CRAW certification sample questions
Tap any question below to reveal the answer and a plain-English explanation.
Symbols Welding Robotics Which component of a welding symbol indicates the side of the joint on which the weld is to be made?
A. The weld symbol
B. The reference line
C. The tail
D. The arrow ✓
Correct — D. The arrow in a welding symbol points to the joint and indicates the arrow side of the joint. Welds specified on the arrow side are shown below the reference line, while welds on the other side are shown above the reference line.
Definitions Terminology What does the acronym GMAW stand for in robotic welding?
A. Gas Mixture Arc Welding
B. General Metal Arc Welding
C. Gas Metal Arc Welding ✓
D. Guided Motion Arc Welding
Correct — C. GMAW (Gas Metal Arc Welding) is a common welding process used in robotic applications that uses a consumable wire electrode and shielding gas.
Weld Examination What is the primary purpose of visual weld inspection in robotic arc welding?
A. To measure exact penetration depth
B. To determine internal weld strength
C. To identify surface defects and verify weld profile ✓
D. To calculate the heat-affected zone dimensions
Correct — C. Visual inspection is the first and most common method of weld examination, used to identify surface defects and verify weld profile before any other testing methods are applied.
Weld Equipment Setup What is the primary purpose of performing a Tool Center Point (TCP) calibration on a robotic welding system?
A. To update the robot's operating system
B. To increase the robot's maximum speed capability
C. To establish the exact position of the welding torch tip in the robot's coordinate system ✓
D. To reduce power consumption during welding
Correct — C. TCP calibration establishes the precise location of the welding torch tip in relation to the robot's coordinate system, which is essential for accurate positioning during welding operations.
Symbols Welding Robotics In a robotic welding program, which symbol typically represents a linear interpolation movement?
A. J
B. C
C. L ✓
D. P
Correct — C. In robotic programming, an 'L' symbol typically represents linear interpolation, where the robot moves in a straight line from one point to another at a controlled speed.
Definitions Terminology What is the term for the point on a robot welding torch around which the robot moves and orients the tool?
A. Working Reference Point (WRP)
B. Tool Center Point (TCP) ✓
C. Torch Alignment Point (TAP)
D. Motion Control Origin (MCO)
Correct — B. TCP (Tool Center Point) is a critical reference point in robotic welding that defines the location around which the robot positions and orients the welding torch.
Weld Examination Which of the following defects is characterized by a gap or space within a weld?
A. Undercut
B. Porosity ✓
C. Overlap
D. Misalignment
Correct — B. Porosity refers to gas pockets or voids that form within the weld metal during solidification, creating gaps or spaces within the weld structure.
Weld Equipment Setup Which component should be checked first when setting up shielding gas for a robotic GMAW welding system?
A. Gas cylinder manufacturing date
B. Gas lines for leaks ✓
C. Gas mixture certification paperwork
D. Color coding on the cylinder cap
Correct — B. Before welding operations can begin, the gas lines must be checked for leaks to ensure proper shielding gas delivery and prevent potential quality issues or safety hazards.
