How to get Welder Certificate?

Welder Certificate is a document that shows ability of a welder to make a quality weld in a particular welding process.

Welder Certificate

The Certificate also denotes on which type of welding material and which position the welder is able to perform.

A full penetration weld can be performed by welder who is qualified for full penetration & fillet. A welder qualified by vertical position (3G) can perform Flat and vertical in production and so on.

These qualification ranges are mentioned in the certificates after referring the applicable codes and standards.

Welders are qualified for different process individually.

Welding process:

  • Shielded Metal Arc Welding (SMAW)- Arc Welding
  • Tungsten Inert Gas Welding (TIG/GTAW)- Arc Welding
  • Metal Inert Gas Welding (MIG)- Arc
  • Metal Active Gas welding (MAG)- Arc
  • Flux Cores Arc Welding (FCAW)- Arc
  • Electric Resistance welding (ERW) and Lot more..

Welding Qualification standards are given in

  • AWS D 1.1 – Structural Welding Code- Steel.
  • AWS D 1.3 – Sheet metal welding code.
  • AWS D 1.6 – Stain steel Welding
  • ASME section IX – Boiler & pressure vessel/pipelines Arc Welding.
  • ISO 9606-1- International Standard for Arc Welding.

What are the procedures for welder qualification? Or What is the procedure for qualifying a welder?

  • Conclude the range of qualification such as, plate or pipe, thickness, metal grades, pipe diameter, full penetration or fillet.
  • Choose an appropriate WPS – Welding Procedure specification
  • Prepare a test coupon to the required dimension- refer code for dimension
  • Tack welds the test coupon in the required positon with appropriate root gap bevel preparation.
  • Make the welding as told in the WPS
  • Visually inspect the coupon
  • Make a bend test or Radiography( RT) on the test coupon.
  • After clearing the test- the welder is qualified.
