All of the above it depend upon the leg length size
Reducing the grain size
Increasing the heat input
Reducing the heat input
Both a and b
It's destructive test used to assess material ductility in the weld zone
It's a mechanical test used to determine a welds resistance to creep
It's destructive test, which is used to give a measure of notch toughness
It's a static test used to determine material toughness in the notch region
Both a and c
The EN/ISO weld symbol will always have the arrow side weld at the top of the reference line
The EN/ISO weld symbol has the welds elementary symbol placed on a dached line lying above or below the solid reference line to indicate a weld on the other side
The EN/ISO weld symbol has a fillet weld leg length identified by the letter "a"
The EN/ISO weld symbol has a fillet weld throat thickness identified by the letter "z"
Both b and d
Low toughness,entrapped hydrogen and low hardness
High hardness,lack of fusion and entrapped hydrogen
Entrapped hydrogen ,low toughness and high ductility
Lack of fusion ,low toughness and reduction in ductility

A basic electrode depositing weld metal with yield strength af a least 70,000 psi
Both a and d
The welding process is stated as MMA
The welding process is stated as TIG
The welding process is stated as SAW
NDT is to e carried out after welding
None of the above

AC
Both a and b
Control the rate of spatter in the dip transfer mode
It enable the welder to weld in position with the spray transfer mode
It allows for thicker filler wires to be used(2.6-3.6mm diameter)
It allow full control over droplet size in the spray transfer mode
Decreases weld pool fluidity
Requires more heat to melt it when compared to aluminium
Causes the welder to travel to quickly
The presence of the oxide makes aluminium impossible to weld
Copper inclusion and excessive cap heights
Excessive root penetration and porosity
Slag inclusion and crater pipe
Lack of fusion and poor cap profiles
Ensure good penetration
To prevent the arc striking on the parent material
To help prevent the formation of crater pipe and possible cracking
To help prevent tungstan inclusion during welding
Increasing the cutting speed
The use propane as a fuel gas
Pre heating the material to be cut
All of the above
100% argon
100% CO2
75% argon +25% CO2
All of the above would give the same depth in penetration
An arc gap,which remains almost constant even if as usual the welder varies the position of the electrode
A voltage ,which remains almost constan even if as usual the welder ,varies the arc gap
A current ,which remains almost constan even if as usual the welder ,varies the arc gap

The welder is responsible for the maintaining the arc gap and travel speed
The welder is responsible for travel speed only;arc gap is kept constant by the welding plant
Both travel speed and arc gap is controlled by the welding plant
All of above
To keep the arc stable when using low current settings
To convert AC current to DC current
To convert DC current to AC current
To initiate arc at start up
