1.) Destructive Testing
2.) Non-destructive Testing
DESTRUCIVE TESTING
As the word implies, specimens tested by destructive testing, the specimens are destroyed during the test and are worthless after the test. Example of destructive testing are; bent test, tensile test etc
NON-DESTRUCTIVE TESTING
The quality of specimens are tested without destruction. Example of non-destructive testing are; radiographic testing, magnetic particle testing, penetrant testing, ultrasonic testing and eddy current testing
Each method of NDT (Non-destructive Testing) has its own advantages and disadvantages. Choosing the method to be used depends on the data of items to be tested.
Blogger UT-Man is an expert in UT and other NDT methods.

Welding Inspector's Course Schedule
I will be conducting Welding Inspector's Course on June 16-20, 2008 @ Sn. Vicente, Tarlac City.
If you are interested in attending this course, please feel free to contact me or post in this site.
This course is intended for graduate engineers, engineering students, graduate of any 4 year degree who wants to pursue their career in Welding Inspection and QA/QC.
The course content are; Duties and responsibilities of a welding inspector; welding processes; weld defects; types of steel; weldability; heat treatment; visual inspection; testing parent metals and welds; destructive tests; NDT techniques; welder and procedure approval; codes and standards; safe working practices
The course Fee is P5,000.00 inclusive of snacks, lunch and training material.

Causes of Lack of Fusion
1.) Joint preparation is too narrow
2.) Insuficient cleaning of weld joint
3.) Oily weld joints
4.) Poor welding technique
5.) Magnetic Arc Blow
6.) Wrong welding parameter settings

What is Welding Discontinuity and Welding Defects?
Discontinuity - an objective lack of material, an interruption in the physical consistence of a part.
Defect - an excessive conditions, outside the acceptance limits, which risks to compromise the stability or the functionality of the welded structure
