What is the meaning of Coded Welder

In the UK, welder approval codes are to BS EN (now ISO) standards. The USA uses the ASME IX standard.

The coding system is a set of required tests that proves a welders competence.

Some codes are more general and varied, but more often, they are project-specific.

The more specific methods need individual parameters allocated via a weld test inspector.

It requires the engineer to undertake a test to that specification.

The engineer will then offer a welding sample that mirrors the position as close as possible.

An approved CSWIP test examiner will then review to see if it’s at the required standard.

The examiner usually tests visually and destructively.

If successful, then they become Coded to that specification.

Being Coded in a particular specification does not mean you are in another.

Each specification requires welder training, welding tests and examination, becoming a multi-coded welder.

Coded welders are generally re-tested every two years.

What are the different types of welding?
TIG – Also Known as Gas Tungsten Arc Welding (GTAW). We use TIG when weld integrity is critical and requires high-quality welds. TIG leaves no splatter and minimises potential defects during the welding process.

MIG – also known as Gas Metal Arc Welding (GMAW). MIG is the most common industrial welding process. It produces high-quality welds much quicker. It also covers a wide variety of metals and alloys.

MMA – also known as Stick Welding or Shielded Metal Arc Welding (SMAW). MMA is a low-cost technique and is very versatile. Once mastered, the engineer can use it on a wide variety of materials in almost any environment and position.

Fusion Welding – This method is for welding polythene pipes such as MDPE. They are using heat and copper wire to fuse/melt the ends together. Gas and Water pipework usually require Fusion Welding. It can also be used for acidic environments where other materials would fail or degrade over time.

Coded Welders at Varlowe Industrial Services
Here at Varlowe Industrial Services, we have a team of multi-coded welders.

We cover an extensive range of specifications, materials, diameters and thicknesses.

All our operatives’ welder approvals are supported by a qualified welding procedure (WPQR).

Based out of our Wolverhampton head office, we offer a nationwide mobile welding service.

Our coded welders can work from our fully equipped mobile welding vehicles. This allows us to offer support at your site, even in remote locations.

We are your complete Welding Service.
