There are 22 technical AWS committees responsible for more than 100 standards covering a wide
range of areas related to welding.
It should be noted that there is a strong and active Canadian participation on the AWS committees.
This participation is dictated by the desire to keep welding standards in both countries at the same
advanced level and without any major differences, to effectively support the high volume of trade
between them.
