7. Q:-What are the common welding defects?

Answer: -
  1. Lack of penetration.
  2. Lack of fusion.
  3. Undercut.
  4. Slag inclusion.
  5. Porosity.
  6. Crack.
  7. Faulty weld size & profile.
  8. Distortion.
  9. Lack of penetration.
This defect occurs at the root of the joint when the weld metal fails to reach it or weld metal fails
to fuse completely the root faces of the joint. As a result, a void remains at the root zone, which
may contain slag inclusions.
Cause: -
  1. Use of incorrect size of electrode in relation to the form of joint.
  2. Low welding current.
  3. Faulty fit-up and inaccurate joint preparation.
  4. Lack of fusion.
Lack of fusion is defined as a condition where boundaries of unfused metal exist between the
Weld metal & base metal or between the adjacent layers of weld –metals.
Cause: -
  1. Presence of scale, dirt, oxide, slag and other non-metallic substance which prevents
the weld metal to reach melting temperature.
  1. Improper deslagging between the weld pass.
Precaution: -
  1. Keep the weld joint free from scale, dirt, oxide, slag and other non- metallic substance.
  2. Use adequate welding current.
  3. Deslag each weld pass thoroughly.
  4. Place weld passes correctly next to each other.
  5. Undercut
This defect appears as a continuous or discontinuous groove at the toes of a weld pass and is
located on the base metal or in the fusion face of a multipass weld. It occurs prominently on the
edge of a fillet weld deposited in the horizontal position.
Cause: -
  1. Excessive welding current.
  2. Too high speed of arc travel.
  3. Wrong electrode angle.
Rectification: -
The defect is rectified by filling the undercut groove with a weld pass. If undercut is deep &
contains slag, it should be chipped away before rewelding.
  1. Slag Inclusion
Non–metallic particles of comparatively large size entrapped in the weld metal are termed
as slag inclusion.
Cause: -
  1. Improper cleaning of slag between the deposition of successive passes.
  2. Presence of heavy mill scale, loose rust, dirt, grit & other substances present on the
surface of base metal.
Precaution: -
  1. Clean the slag thoroughly between the weld pass.
  2. Keep the joint surface (especially gas cut surface) and bare filler wire perfectly clean.
  3. Avoid undercut & gaps between weld pass.
  4. Use proper welding consumables.
  5. Porosity
The presence of gas pores in a weld caused by entrapment of gas during solidification is
termed as porosity. The pores are in the form of small spherical cavities either clustered locally
or scattered throughout the weld deposit. Sometimes entrapped gas give rise to a single large
cavity called Blowholes.
Cause: -
  1. Chemically imperfect welding consumables, for example, deficient in deoxidiser.
  2. Faulty composition of base material or electrode, for example, high sulphur content.
  3. Presence of oil, grease, moisture and mill scale on the weld surface.
  4. Excessive moisture in the electrode coating or submerged-arc flux.
  5. Inadequate gas shielding or impure gas in a gas –shielded process.
  6. Low welding current or too long an arc.
  7. Quick-freezing of weld deposit.
  8. Crack
Fracture of the metal is called crack. Two types of cracks: - Cold crack & Hot crack.
Cold crack usually occur in HAZ of the base metal when this zone becomes hard and brittle due
to rapid cooling after the weld metal has been deposited & sufficient hydrogen has been
absorbed by the weld metal from the arc atmosphere.
Precaution: -
  1. Use of low carbon equivalent materials.
  2. Higher heat input during welding.
  3. Preheating.
  4. Use of low hydrogen electrode.
  5. Faulty weld size and profile
A weld is considered faulty if it has lack of reinforcement, excessive reinforcement or irregular
Profile.
  1. Distortion
Because a weldment is locally heated (by most welding processes), the temperature
distribution in the weldment is not uniform and changes take place as welding processes.
Typically, the weld metal and the base metal heat-affected zone immediately adjacent to it are
at a temperature substantially above that of the unaffected base metal. As the molten pool
solidifies and shrinks, it begins to exert shrinkage stresses on the surrounding weld metal and
heat-affected zone area. When it first solidifies, this weld metal is hot, relatively weak, and can
exert little stress. As it cools to ambient temperature, however, the shrinkage of the weld metal
exerts increasing stress on the weld area and eventually reaches the yield point of the base
metal and the heat-affected zone. Residual stresses in weldments have two major effects. First,
they produce distortion, and second, they may be the cause of premature failure in weldments.
Distortion is caused when the heated weld region contracts no uniformly, causing shrinkage in
one part of the weld to exert eccentric forces on the weld cross section.
The distortion may appear in butt joints as both longitudinal and transverse shrinkage or
Contraction, and as angular change (rotation) when the face of the weld shrinks more than the
root.
Distortion in fillet welds is similar to that in butt welds: transverse and longitudinal shrinkage as
well as angular distortion results from the unbalanced nature of the stresses in these welds.

8. Q:- What is mean by ‘PWHT’? Why it is required?

Answer: -
“POST WELD HEAT TREATMENT” This is done to remove residual stress left in the joint which may
cause brittle fracture.

Answer:-
The low hydrogen electrodes have in their coating ingredient, which produces carbon di-oxide during
melting. This CO2 gives a gaseous shielding for the metal and prevents atmospheric hydrogen from
entering in arc atmosphere. By this way the weld metal has low level of hydrogen.

What Books Recommended to Study for CWI Test?

What Books Do I Need to Study for CWI Test? 

I would suggest the "Welding Inspector's Handbook" available from American Welding Society AWS. If you take the American Welding Society Certified Welding Inspector Training seminar, you will be given a stack of books to study.

If you don't take the CWI Training seminar, Buy the following books:

  • Welding Inspection Technology and Workbook
  • AWS A2.4 Welding and NDT Symbols
  • AWS A3.0 Terms and Definitions
To pass the CWI Exam, you will need to get 72% marks from Each Part.
Go to the AWS American Welding Society website, they have downloadable versions of Part B, and other aids.  Click Here to Downloads Free AWS CWI Books from American Welding Society online bookstore
There is lots of welding symbols questions, maybe 16. So know those cold. Lots of questions on welding processed, too.
You will have to know how to use a micrometer and dial caliper
Calculate cross sectional area of a round and rectangular piece.
Calculate ultimate tensile strength, elongation, and reduction in area using both US customary units as well as metric conversions.
The hard part will be to identify various weld discontinuities using plastic weld replicas and measure weld sizes, undercut, etc.
You will be provided with a "welding standard" that is a compilation of AWS D1.1, ASME Section IX, and a little API thrown in for good measure. The trick is to read the specification without allowing your day to day experience influence your decision on accepting or rejecting welds.  Use only the criteria listed in the specification.
I understand it used to be harder, with much more math. The one week immediately preceding the tests is invaluable. They really drum it into your head.
The AWS CWI Training Seminar is definitely worth it. And then the one week class AWS CWI gives right before the test is excellent.
There are three parts of tests involved, and they have to be completed in 2 hours each part. The first part is (Part A) General Knowledge and is 150 questions closed book.
The second part is Part B, The Part B is practical test. Part B is the accumulate welding standard GTAW referral. This is where most candidates who miss the test mess up. Part of the reason is the samples are pretty beat up and may confuse candidates. With the good preparation it will go well. Another part is if you have so many years of experience in inspecting, it may well work against you. As GTAW mentions, accept or reject based on the supplied test only. Some of the porosity is unbelievably huge, but depending on the criteria is acceptable.
The third is Part C, The Part C is your Code section. I tested with API 1104 (Welding of Pipelines and Related Facilities) and it sounds like you will be also. Both Part B and Part C is open book, so memorization of formulae won't be an issue.

Q:- Why is it essential to clean the surrounding parent metal adjacent to the weld metal made by MMA(SMAW)which is to be ultrasonically tested?


  1. Sound waves will not travel though paint 
  2. Remove any rust 
  3. The spatter will impede the contact of the probe and the parent material surface 
  4. Spatter will reflect the back will echo signal and give spurious indications 

Sunday 12 February 2017

Q:- While inspecting a weld on a 100mm thick high carbon steel plate with tolerance of +5mm you find the weld is visual acceptable, however the parent material has several arc strikes present adjusted the weld approximately 3mm drop deep, what course of action would you take?

1. None I am only inspecting the weld
2. Recommended that the area be dressed smooth
3. Recommended that the area be dressed smooth followed by MPI
4. High carbon steel is net susceptible to cracking so I would weld over the arc strikes then blend them
