ANSWER According to AWS D1.1, how long does welder qualification last?
5/16: ANSWER Using just one electrode for SAW When employing a
prequalified method, what is the largest size single pass fillet weld that can be
applied in the horizontal welding position?
If required, once every three years or less— ANSWER How frequently must
inspectors under AWS D1.1 undergo ocular examinations?
Ten hours— ANSWER What is the minimum holding time per inch of
thickness when stress relieving a weldment at a temperature 150F below the
minimum required temperature?
ANSWER Steel backing for welds in statically loaded structures does not have
to be welded all the way through or removed unless the engineer specifies
otherwise.
The ANSWER is 1/8 inch. For a welding technique certification on pipe or
tube with a wall thickness of 0.028 inches, the maximum amount of weld
reinforcement allowed is:
One is for electrodes made of low alloy steel, and the other is for electrodes
made of plain carbon steel. What distinguishes the standards between AWS
A5.1 and A5.5?
ANSWER Tack welds integrated into SAW welds must also satisfy all of the
, aforementioned requirements.
A variation of 5% over the average amperage for every filler metal diameter
utilized— ANSWER For GMAW, which isn't thought to be a crucial factor for
the method certification
