Liked that. Quick and so shareable.

Good one.

I do not agree that this is a true representation of what Technical Safety is but I am no specialist to comment.
All I could see Equipment Integrity & Reliability considered within Technical Safety is not appropriate.

Carbon, yes, is the difference.
Ease with CPF3M when welding is involved.

Any material which has been alloyed more than 8% according to most of the literatures should be considered as high alloy.
Lower alloying percentage is low alloy range.

Many different uses with all these different welding types, in short.
Say for accurate, penetrated welds, gas tungsten is the one preferable.
Stick welding is used anywhere any day.
Then the materials which are being welded, so all many factors to consider.
