#1
What type of hazard is associated with welding fumes?
Chemical hazard
ExplanationChemical hazard due to the presence of toxic substances in welding fumes.
#2
What should be worn to protect the eyes when welding?
Safety goggles
ExplanationSafety goggles protect the eyes from sparks, debris, and harmful radiation.
#3
Which gas is commonly used in MIG welding?
Argon
ExplanationArgon is often used as a shielding gas in MIG welding.
#4
What is the purpose of a welding helmet?
To protect the face and neck from burns
ExplanationA welding helmet shields the face and neck from heat and sparks.
#5
What is the purpose of a chipping hammer in welding?
To clean slag from the weld
ExplanationChipping hammers remove slag, allowing for clean and precise welds.
#6
What is the purpose of a ground clamp in welding?
To provide a path for the welding current
ExplanationA ground clamp completes the electrical circuit, allowing the welding current to flow safely.
#7
What does PPE stand for in the context of welding safety?
Personal Protective Equipment
ExplanationPPE refers to equipment worn to minimize exposure to hazards.
#8
What is the purpose of ventilation in welding areas?
To remove fumes and gases
ExplanationVentilation ensures the removal of hazardous fumes and gases from the workspace.
#9
What is the recommended distance between a welding area and flammable materials?
At least 10 feet
ExplanationA minimum distance of 10 feet reduces the risk of fire hazards.
#10
What is a common symptom of welder's lung?
Coughing and shortness of breath
ExplanationWelder's lung often presents with coughing and breathing difficulties due to exposure to welding fumes.
#11
What is the purpose of a welding blanket?
To protect nearby surfaces from sparks and spatter
ExplanationWelding blankets prevent damage to adjacent surfaces from sparks and molten metal.
#12
Which welding process typically produces the highest heat?
Arc welding
ExplanationArc welding generates intense heat suitable for welding thick materials.
#13
Which type of welding involves using a filler material?
Arc welding
ExplanationArc welding uses a filler material to join metals.
#14
What is the purpose of pre-heating the base metal in welding?
To make the metal easier to weld
ExplanationPre-heating reduces the risk of cracking and makes the metal more malleable for welding.
#15
What is the primary danger associated with welding in confined spaces?
Asphyxiation
ExplanationWelding in confined spaces can lead to oxygen depletion, causing asphyxiation.
#16
Which type of welding process uses a consumable electrode that also serves as the filler material?
MIG welding
ExplanationIn MIG welding, the consumable electrode doubles as the filler material.
#17
Which type of welding process requires a flux to shield the weld pool from atmospheric contamination?
Arc welding
ExplanationArc welding relies on flux to protect the weld from contamination.
#18
Which type of welding process is commonly used for precision welding of small parts?
TIG welding
ExplanationTIG welding's precise control makes it suitable for welding small, intricate parts.
