welding processes
This common arc welding process uses a consumable electrode and shielding gas. MIG welding? (or Gas Metal Arc Welding)
gas metal arc welding
This defect occurs when the weld does not penetrate fully.
lack of penetration
This is the most commonly welded metal.
steel
This tool is used to remove slag after stick welding.
chipping hammer
This protective gear is essential to prevent eye damage from the welding arc.
welding helmet
This process uses a non-consumable tungsten electrode and requires a shielding gas. TIG welding? (or Gas Tungsten Arc Welding)
gas tungsten arc welding
These small holes in a weld are caused by trapped gas.
porosity
This metal is lightweight, corrosion-resistant, and often TIG welded.
aluminum
This machine regulates voltage and amperage during welding.
welding power supply
You should never wear clothing made of this material while welding due to fire risk.
polyester
This process is often used outdoors and uses a flux-coated electrode. Stick welding? (or Shielded Metal Arc Welding)
shielded metal arc welding
This defect is caused by improper fusion between the base metal and the weld.
lack of fusion
This non-ferrous metal is red in color and a good conductor.
copper
This tool is used to hold metal in place while welding.
welding clamp
This color of lens shade is typically required for most arc welding.
shade 10 or darker
This high-energy process is commonly used in manufacturing and aerospace, often with automation.
laser welding
This crack-like defect can occur when welding thick sections too quickly.
hot cracking
This metal is extremely hard and heat-resistant, often used in aerospace.
titanium
A gas cylinder with a green label typically contains this shielding gas.
oxygen
This toxic gas can be produced when welding galvanized steel.
zinc oxide
This process uses a wire that continuously feeds and a flux core instead of shielding gas.
flux corded arc welding
This term describes metal that has been deposited outside the weld zone.
spatter
This term describes the joining of two dissimilar metals.
dissimilar metal welding
This tool is used to test welds for internal defects using sound waves.
ultrasonic testing equipment
This type of ventilation is necessary when welding in confined spaces.
local exhaust ventilation
