Welding safety
What piece of safety equipment protects your eyes and face from sparks and UV light while welding?
Welding helmet
What tool holds the welding electrode during stick welding?
Electrode holder
What welding process uses a consumable electrode coated in flux?
Stick welding (SMAW)
What welding position is performed on a flat surface?
Flat position
What term describes how well the weld fuses to the base metal?
Penetration
What should you always wear on your hands while welding to prevent burns?
Welding gloves
What tool is used to remove slag from a weld?
Chipping hammer
Which welding process uses a wire fed continuously through a gun?
MIG welding (GMAW)
What welding position is done on a vertical surface?
Vertical position
What defect occurs when the weld metal sits on top without bonding?
Lack of fusion
Why should loose clothing not be worn while welding?
It can catch fire or get caught in equipment
What machine component controls the amount of electrical current used for welding?
Amperage control
What welding process is known for producing very clean and precise welds?
TIG welding (GTAW)
What position requires welding from underneath the workpiece?
Overhead position
What causes porosity in a weld?
Contamination or trapped gas
What gas is commonly used in welding areas that can be dangerous if ventilation is poor?
Welding fumes / shielding gases
What type of clamp is used to complete the electrical circuit during welding?
Ground clamp
Why is shielding gas important in MIG and TIG welding?
Why is overhead welding more difficult than flat welding?
Gravity affects molten metal
How can improper amperage affect weld quality?
It can cause weak or uneven welds
Why is proper grounding important for welding safety?
It prevents electrical shock and ensures a stable arc
What tool is used to clean metal before welding to improve weld quality?
Wire brush or grinder
Which welding process is best suited for thin metals and aluminum?
TIG Welding
Which welding position is considered the most challenging and why?
Overhead, due to gravity and control of the weld puddle
What steps can be taken to prevent weld defects?
Proper settings, clean metal, correct technique
