Welder Practice Interprovincial 310T Red Seal Exam

Disclaimer: This is NOT an Interprovincial Standards (Red Seal) Examination. This is a practice examination that has been developed using similar weighting, question distribution, question taxonomies and question styles to that of a red seal examination. Success on this examination will NOT result in certification or qualification. This examination is intended to be used for self-assessment in preparation for attempting a red seal examination. More information about the standard that the red seal examination is based on may be found within the National Occupational Analysis for the occupation at www.red-seal.ca.

 

Welders level A & B permanently join pieces of metal by applying heat, using filler metal or fusion process. They join parts being manufactured, build structures and repair damaged or worn parts. They also fabricate parts, tools, machines and equipment used in the construction and manufacturing industries.

To prepare for the Red Seal exam please use the NOA information below.
