If this is an automotive application (i.e highly automated), I would look at low current Plasma Arc Welding. You get all the same advantages of GTAW (TIG or Heliarc as some say), but you get better arc starting. In some GTAW applications at low current you can blow away base metal when the arc...
One of the best specifications for meeting the intent of the FDA 21-CFR is the ASME BPE Standard. However, it is geared primarily at Tanks, Pressure Vessels and Pressure pipe or tube. AWS also has D18.1, but it only applies for pipe and tube.
Don't let the BPE (Bio-Process Equipment)name...
Henery,
I wouldn't take the CWI Seminar if your main work is in D1.1. Most of what is covered in basic math, basic weld knowledge and inspection criteria.
AWS offers many classes in many parts of country on just the D1.1 code. There will be a few next week (April 7th) in Detroit, MI at the...
Two big things to think about when welding on modern automobiles.
1) While a good practice when welding on anything anywhere, keep the work lead (also called the ground clamp) as close to the actual welding as possible. I have seen a few damaged bearings and transmissions from folks not...
With narrow gap SAW the angle between one weld face and another on the deposited weld is critical. This is likely contributing to the slag entrappment issue you have, assuming root and cover passes are not seeing this problem.
If adjusting parameters won't solve the problem you may need to...
The long (and complete) answer is look in the scope (U-1) of the code book (3 pages i length).
The short answer (rule of thumb) is that if it exceeds both of the following, and is not covered by another ASME code, it is most likely within the scope of section VII:
1. Greater than 15 PSI...
