Introduction
For a small or growing manufacturing company, quality and inspection needs can get complicated fast.You might need trained staff, inspection steps, technical checks, certification processes, audit help, and support for different non-destructive testing methods.But that doesn’t always mean you need a full-time NDT Level 3 specialist working for you all the time.
In many situations, the real question isn’t:
“Do we need Level 3 expertise?”
It’s:
“Do we need a full-time Level 3 professional?”
For smaller manufacturers, the answer depends on things like how much you produce, which NDT methods you use, what your customers ask for, how strict the certification rules are, and how often Level 3 tasks come up.
This guide helps you decide between cost and capability so you can pick the best option for your real needs.
What Does an NDT Level 3 Actually Do?
An NDT Level 3 is not just someone who does inspections.
Level 3 personnel usually have more technical responsibility in an NDT program.
Depending on the standard, certification system, and organization, their job might involve things like overseeing technical work, creating or approving procedures, understanding and applying requirements, training or testing others, and helping with difficult inspection situations.
For a manufacturer, this expertise is especially useful when dealing with:
– Using multiple NDT methods
– Handling complex inspection needs
– Meeting customer-specific requirements
– Ensuring welding quality
– Writing procedures
– Meeting qualification standards
– Conducting audits and getting certified
– Dealing with non-conformities
– Choosing the right inspection method
– Interpreting technical requirements
The key thing is that Level 3 skills can be very valuable even if the company doesn’t need them every single day.
That’s when the question of whether the cost is worth the benefit comes into play.
Why Smaller Manufacturers Face a Level 3 Dilemma
Large companies might have enough inspections to justify having their own NDT experts.
A smaller company could be in a completely different situation.
For example, think of a company that:
– Makes welded parts
– Uses methods like ultrasonic testing, magnetic particle testing, or penetrant testing from time to time
– Has a small team for inspections
– Produces only a limited number of items
– Only needs a Level 3 expert for certain special tasks
– Doesn’t need Level 3 work on a regular basis
In such a case, hiring a full-time expert might not be the best fit.
They would have the expert always available, but might only use their skills occasionally.
On the other hand, if they rely only on Level 2 workers without proper supervision, they might miss important technical skills.
So, the choice comes down to finding the right balance between:
– Cost
– Availability
– Technical skills
– Compliance needs
Full-Time NDT Level 3 vs Outsourced Level 3
There are two common approaches manufacturers may consider.
Option 1: Hire a Full-Time Level 3
The company has an NDT Level 3 specialist working as part of its own team.
This setup offers several benefits:
– The specialist is always available internally
– They are directly involved in conducting inspections
– Technical decisions can be made more quickly
– Knowledge about NDT stays within the company
– The company has more control over NDT processes
But the cost isn’t just the salary.
There may also be expenses related to hiring, benefits, training, keeping certifications up to date, covering for time off, and other things related to employment.
Option 2: Use External or Outsourced Level 3 Expertise
The company brings in skilled outside experts when needed.
This method can be helpful when Level 3 tasks happen only sometimes, not all the time.
Some possible benefits are:
– Getting expert help when it’s needed
– Having fewer permanent staff commitments
– Being able to adjust based on project needs
– Gaining experience from different situations
– Not needing to keep a full-time specialist on staff
– However, outsourcing isn’t always the best option.
Before choosing a solution, it’s important to think about the manufacturer’s standards, customer needs, certification rules, and real technical duties.
Understanding the Real Cost of a Full-Time Level 3
A common error is looking only at the salary of a Level 3 compared to the cost of an outside service.
The real cost to the business can include more than just that.
Think about these areas:
| Cost Factor | Full-Time Level 3 | External Level 3 |
|---|---|---|
| Fixed salary | Yes | No |
| Employee benefits | Usually | No |
| Recruitment | Yes | Usually no |
| Certification maintenance | Organization/individual dependent | Organization/individual dependent |
| Continuous availability | High | Based on agreement |
| Technical expertise | Internal | External |
| Workload flexibility | Lower | Higher |
| Cost during low workload | Still incurred | Potentially lower |
| Internal knowledge retention | High | Lower |
| Project-based scalability | Limited | Higher |
This is why manufacturers should evaluate total cost of ownership, not just the monthly salary.
When Outsourced NDT Level 3 Makes Sense
Outsourcing Level 3 NDT services could be a good option when a company needs specialized skills but not all the time.
For example, a manufacturer might need Level 3 help with:
Developing or reviewing an NDT procedure.
Reviewing complex inspection tasks that go beyond what a regular Level 2 team can handle.
Meeting specific NDT or quality standards that require extra technical understanding.
Getting ready for audits from customers, certification bodies, or quality authorities.
Trying out a new NDT technique without having to hire someone permanently right away.
Meeting certification requirements at certain stages of the process.
The main thing to think about is how often the Level 3 work is needed.
If the need happens only occasionally, keeping a full-time Level 3 person might not be the best choice for the company.
When a Full-Time Level 3 May Be Justified
Outsourcing is not always the best choice.
Having a full-time NDT Level 3 staff member might be better when there is a lot of ongoing technical work that needs attention.
You should think about having an internal Level 3 if:
– NDT is a big part of the daily work
– Many different NDT methods are used all the time
– There is a steady and high volume of inspections
– Technical choices are needed every day
– The company has a large team that does inspections
– The procedures used often need to be changed or updated
– Customers have very complex requirements
– The business runs operations in several different locations
– There is a strong need for quick and direct technical decisions from inside the company
In these situations, having an experienced professional on staff may be more valuable than the extra cost of hiring outside.
NDT Level 2 vs Level 3: Why the Difference Matters
A Level 2 professional can carry out and understand NDT tests as allowed by their qualifications and the right procedures.
Level 3 roles include more advanced technical guidance, such as creating procedures, choosing methods, evaluating techniques, and other duties set by the relevant certification standards.
So, manufacturers shouldn’t just see Level 3 as someone with more experience than a Level 2 inspector.
It’s better to view Level 3 as a more advanced technical role within the NDT process.
Key Factors to Consider Before Making a Decision
1.How often do we need Level 3 expertise?
If the need is every day, having internal staff might be a good idea.
If it’s only sometimes, using outside experts might be more cost-effective.
2.How many NDT methods are we using?
Using several different methods can make things more complicated from a technical point of view.
3.What standards do we need to follow?
The standards that apply to your work and any certification needs can greatly affect the kind of expertise you need.
4.What do our customers want?
Customer demands can sometimes add requirements that go beyond what the company usually does in its inspection process.
5.How big is our inspection team?
Having a bigger inspection team might make a strong case for having a dedicated technical leader.
6.How complicated are our products?
Simple and repetitive products may need less technical help than complex welded parts or important components.
7.How often do we need to create or change procedures?
If you often have to develop or update procedures, having Level 3 expertise on hand becomes more valuable.
8.What happens during audits?
If audits often require technical documents and NDT knowledge, the company should take this into account when making decisions.
A Simple Cost vs Capability Decision Framework
Which option gives us the needed ability at the right cost?
Use this simple guide:
Choose Full-Time Level 3 When:
There is a lot of work + frequent technical choices + several NDT methods + constant needs
↓
Having an internal Level 3 expert might be a good idea
Consider External Level 3 When:
There is not a lot or just some work + occasional technical needs + limited NDT complexity
↓
Hiring an outside Level 3 expert might be better
Consider a Hybrid Approach When:
There is regular Level 2 inspection + some Level 3 needs from time to time
↓
Use an internal inspection team + bring in external Level 3 help when needed
For many smaller manufacturers, the hybrid model is worth looking into because it separates daily inspection tasks from specialized technical demands.
The Real Question Isn't "Do We Need Level 3?"
A full-time NDT Level 3 technician can give strong internal support, but this comes with a commitment to keep that person on staff all the time.
Hiring external NDT Level 3 experts can be better when you only need their skills occasionally.
The best option depends on several factors like the manufacturer’s workload, the NDT techniques used, the standards that apply, customer needs, how complicated the production is, and future growth plans.
Some manufacturers find that having a full-time Level 3 technician makes sense.
Others might prefer to use outside or outsourced Level 3 experts when needed.
For many growing companies, a mix of internal and external NDT Level 3 support can be a good balance between having reliable in-house inspection and access to specialized technical knowledge.
Frequently Asked Questions
Do small manufacturers need an NDT Level 3?
Not necessarily as a full-time employee. The requirement depends on applicable standards, certification schemes, customer specifications, NDT methods and the manufacturer’s technical responsibilities.
What is outsourced NDT Level 3?
It involves engaging qualified external Level 3 expertise for specific technical activities instead of maintaining a full-time Level 3 position internally.
Is outsourced NDT Level 3 cheaper than hiring a full-time Level 3?
It can be, particularly when Level 3 expertise is required only periodically. However, the decision should consider the actual scope and frequency of work rather than price alone.
Can Level 2 inspectors work without Level 3?
This depends on the applicable certification scheme, standards, procedures and organizational requirements. Level 2 and Level 3 have different scopes of responsibility.
When should a manufacturer hire a full-time Level 3?
A full-time position may make sense when NDT activities are frequent, technically complex and require continuous internal oversight.
What should a small manufacturer consider before outsourcing Level 3?
Consider applicable standards, customer requirements, NDT methods, workload, technical responsibilities, audit requirements and the frequency with which Level 3 expertise is needed.
Conclusion
Small manufacturers don’t have to pick between having Level 3 expertise and saving money.
A better idea is to think about how often that expertise is really needed.
If Level 3 tasks are something that happens all the time, then having an internal expert could be the best choice because they can be there whenever needed.
But if those tasks come up only sometimes, using an outside Level 3 NDT specialist might be more flexible.
In the end, the choice should be based on what’s needed, how things are regulated, how busy things are, and the overall cost — not just how many people you have.
The aim isn’t to have the largest NDT team.
The aim is to have the right NDT skills for the actual work you do.
