipment.<\/p>\n<h3>Pitfall 3 \u00b7 Equipment Not Aligned to Fabricator&#8217;s Execution Class<\/h3>\n<p>EXC4 (railway bridges, critical infrastructure) requires welding equipment supporting full traceability \u2014 every weld linked to qualified WPS + qualified welder + parameter capture. EXC1 \/ EXC2 fabrication is less demanding. Match equipment capability and documentation chain depth to your execution class. Wuxi ABK welding parameter range documentation supports EXC2 \/ EXC3 \/ EXC4 traceability.<\/p>\n<h3>Pitfall 4 \u00b7 Lost WPS \/ PQR \/ Welder Qualification Records<\/h3>\n<p>For multi-year European structural steel fabrication operations, maintain WPS \/ PQR (ISO 15614) and welder qualification records (ISO 9606) cross-referenced with welding equipment serial numbers. Lost records require re-qualification under fabricator cost during the next Notified Body audit.<\/p>\n<h3>Pitfall 5 \u00b7 Welding Coordinator Coverage Gap (ISO 14731)<\/h3>\n<p>EXC3 and EXC4 require a designated welding coordinator (Responsible Welding Coordinator, RWC) per ISO 14731. The RWC holds personal certification covering the welding processes and execution class scope. Welding coordinator scope changes when new welding equipment introduces a new welding process \u2014 confirm coordinator certification covers the new equipment&#8217;s process scope.<\/p>\n<h2>Real Customer Deployments<\/h2>\n<p>Wuxi ABK welding equipment is deployed by international heavy-fabrication customers, including:<\/p>\n<ul>\n<li><strong>ATECO GLOBAL INDUSTRIAL CO., LTD<\/strong> (Turkey-headquartered, Saudi Arabia operations) \u2014 storage tank systems, aluminum geodesic domes, internal floating roofs, sealing systems; deployed Wuxi ABK welding rotator + column-and-boom manipulator + welding positioner combination<\/li>\n<li><strong>AL ZAMIL HEAVY INDUSTRIES LTD<\/strong> (Saudi Arabia) \u2014 pressure vessels, heat exchangers, industrial cranes; deployed Wuxi ABK column-and-boom manipulator<\/li>\n<li><strong>DKN MUHENDISLIK INSAAT SANAYI VE TICARET LLC<\/strong> (Saudi Arabia) \u2014 engineering and construction; deployed Automatic Girth Welder + Electrogas Welder + submerged arc welding equipment<\/li>\n<li><strong>ELCO INTERNATIONAL ENGINEERING CO.
