What is the difference between a welder and a metal fabricator?

metal fabricators

Although they share many common responsibilities, welders and metal fabricators are two separate types of skilled workers in the metalworking sector. For organisations and people looking for specialised knowledge, knowing the difference between a welder and a metal fabricator is crucial.


Welders are professionals who use different welding procedures to fuse or connect metals. Welders use techniques including MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and stick welding to join together metals like steel, aluminium, and stainless steel. Their main concern is making connections between metal parts that will last. The following are the key responsibilities of a Welder:

Welding Techniques

Welders are professionals who know how to apply various welding processes to join metals together. Stick welding is widely utilised due to its adaptability and low cost. In contrast, MIG welding is preferred due to its efficiency and speed, and TIG welding due to its accuracy and clean finishes.

Blueprint Interpretation

Welders often follow technical drawings or blueprints that outline the project’s precise welding specifications. To guarantee proper implementation, they will need to understand these papers.

Metal Preparation

It is the responsibility of the welder to establish the desired joint configurations by cleaning, beveling, or cutting the metal surfaces prior to welding. Strong, long-lasting welds can only be achieved through thorough prepping.

Weld Quality Control

The onus is on the welder to check their work for proper completion. Weld penetration, strength, and aesthetic quality are all things to be examined.

Metal Fabricator

Fabricators of metal, on the other hand, are responsible for more than just welding. They take part in every step, from conceptualization to final assembly, of fabricating metal frames and parts. Fabricators use a wide range of tools and machinery to mould metal into the required shapes and then put them together. The following are the key responsibilities of a Metal Fabricator:

Design and Planning

Metal fabricators take part in both the conceptual and strategic phases of building. To determine the needs and develop the fabrication strategy, they collaborate with engineers and project managers.

Metal Cutting and Shaping 

Metal components are cut and shaped by fabricators using a wide range of instruments, including shears, saws, and laser-cutting machines. Sheet metal may be cut, bent, rolled, or formed to conform to the specifications of the design.


Metal fabricators put together the parts to make the whole. Welding, bolting, or other forms of fastening may be used to unite the parts.

Quality Control

Metal fabricators, like welders, are accountable for the quality of their finished products. Throughout the fabrication process, they check the components for correctness, alignment, and quality.

Reading Blueprints

The ability to read and understand technical drawings and blueprints is essential for success in the metal fabrication industry. For this, you’ll need to study the blueprints and get familiar with their tolerances and requirements.


Metal fabricators have a broader function than welders do since they also design, cut, shape, and assemble metal components in addition to connecting them. Welders and metal fabricators are equally important in the metalworking business.
