Quality Control & Certification

Every TOKO welding electrode, flux cored wire and solid wire is produced inside an ISO 9001:2015 certified quality management system, independently verified by Bureau Veritas and released only after documented chemical, mechanical and welding performance testing.

Quality Commitment & Certification Excellence

TOKO's quality policy is built on defect prevention rather than defect detection — controlled raw materials, verified process parameters and complete documentation, so the electrode or wire that reaches your production line performs exactly as the certificate says it will.

Bureau Veritas & Third-Party Validation

TOKO welding electrodes have earned Bureau Veritas (BV) certification across multiple product lines, providing independent third-party validation of our chemistry, mechanical properties and welding performance. BV surveillance audits and product re-testing are carried out on a scheduled basis — so certification reflects current production, not a one-off sample.

  • ISO 9001:2015 certified production facilities with documented quality procedures
  • Continuous improvement driven by the PDCA cycle and measured quality KPIs
  • Stringent material testing: chemical, tensile, impact and radiographic checks
  • Structured operator training and qualification on welding consumable standards
  • Third-party audits plus scheduled internal quality reviews at every plant
  • Batch-level traceability from raw material heat number to finished carton

Our Quality Management Philosophy

We have built a quality management system that governs how our welding processes, products and services are designed, developed and delivered. Control points are defined at every stage — raw material intake, flux blending, extrusion, baking, winding, packing and storage — so variation is caught at the source instead of at final inspection.

TOKO continually updates its internal quality standards and strengthens its assurance structure across all manufacturing facilities, delivering reliable quality support for shipbuilding, LNG storage and containment, offshore engineering, pressure vessel fabrication, pipeline construction and heavy industry.

What Third-Party Certification Means for Your Project

Certification Benefits & Quality Validation

  • Independent verification of chemistry, mechanical properties and welding behaviour
  • Documented conformity with AWS, ISO and DIN classification requirements
  • Weld integrity confidence for critical, safety-relevant applications
  • Complete documentation packages for QA/QC and project handover
  • Worldwide acceptance of certified TOKO welding consumables

ISO 9001:2015 Quality Management System

Our ISO 9001:2015 certification covers the full welding consumables range — stick electrodes, flux cored wires, solid MIG/TIG wires and submerged arc flux — plus the packaging and storage processes that protect them in transit.

The Three-Stage Welding Consumables Inspection Process

Quality is verified at three defined gates. A batch cannot move to the next stage until the previous gate is signed off by the quality department.

Incoming Raw Material Inspection

Every delivery of core wire, steel strip, mineral powder and binder is checked against specification before it enters the production line.

  • Chemical composition verification (spectrometer analysis)
  • Wire and strip dimensional and surface checks
  • Mineral purity and moisture content testing
  • Supplier heat number recording and quarantine release

In-Process Production Control

Process parameters are monitored continuously during blending, extrusion and baking, with sampling at fixed intervals.

  • Flux blending ratio and mixing uniformity checks
  • Extrusion concentricity and coating thickness measurement
  • Baking temperature and dwell time recording
  • Moisture pickup and hydrogen content control

Finished Product Validation

Before release, each batch is subjected to destructive and non-destructive testing against its classification standard.

  • Tensile strength, yield strength and elongation testing
  • Charpy V-notch impact toughness at specified temperatures
  • Radiographic and macro-section weld soundness checks
  • Arc stability, spatter level and bead appearance evaluation

Documentation & Batch Traceability

Every batch is issued a unique number linking production data to the final test report, so any product can be traced back to its raw material heat.

  • Mill certificate (EN 10204 3.1 type) available on request
  • Batch numbers printed on coating, spool label and carton
  • Moisture-barrier packing with desiccant and re-drying instructions
  • Third-party inspection by BV, SGS or nominated surveyor

Frequently Asked Questions About Welding Quality Control

Answers to the questions our quality department receives most often from procurement teams, QA/QC managers and welding engineers.

Which certifications do TOKO welding consumables hold?

TOKO welding electrodes, flux cored wires, solid wires and submerged arc flux are produced under an ISO 9001:2015 certified quality management system. Selected product lines carry Bureau Veritas (BV) third-party certification, and our consumables are manufactured to AWS, ISO and DIN classifications including AWS A5.1 E6013, A5.1 E7018, A5.4 E309L/E316L, A5.20 E71T-1C and A5.10 ER5356.

How does TOKO control welding electrode quality during production?

Quality control runs across three gates. Incoming inspection verifies the chemical composition and dimensions of core wire, strip and coating minerals. In-process checks monitor flux blending ratios, extrusion concentricity, coating thickness, baking temperature and moisture pickup. Finished goods are then tested for chemical composition, tensile strength, yield strength, elongation, impact toughness, radiographic soundness and arc stability before release.

Can TOKO supply a mill certificate or third-party inspection report with an order?

Yes. Every shipment can be accompanied by a mill certificate (EN 10204 3.1 type) documenting heat number, chemical analysis and mechanical properties. We also support third-party inspection by Bureau Veritas, SGS, TUV or your nominated surveyor, and can provide welding procedure qualification support on request.

Which welding products are covered by TOKO's ISO 9001:2015 system?

The scope covers stick electrodes (E6013, E6011, E7018, E308L, E309L, E316L and low-alloy types), flux cored wires (E71T-1C, E71T-1M, E70C-6M), solid MIG/TIG wires (ER70S-6, ER5356, ER5183) and submerged arc welding flux — together with the packaging and warehousing processes that protect them.

How does TOKO guarantee traceability and shelf life of welding consumables?

Each batch is assigned a unique batch number linked to raw material heat numbers, production line, baking cycle, operator record and final inspection data. Batch numbers are printed on the electrode coating, wire spool label and carton. Products are vacuum or moisture-barrier packed with desiccant, and a re-drying instruction is supplied so you can restore low-hydrogen electrodes to specification before use.
