Proper Testing
The proper way to analyze a flux coated rod:
– make a weld puddle / spot with the rod;
– then place the analyzer directly on the weld spot to test.

Welding Grade Chemistry
Welding grades often have slightly higher concentrations of the alloying material.
Grade Name Cr Mn Ni316 16 - 18 0 -2 10 - 14ER316 (Weld) 18 - 20 1 - 2.5 11 - 14321 17 - 19 0 - 2 8 - 10.5ER321 (Weld) 18.5 - 20.5 1 - 2.5 9 - 10.5

Spot Collimation
Narrows the X-ray beam to a smaller spot size
Useful for targeting a narrow weld;
Allows user to analyze the weld, the base material, or the heat affected zone.

The DELTA Weld Mask reduces the analysis area without collimation
Not as convenient as camera with collimator
The DELTA has an optional Weld Mask
