When inspecting boiler tube welds, outage time and resources are key inspection challenges. The industry requires a rapid volumetric non-destructive testing (
How do you test a weld?
When it comes to Non Destructive Testing or "NDT" there are many ways to test the quality of the weld.
The three most common methods are:
Visual weld inspection.
Liquid dye penetrant testing.
Radiographic testing or x-ray. Is a welder qualification test easier than a welding certification?
The tests vary in positions, welding processes, and the type of welding inspection to be used.
Some job sites may only do a visual inspection, others might conduct a bend test, and for most pipe welding jobs it is likely your weld will be x-rayed.
Do not get the impression that a welder qualification test is easier than a welding certification.
Pipe Welding Certification Positions
When it comes to welding pipe there are four main positions and again they are typically groove welds.
There is also a coding system to identify the positions and joint types.They are as follows: 1. 1 is for a pipe in the horizontal position that is rolled. 2. 2 is for a pipe in the fixed vertical position. 3. 5 is for a pipe in the fixed horizonta.
Plate Welding Certification Positions
For welding plate the positions typically come in two different joint types.
Fillet welds and groove welds.
Most plate welding certifications are performed in groove welds.
This is because in most welding codes, grove welds will also qualify you for fillet welds, but fillet welds do not cover groove welds.
Fillet welds and groove welds also vary in.
Welder Certification Backing Bar vs. Open Root Weld
As with all welding certifications many offer two types of root openings.
The first is typical of plate or structural welding certifications and that a backing bar is used.
The second is an open root type of weldthat is commonly used on pipe welding certifications.
These two types of roots both have advantages depending on the type of work being do.
Welding Certification Positions
The largest organization in America that certifies welders is the American Welding Society.
The welding certification procedures they have approved have been tested many time to ensure that if followed the welder taking the welding certification follows the rules and has the skills will pass the test.
Welding certifications come in many positions, .
What is a combo welding test?
This is considered a combo type of test because it certifies you in two welding processes.

What welding test do power plant Welders use?
One of the typically welding test for pipe welders in a power plant construction is a pipe in the 6G position using a TIG root and hot pass with the remainder of the pipe Stick welded out with either a E7018 or a E8018″.
