Frequently Asked
Questions.

The most common questions about certifications, quality processes, welding methods and logistics.

G.01

General & Competence

Q·01

What information do you need from us for a quote?

For us to provide a fast and accurate quote, three pieces of information are critical:

  • Technical drawing — 2D (DXF/DWG/PDF) or 3D (STEP) — for extracting WPS and material lists
  • Tolerance class — such as ISO 13920 BE/CG — tolerances directly affect production process and cost
  • Target delivery date and quantity — for capacity planning

If there are no drawings, no problem — we can start from a sample or photo and reverse-engineer.

Q·02

How long does a quote take?

For standard component quotes we target a response within 48 hours. For complete structures or PED/CE pressure equipment this can extend to 5 – 7 business days — because we deliver calculations, WPS and NDT plans together with the quote.

Q·03

Is there a minimum order quantity?

No. We produce both single-part prototypes and 1,000-unit series. However, working at MOQ=1 reflects the entire setup cost onto a single part — we state this transparently from the outset.

Q·04

What if there are no drawings — can you work from a sample?

Yes. Under reverse engineering we model the sample with a 3D scanner or manual measurement and produce the manufacturing drawing. After your approval we proceed to production. We also deliver the drawing files to the customer during this process.

Q·05

What are the payment terms?

For first orders we generally work with 40% advance + 60% before shipment. For continuing customers we open term accounts or open accounts secured by bank guarantee letters. International orders have L/C or T/T options.

G.02

Quality & Documentation

Q·06

What quality certifications do you hold?

Actively held certifications:

  • ISO 9001 Quality Management System
  • ISO 14001 Environmental Management System
  • ISO 45001 Occupational Health & Safety Management System
  • EN ISO 3834-2 Welded fabrication comprehensive quality requirements
  • EN 1090-2 EXC3 Structural steel fabrication and CE marking

In addition, production is carried out in compliance with PED 2014/68/EU and EN 15085-2 requirements.

For each certification we can share the current certificate file in the quote or upon request.

Q·07

Is NDT (non-destructive testing) done in-house?

VT (visual), PT (penetrant), MT (magnetic particle) and UT (ultrasonic) inspections are performed in-house by our EN ISO 9712 Level II certified personnel. Only RT (radiography) requires a radiation licence and is performed by our authorised laboratory partner — in either case we deliver the full report chain to the customer.

Q·08

Do you provide material certificates (3.1 / 3.2)?

Yes. By default, EN 10204 3.1 material certificates are added to all projects. For PED scope or special customer requests, 3.2 certificates (independent inspection body approved) are obtained. Optional PMI (Positive Material Identification) testing verifies material grade before site work.

Q·09

How do you handle third-party inspection?

If the customer requests, we invite an accredited third-party inspection body (notified body) to our factory and have witness inspections performed at the WPQR, FAT (Factory Acceptance Test), NDT and dimensional control stages. These reports are delivered to the customer in the Final Documentation Dossier.

Q·10

How does the traceability chain work?

We assign each material part a unique HEAT / LOT number. This number is chained through cutting, welding, painting and shipping in our system — so even 10 years later you can query, by file number, with which WPS, by which welder (WPQ) and on what material a given weld was made.

G.03

Welding & Production

Q·11

Which welding processes do you use?

We routinely use the MAG (135/138), TIG (141), MMA (111) and Submerged Arc (SAW, 121) processes. We have approved WPS and pWPS portfolios for each. Selection is made by our welding engineer based on material, thickness, position and quality class.

Q·12

Are your welders certified?

All welders working in-house are certified to EN ISO 9606-1. Certificates are filed by process, material group, thickness and position; reviewed every 6 months and renewed by re-examination every 2 years. WPQ records can be delivered with the project documentation.

Q·13

Can you perform heat treatment (PWHT)?

Yes — we have a calibrated stress-relief furnace in-house. Temperature and time records are taken automatically by chart recorder + digitally and filed. We also offer mobile PWHT service for large equipment.

Q·14

Is there a separate workshop for stainless steel fabrication?

Yes. We operate two physically separated workshops for carbon steel and stainless steel — no shared equipment, even welding torches, grinding wheels, brushes and gloves are colour-coded. This discipline reduces galvanic contamination risk to zero.

Q·15

Can you process ultra-high-strength steel like S960QL or Strenx 960/1100?

Yes. S960QL (fy ≥ 960 MPa) is a quenching & tempering (QT) treated steel and requires special precautions in welding. At ArmaWeld for this material:

  • An EN ISO 15614-1-based, S960QL-specific approved WPS is used — a generic WPS is not valid
  • Preheat is calculated according to carbon equivalent (CEV) using EN 1011-2 Method B
  • Interpass temperature is measured and recorded — preventing hardness loss is critical
  • Low-hydrogen consumables (H5 class or below) are mandatory

Working with this steel requires procedural discipline as much as technical capability. If your project includes S960QL, please indicate it in advance — we can share our WPS portfolio.

Q·16

What is the welding difference between S700MC and S690QL?

Both are high-strength steels but their production methods differ, which fundamentally changes the welding approach:

  • S700MC — TMCP (Thermomechanically Controlled Process): Microstructure is achieved by cooling rate, sensitive to heat. Heat input is limited to ≤ 1.5 kJ/mm, interpass temperature kept ≤ 200°C. Low carbon equivalent (CEV ≤ 0.39) usually means no preheat is required.
  • S690QL — QT (Quenching + Tempering): Mechanical properties come from heat treatment. Preheat is mandatory (CEV-dependent), risk of hardness loss is less pronounced. Tolerates higher heat input.

We have separate WPSs for both materials. Indicating which one you use up front lets us prepare the correct procedure.

Q·17

Can you fabricate aluminium structures?

Yes. We perform TIG (141) welding on EN AW-5754 (AlMg3) and EN AW-6082 (AlSi1MgMn) alloys. Our aluminium qualifications:

  • Welder certificate: EN ISO 9606-2 — FM21 and FM22 material groups, PA · PB · PF positions
  • Welding procedure: EN ISO 15614-2-based WPQR — approved by destructive testing (tensile, bend, hardness, macro)
  • Acceptance criterion: EN ISO 10042 B class (for aluminium welds)

To prevent carbon-steel contamination in aluminium fabrication, separate tool sets and cleaning procedures are applied. We can share a sample WPS during the quote phase.

G.04

Logistics & Delivery

Q·15

What does the shipment include?

For standard delivery we quote according to Incoterms options including wooden crate or palletised packaging, corrosion protection (VCI), labelling, customs documentation and insurance: EXW FCA FOB CIF DAP.

Q·16

Do you also provide on-site assembly?

Yes — for structural steel and process equipment projects, on-site assembly + commissioning is offered as an option. Our installation team holds working-at-height, welding and crane certifications. For overseas site projects we provide a complete service including visas and equipment transport.

Q·17

Do you have export references?

Yes — we regularly export to Germany, Netherlands, Italy, Poland, Romania, Morocco and the UAE. We prepare all foreign trade documents like EUR.1, ATR, certificate of origin, CE DoP completely with our in-house foreign trade specialist.

G.05

After Sales

Q·18

What is your warranty period?

24 months warranty against workmanship and material defects. For wear parts (e.g. excavator bucket teeth), warranty coverage is contracted separately based on usage conditions. For PED and structural steel products warranty period may vary based on the CE application scope.

Q·19

Can I request a revision or repair?

Yes. We carry out revision, repair and life-extension work on parts we delivered or those from other manufacturers. After a status report, reverse engineering and the necessary NDT scans, we issue a refurbishment plan.

Q·20

I lost my documentation — can I get it again?

We archive all project documentation digitally for 10 years. When you create a request with the order number or project code, we resend WPS, WPQR, NDT reports, material certificates and dimensional control records as a PDF package within 48 hours.
