What do welders do?

February 25, 2021

Welders are professionals well-versed with the different welding processes. A welder uses numerous welding techniques to fabricate metal joints and components found in various industries and industrial products.

Welders are also responsible for ensuring that welding practices adhere to the prescribed quality and safety standards. They prepare materials and equipment for welding, inspecting, and analyzing the welded products to identify welding defects and their sources.

What Is Welding? What Is the Role of a Welder?

Welding is the process of joining metals by applying heat, pressure, or a combination of both.

When two metal parts are to be connected, heat and pressure help melt the two metals. Once the molten metal solidifies, the two parts connect together with a permanent bond.

Welding has considerable advantages over other joining processes.
You can create leak-proof joints, avoid vibrations due to loose fasteners, and even perform underwater welding. Since welding is a low-cost process and provides high joint strength, it remains one of the most preferred choices for joining metals.

Can you think of a sector where you don’t require the joining of metals? Metal joints find their use in bridges, structures, housing, automobiles, trains, power plants, oil refineries, and many such areas. Wherever there’s metal to be joined, there’s welding to be had!

What Are the Different Types of Welding?

Depending upon the metals you want to join, the strength of joints desired, and ease of operation, you can use one of the several weldings.

If you are looking to become a welder, you can gain expertise in any of the following techniques. The most commonly used methods of welding are:

Arc Welding

Arc welding uses an electric arc from an external power supply source to generate heat to melt and join metals. The power supply connects to the electrode that carries current or melts directly into the weld pool due to the applied heat.

This welding method is simple, inexpensive, fast, and reliable. You can find the applications of arc welding in the automotive, shipbuilding, and construction industries.

Flux-Coated Arc Welding (FCAW)

FCAW is a variation of arc welding. The electrode used for FCAW contains a flux that protects the weld pool from contamination. FCAW has a high metal deposition rate, making it ideal for high-speed applications like mass production lines.

Mild steel, low-alloy steel, and stainless steel are common materials that you can join using FCAW.

Shielded-Metal Arc Welding(SMAW)

SMAW is very similar to flux-coated arc welding. The only difference between SMAW and FCAW is that SMAW electrodes are solid and have an external covering of flux, while FCAW electrodes have a tubular shape with an inner flux core.

Gas Metal Arc Welding(GMAW)

Gas-metal Arc Welding(GMAW) or metal inert gas welding(MIG) uses a consumable wire-type electrode. A shielding inert gas flows through the welding gun and helps protect the weld pool from atmospheric contamination.

Originally developed for aluminum and other non-ferrous metals, GMAW is now used for welding steel and its alloys.

Gas Tungsten Arc Welding(GTAW)

GTAW or tungsten inert gas (TIG) welding is highly popular as it uses a non-consumable electrode. A tungsten electrode and a filler metal help create a joint between the two metals.

Inert gases such as argon or helium protect the area being welded from contamination, and most, although not all, welding applications will require filler metal.

Job Responsibilities of A Welder

Let’s take a look at the job responsibilities and the job description of a welder. Welders work in the manufacturing and construction industry and similar areas depending upon their skills and experience level.

A welder’s job description may involve one of the following responsibilities:

  • Fabrication of metal joints and products
  • Studying and analyzing drawings, blueprints, and sketches about metal joints.
  • Calculating the dimension of weld required for securing the metal parts to be connected
  • Ensuring that the workpiece adheres to prescribed quality and safety standards
  • Performing on-site inspections to check for defects and deviations
  • Recommending welding methods for joining a particular set of metals
  • Executing post-welding operations such as filling of holes, deburring, and hammering out the bulges and bends
  • Maintenance of the welding equipment and machinery

What are the Requirements for Becoming A Welder?

Given the scope, there is always a high demand for skilled people in the welding industry. If you want to take up a welding job or become a certified welding inspector, these are some of the requirements you must fulfill:


If you wish to become a welder, you will need a GED or high school diploma. Once you’ve obtained your GED, you can apply for a welding certificate program.

A typical welding certification program can take six to eighteen months. During your certification program, you will learn the various welding methods and techniques. To further enhance your employability, you can pursue an apprenticeship program for additional and on-the-job-training.

An Associate Degree in Welding Engineering Technology can pave the path for a fulfilling career. Students will learn the theory and undergo welding training for joining materials using the various welding processes during this two-year welding program.

Your college might also engage you with construction projects or manufacturing jobs during your apprenticeship to enhance your skills as a welder.


Along with the prerequisite education, training is an important part of becoming a welder. During their training and certification programs, welders work on live projects full time at the actual job location and handle welding equipment to complete their welding duties.

While working, the job instructor or shop floor manager will also teach welders about the various safety protocols important for handling power tools and equipment.

To fulfill your job duties as a welder, you can also take up one of the certification programs. Some of the most popular types of welding certificates are as follows:

  • Certified Welder (CW)
  • Certified Welding Inspector (CWI)
  • Senior Certified Welding Inspector (SCWI)
  • Certified Welding Educator (CWE)
  • Certified Welding Sales Representative (CWSR)
  • Certified Associate Welding Inspector (CAWI)
  • Certified Radiographic Interpreter (CRI)
  • Certified Robotic Arc Welding (CRAW)
  • Certified Welding Supervisor (CWS)
  • Certified Welding Engineer (CWE)


As a welder, you must also possess these traits for welding mechanical structures, construction products, and surfaces and performing a variety of welding jobs:

  • Physical fitness
