Production Ready

Even when a welding company has many welders, this situation can still happen.

The real issue isn’t really about hiring people.
The main problem is that there’s no good system in place for training and certifying welders.

When experienced welders leave and new workers come in, or when production needs suddenly go up, companies might end up giving welding jobs to people who aren’t properly trained or qualified.

It’s better to set up a clear internal process where workers move through steps like training, practical testing, certification, production evaluation, and then renewal.

Companies that use ISO 9606 or European welding standards can really benefit from having such a system in place.

Why Manufacturers Need an In-House Welder Training Pipeline

Having an experienced welder doesn’t automatically solve problems with qualifications.

It’s possible that someone has many years of experience but still lacks the proper qualifications for a specific welding method, material, position, thickness, or purpose.

This becomes even more important if the company has set up systems for controlling welding quality.

For example, EN ISO 3834 highlights the need for qualified people, controlled processes, testing, traceability, and proper documentation of quality control.

The solution to this issue is to see qualifications not just as an HR matter, but as part of the manufacturing and quality control process.

Training vs ISO 9606 Qualification: What Is the Difference?

It’s important to understand the difference.

Training helps someone become skilled.
Qualification shows that someone can do the job well according to specific standards.

ISO 9606-1:2012 sets the rules for testing welders who do fusion welding on steel.
The standard focuses on showing that a welder can make good welds using clear guidelines.

However, this standard does not include a full training program for a company.

This means that the company must create its own training plan and help people get ready for the qualification test.

The International Institute of Welding also makes a similar distinction between its training guidelines and the ISO 9606 qualification tests.

The 5-Stage Welder Training Pipeline

1.Finding the Skill Gap in Production

Start by understanding what your plant makes.

Map the following:

– Welding methods
– Types of base metals
– Kinds of joints
– Plates and pipes
– Welding techniques
– Welding positions
– Thicknesses and diameters
– Welding procedures that are used
– Customers and projects

Don’t train all your welders on every skill.
Instead, train them based on the skills they lack in your production process.

2.Checking the Current Skills of Welders

Before starting training, check each worker’s skills.

An assessment sheet can include:

Skill	Current Level	Required Level	Action
Process 111	Basic	Qualified	Practical training
Process 135	Intermediate	Qualified	Qualification preparation
Pipe welding	Basic	Advanced	Extended practice
Position PF	Basic	Required	Position training

This method helps the company save time by not needing to train already qualified workers and instead focus on fixing actual problems.

3.Train Based on Real Production Conditions

During training, employees should be given the same real-life conditions they will face on the production floor.

This means using the correct welding procedures (WPS), materials, joint designs, welding positions, and settings.

The goal of training isn’t just to make a good-looking test piece.
The employee must be able to consistently perform welding tasks using the right methods in real production.

This is why having a structured internal system is much more helpful than just learning through trial and error on the job.

4.Prepare for the Certification Process

Once the required skill level is reached, the right certification process is chosen.

ISO 9606-1 outlines the process for certifying fusion welding of steel, including the test conditions and what qualifies as a valid test.

So, the manufacturer should look at their production needs before deciding what test to perform.

A good approach is:

Production needs → Welding Procedure Specification (WPS) → Training → Practical test → Qualification test → Certificate → Production task

5.Monitoring and Maintaining the Qualified Workforce

Qualification is not the end of the process.

It’s important to keep records of:

Qualified welder certificates
Welding processes used
Qualification ranges
Production activities
Renewal every six months when necessary
Additional training
Requirements for re-qualification or renewal
WPSs assigned to each welder

These records create a living record of each welder’s skills and qualifications, which the production and quality control teams can use before assigning welding tasks.

For more information on how long certificates are valid and how they are renewed, see our detailed article on ISO 9606-1 Welder Qualification: Validity, Continuity & Renewal Explained (2026).

How to Connect Training With WPS and Production

One of the biggest errors is when welder training is done without following the company’s welding procedures.

Connect these three parts: welder, WPS, and production job.

For instance, if a production line regularly uses a certain type of process, material, thickness, or position, that should shape the training and what the welder is qualified for.

Instead of just asking, “Is this welder qualified?” the welder’s certificate should be checked against the specific needs of the production job.

This helps the company better control its WPS and WPQR processes overall.

How EN ISO 3834 and EN 1090 Fit Into the System

When welding is part of a bigger system that follows quality standards, having a well-organized way to train welders is very helpful.

EN ISO 3834 is about controlling the quality of welding.
It covers things like making sure people are properly trained, using correct welding methods, checking the work, using right equipment, and keeping good records.

For companies that make structural steel and follow EN 1090, having trained workers and controlled welding processes becomes part of their overall system for managing production.

This leads to a system where everything works together instead of being separate steps:

Training → Welder Qualification → Welding Procedure Specifications/Welding Procedure Qualification Records → Production → Inspection → Traceability.

Frequently Asked Questions

What is an in-house welder training pipeline?

It is a systematic process by which a company can determine the needs for welding skills, train employees, evaluate their competence, prepare them for qualification and keep the qualifications during production.

Does ISO 9606 itself provide a welder training programme?

No. ISO 9606 sets the requirements for qualification tests. Training programmes should be done separately. IIW has its guideline for theoretical, practical training and examination of International Welders.

Can an experienced welder get into the process of qualification?

Yes, he or she can be a candidate for qualification test, but before that, the manufacturer should make sure that his or her skills and the intended qualification range correspond to the production needs.

What information must be recorded about every qualified welder?

At least the following one: the respective certificate, welding processes, qualification range, production work, continuity and requalification/renewal requirements.

Will ISO 9606-1 be actual in 2026?

Yes. According to ISO, ISO 9606-1:2012 is the current edition, and ISO/DIS 9606.2 is being developed to replace some parts of the series.

Conclusion

Hiring welders quickly isn’t the right solution.

Manufacturers need a dependable way to build a skilled welding team that learns the right skills, connects their training to real production needs, and gets the right qualifications.

This method helps manufacturers reduce last-minute hiring, understand the current skill level of their workers, and ensure welding quality meets standards.

The solution is straightforward:

Teach the right people the right skills.
Give them the qualifications needed for their jobs.Keep track of their abilities.Make sure production matches their skill level.
