In MMA welding, what parameter is used to control the penetration into the base material?

In the welding of a butt joint made from one side, which of the following controls the profile of the root bead? What type of power source characteristic is required for manual welding? Which of the following destructive test would indicate the toughness of weld metal and parent metal — HAZ? Degreasing components are essential for quality welding but some agents may: a Cause corrosion problems b Give off phosgene gas c Leave residues d All of the above Which of the following chemical elements has the greater effect on the hardenability of a steel plate?

In MIG? CO2 welding which parameters give the greatest control of weld appearance during dip transfer or short circuiting welding? In MMA welding, the slag produced can be varied to suit the welding position.

Which type of slag would be required for welding in the HV position? The weld metal deposit of MMA electrodes, achieves its mechanical strength through: a The core wire b The flux coating c Iron powders with the flux coating What constituent is needed in a coating of an electrode to prevent the formation of porosity in welding of a rimming steel? Welds made with high heat inputs show a reduction in one of the following properties: a Ductility b Toughness c Fatigue strength d Mechanical strength A steel described as QT will have improved tensile properties because it has: a Had control of chemical composition b Been heat treated c Been quality tested d Been vacuum melted Which one of the following type of steels would give rise to the formation of porosity when autogenously welded with an arc process?

The use of cellulosic electrodes is often made when welding the root pass of pipes in the field. This is because: a H2 control is needed b Iron powders in the electrode c Higher arc voltage can be obtained d Shorter arc length can be achieved In the welding of austenitic stainless steels, the electrode and the plate material can be purchased with low carbon contents.

The reason for this is to prevent: a Cracking in the HAZ b The formation of chromium carbides c Cracking in the weld metal d Distortion Submerged arc fluxes can be supplied in two forms.

These are: a Sintered and agitated b Agitated and fused c Crushed and agglomerated d Fused and agglomerated In a steel which has improved creep properties at elevated temperature, which one of the following elements helps in this improvement? Welding a steel plate of a CE of 0. Welding procedures may require welds to be deposited at a controlled rate heat input. High heat input would: a Have poor profile b Have larger grain size c Have high hardness in the HAZ d Have low elongation properties BS part II communicates by the use of symbols the type of joint preparation to be used.

Listed below are four symbols. Which of these indicates the depth of penetration of the weld required on the joint? In accordance with BS what is the weld junction? Which of the following are essential factors for lamellar tearing? In gas welding, leftward welding is described in BS as: a The flame is described towards the welded part and filler material is directed toward un- welded part of the joint b The flame and filler material both directed towards welded part of the joint c The flame is directed towards the un-welded part and filler material is directed towards welded part of the joint d The flame and filler material is both directed towards un-welded part of the joint Which of the following is not a fusion welding process: a Thermit welding b Electro slag welding c Laser welding d Friction welding Which of the following are essential variables for PWHT?

Most metals expand when heated, the change in length is expressed as: a Thermal conductivity b Modulus of elasticity c Coefficient d Yielding Which of the following is the odd out? Which of the following are considered to be HAZ cracks? Which of the following standards entitled Visual inspection of fusion welded joints? In general it is not easy to mechanise the MMA welding process because: a Short electrode length, the control of the arc length and the process uses a flat characteristic b Short electrode length, the control of the arc length and flux coverings c The control of the arc length, stop start problems and short electrode length d Flux coverings, short electrode lengths and relationship between amps and volts Which of the following statements is true?

Which of the following best describes a semi automatic welding process? Which material is the most susceptible to reheat cracking? Three essential factors for producing fusion weld are melting, removal of surface oxide from the joint surfaces and elimination of atmosphere from the region of the arc.

Name the fourth one: a The weld must be free from stress b The filler material must match that of the weld c The completed joint must at lease match the mechanical properties d An arc for a heat surface Which arc welding process technique is likely to be used to repair localized porosity in a weld?

Planar defect are best described as: a Linear from at least one direction b Rounded indications c Linear from at least one direction with volume d May be classed as all of the above Which of the following welding processes is not classed as an arc welding process?

Which of the following materials has the poorest weldability? Which of the following in a fusion weld usually has the highest tensile strength? Which of the following is an alternative name for a crater crack? What action must the welding inspector request if a lamination is found extending into the bevel face?

Which of the following heat treatment processes would be used for grain refinement? A repair has been made using MMA on a double V butt weld on a 10 m diameter tank. The defect repaired was lack of inter-penetration and it had been excavated with a disc grinder prior to repair. After repair it was determined that the wrong electrodes had been used.

What action should the inspector take: a Have the repair area ground and re-repair b Accept the work if the electrodes were the same flux type c Heat treat the area d Consult the senior inspector or welding engineer if the specification or procedure does not cover the course of action Which one of the following statements is false?

What is the possible cause of too mush restraint of the parent material during welding? Fluctuating loads ie cyclic stresses below the u.

Which of the following is a method to accurately measure the root radius of a charpy or izod specimen? Which of the following is not an inert gas at welding temperature? Which arc welding process uses a non consumable electrode? Which of the following welding processes is not a fusion welding process? Which of the following current types would be used for welding aluminum with the TIG welding process?
