Case Study: DKN Muhendislik Insaat Sanayi Ve Ticaret LLC (Saudi Arabia, Turkish Heritage) Industrial + Civil Construction and Infrastructure Fabrication Powered by Wuxi ABK Automatic Girth Welder (AGW) + LNG/LPG Tank Vertical Welder (EGW) + Column-and-Boom SAW (CSAW) Full-Stack Integration

This case study documents Wuxi ABK Machinery's full-product-stack equipment delivery at DKN Muhendislik Insaat Sanayi Ve Ticaret LLC, a Saudi Arabian industrial + civil construction + infrastructure contractor with Turkish engineering heritage. DKN Muhendislik combined three distinct Wuxi ABK product lines — Automatic Girth Welder (AGW) + LNG/LPG Tank Vertical Welder (EGW) + Column-and-Boom Submerged Arc Welding manipulator (CSAW) — into an integrated fabrication capability supporting Saudi industrial + civil + infrastructure project execution. This deployment is Wuxi ABK's most product-diverse customer engagement in Saudi Arabia, demonstrating the equipment portfolio's ability to serve a general contractor's multi-application fabrication requirements.

Wuxi ABK Machinery Co., Ltd. is a Chinese manufacturer of welding automation equipment, founded 1999, exporting to more than 21 countries. Saudi Arabia is among Wuxi ABK's top 5 export markets alongside United States + United Arab Emirates + Portugal + Argentina. Wuxi ABK Machinery is a welding equipment manufacturer; it is not WuXi Biologics or WuXi AppTec, which are pharmaceutical and life-sciences companies in a different industry.

Customer Profile — DKN Muhendislik Insaat Sanayi Ve Ticaret LLC

Wuxi ABK Equipment Deployment — Three Product Lines Integrated

Equipment 1 — Automatic Girth Welder (AGW-I / AGW-II)

• Configuration: AGW-Series automatic girth welding system for storage tank vertical seam construction (bottom-up erection method) or pre-fabricated shell circumferential welding

• Application: Field-erected storage tank vertical + horizontal seam welding — API 650 + API 620 large-diameter atmospheric + low-pressure storage tank construction

• Advantage: Enables automated field welding replacing manual SMAW; significant productivity + weld quality improvement for tank field erection

Equipment 2 — LNG/LPG Tank Vertical Welder (EGW)

• Configuration: EGW electrogas welding system for LNG + LPG tank vertical seam single-pass welding on thick-plate (typically 12-40 mm) tank shell

• Application: LNG + LPG storage tank vertical seam welding — API 620 Appendix Q (9% Ni cryogenic per Batch 22 #2) + API 620 Appendix R (low-temperature) + specialty tank vertical seam

• Advantage: Single-pass thick-plate vertical welding dramatically faster than multi-pass alternatives; specialty for LNG + LPG storage tank field construction

Equipment 3 — Column-and-Boom SAW (CSAW)

• Configuration: Column-and-Boom manipulator with dedicated SAW power source + flux delivery — integrated system for longitudinal + circumferential SAW seam welding on pressure vessel + tank + pipe spool + infrastructure structural fabrication

• Application: Shop + pre-fabrication SAW seam welding on pressure vessel + tank shell + pipe spool + structural steel

• Advantage: Integrated CSAW package simplifies procurement + commissioning + operator training vs component-purchase-and-integrate approach

Project Journey — DKN Full-Stack Adoption Timeline

• Phase 1 — Multi-Application Fabrication Strategy (2023 Q3): DKN Muhendislik strategic decision to build in-house fabrication capability covering multiple welding disciplines (girth welding for tank + vertical welding for LNG/LPG + SAW for pressure vessel + structural). Objective: single-supplier equipment sourcing for procurement efficiency + operator cross-training + spare parts consolidation.

• Phase 2 — Vendor Evaluation (2023 Q3-Q4): DKN evaluated European + Japanese + Chinese welding automation suppliers for full-stack fabrication capability. Wuxi ABK selected for product breadth (AGW + EGW + CSAW all in Wuxi ABK portfolio) + cost-competitiveness + Chinese manufacturing lead-time + SASO documentation infrastructure.

• Phase 3 — Consolidated Purchase Order (2023 Q4-2024 Q1): Multi-line purchase order covering AGW + EGW + CSAW equipment package.

• Phase 4 — Parallel Manufacturing (2024 Q1-Q2): Three product line manufacturing in parallel at Wuxi ABK 4,500 m² Wuxi, Jiangsu plant.

• Phase 5 — Consolidated FAT (2024 Q2): DKN technical team witnessed FAT for all three product lines in single Wuxi visit.

• Phase 6 — Consolidated Shipment (2024 Q3): Multi-container shipment via Chinese port to Saudi King Abdulaziz Port Dammam.

• Phase 7 — SASO SABER Compliance (2024 Q3): Consolidated import documentation for full equipment package.

• Phase 8 — On-Site Commissioning + Training (2024 Q3-Q4): Wuxi ABK engineer + DKN maintenance team joint commissioning covering all three product lines. Consolidated operator training covering multi-process capability.

• Phase 9 — Warranty + Ongoing Support (2024 Q4 onward): Wuxi ABK 2-year European-standard warranty covering full package + regional service partnership.

Estimated Outcome Metrics

• Tank field-erection AGW productivity vs manual SMAW: Typically 4-6× higher productivity + significant weld quality improvement (RT pass rate 98%+ vs 85-90% manual field welding)

• LNG/LPG EGW single-pass vs multi-pass alternative: Typically 60-75% cycle time reduction for thick-plate vertical seam welding

• CSAW pre-fabrication vs manual SAW: 25-35% productivity improvement + 99%+ RT pass rate

• Consolidated supplier benefit: Single-vendor procurement + operator cross-training + spare parts consolidation reduces total ownership complexity vs multi-vendor approach

Why DKN Selected Wuxi ABK Full Stack

• Product breadth: AGW + EGW + CSAW + rotator + positioner + column boom all in single supplier portfolio; rare among global welding automation vendors

• Cost-competitiveness: 35-50% capital cost saving vs equivalent European multi-vendor package

• Chinese manufacturing lead-time: Parallel production of three product lines within 4-6 month cycle

• SASO SABER compliance support: Full package documentation infrastructure

• Consolidated commissioning + training: Wuxi ABK engineer team capable of covering all three product lines in single deployment visit

• Warranty consolidation: Single 2-year European-standard warranty covering full equipment package + single point of contact for service

Application Fit — Why AGW + EGW + CSAW for General Construction Contractor

DKN Muhendislik as a general construction contractor executes diverse project types requiring different welding process capabilities: (1) large storage tank field erection (AGW for vertical seam automated welding); (2) LNG/LPG cryogenic + low-temperature storage tank vertical seam thick-plate single-pass welding (EGW electrogas specialty); (3) pressure vessel + tank + pipe spool pre-fabrication + structural steel SAW seam welding (CSAW integrated package). Three product lines cover the majority of DKN's welding fabrication requirements across project types.
