Comparision of major NDT methods for Nondestructive testing of Welds

Method	Equipment Required	Enables Detection of	Advantages	Limitations	Remarks
Visual	Magnifying glass Weld sizing gauge Pocket rule Straight edge Workmanship standards	Surface flaws - cracks, porosity, unfilled craters, slag inclusions Warpage, underwelding, overwelding, poorly formed beads, misalignments, improper fitup	Low cost. Can be applied while work is in process, permitting correction of faults. Gives indication of incorrect procedures.	Applicable to surface defects only. Provides no permanent record.	Should always be the primary method of inspection, no matter what other techniques are required. Is the only "productive" type of inspection. Is the necessary function of everyone who in any way contributes to the making of the weld.
Radiographic	Commercial X-ray or gamma units made especially for inspecting welds, castings and forgings. Film and processing facilities. Fluoroscopic viewing equipment.	Interior macroscopic flaws - cracks, porosity, blow holes, nonmetallic inclusions, incomplete root penetration, undercutting, icicles, and burn through.	When the indications are recorded on film, gives a permanent record. When viewed on a fluoroscopic screen, a low-cost method of internal inspection	Requires skill in choosing angles of exposure, operating equipment, and interpreting indications. Requires safety precautions. Not generally suitable for fillet weld inspection.	X-ray inspection is required by many codes and specifications. Useful in qualification of welders and welding processes. Because of cost, its use should be limited to those areas where other methods will not provide the assurance required.
Magnetic Particle	Special commercial equipment. Magnetic powders - dry or wet form; may be fluorescent for viewing under ultraviolet light.	Excellent for detecting surface discontinuities - especially surface cracks.	Simpler to use than radiographic inspection. Permits controlled sensitivity. Relatively low-cost method.	Applicable to ferromagnetic materials only. Requires skill in interpretation of indications and recognition of irrelevant patterns. Difficult to use on rough surfaces.	Elongated defects parallel to the magnetic field may not give pattern; for this reason the field should be applied from two directions at or near right angles to each other.
Liquid Penetrant	Commercial kits containing fluorescent or dye penetrants and developers. Application equipment for the developer. A source of ultraviolet light - if fluorescent method is used.	Surface cracks not readily visible to the unaided eye. Excellent for locating leaks in weldments.	Applicable to magnetic and nonmagnetic materials. Easy to use. Low cost.	Only surface defects are detectable. Cannot be used effectively on hot assemblies.	In thin-walled vessels will reveal leaks not ordinarily located by usual air tests. irrelevant surface conditions (smoke, slag) may give misleading indications.
Ultrasonic	Special commercial equipment, either of the pulse-echo or transmission type. Standard reference patterns for interpretation of RF or video patterns.	Surface and subsurface flaws including those too small to be detected by other methods. Especially for detecting subsurface lamination-like defects.	Very sensitive. Permits probing of joints inaccessible to radiography.	Requires high degree of skill in interpreting pulse-echo patterns. Permanent record is not readily obtained.	Pulse-echo equipment is highly developed for weld inspection purposes. The transmission-type equipment simplifies pattern interpretation where it is applicable.

Forging temperatures of commonly used Metals

Forging temperature is a temperature at which a metal becomes soft like clay or its shape can be changed by applying a relatively small force without creating cracks in metal. Chart for forging Temperature (Please note the temperature given here is for reference only. Actual temperatures may vary depending on specific composition of metals):

Material	Celsius	Fahrenheit
Carbon Steel	1230	2246
Stainless steel (Magnetic)	1095	2003
Stainless steel (Nonmagnetic)	1150	2102
Nickel	1095	2003
Titanium	955	1751
Copper	900	1652
Brass	815	1499

 About AWS-CWI

The Certified Welding Inspector (CWI) certification is more than a rewarding career. It involves great responsibility and remarkable skill demonstration. The CWI is widely recognized, both nationally and internationally, and successful companies have come to rely on this AWS certification when ensuring the highest level of quality workmanship. In a survey it has been found that welding work under supervision make a valuable contribution to the four most important metrics in welding operations: quality, cost, productivity and safety.

The benefits of AWS CWI Certification:

• Internationally recognized and accepted.
• Obtain certification as a welding inspector that demonstrates a level of proficiency to a defined internationally accepted standard.
• Improve welding inspection skills, expand knowledge base, learn use of diverse fabrication, inspection and testing codes, standards and specifications.
• Qualification tests and inspection reports signed and approved by a CWI add credibility that testing and inspection has been done to industry recognized standards.
• Leads to a career that is highly remunerative, engaging and promising on all levels.

Cracks on steel tubes observed using magnetic particle testing

'Trinity NDT' carried out raw material NDT on steel Dia 16mm tubes. The cracks observed on ST52 tube material are reproduced here. Some of them are through thickness cracks. The team segregated the defective materials using magnetic particle testing. Visit: www.trinityndt.com to know more about the NDT inspection services and training and certification courses.

Watch & Download magnetic particle testing video by Trinity NDT- A Training Video

Magnetic particle testing is one of the most widely used NDT method for detecting surface and subsurface flaw at all the stages of manufacturing and particularly in the raw material stage to detect serious discontinuities and to weed out defective materials.

Watch an excellent video by Trinity NDT on Magnetic Particle testing carried on a rolled bar at the material testing facility in Bangalore-India using electromagnetic wet non-fluorescent yoke technique. As the surface is in as rolled condition, for better contrast and hence the detectability the team used "Magnaflux" white contrast paint.
