welding processes

100

This common arc welding process uses a consumable electrode and shielding gas. MIG welding? (or Gas Metal Arc Welding)

gas metal arc welding

200

This process uses a non-consumable tungsten electrode and requires a shielding gas. TIG welding? (or Gas Tungsten Arc Welding)

gas tungsten arc welding

300

This process is often used outdoors and uses a flux-coated electrode. Stick welding? (or Shielded Metal Arc Welding)  

shielded metal arc welding

400

This high-energy process is commonly used in manufacturing and aerospace, often with automation.

laser welding

500

This process uses a wire that continuously feeds and a flux core instead of shielding gas.

flux corded arc welding

Weld Defects

100

This defect occurs when the weld does not penetrate fully.

lack of penetration

200

These small holes in a weld are caused by trapped gas.

porosity

300

This defect is caused by improper fusion between the base metal and the weld.

lack of fusion

400

This crack-like defect can occur when welding thick sections too quickly.

hot cracking

500

This term describes metal that has been deposited outside the weld zone.

spatter

Metals & Materials

100

This is the most commonly welded metal.

steel

200

This metal is lightweight, corrosion-resistant, and often TIG welded.

aluminum

300

This non-ferrous metal is red in color and a good conductor.

copper

400

This metal is extremely hard and heat-resistant, often used in aerospace.

titanium

500

This term describes the joining of two dissimilar metals.

dissimilar metal welding

Tools & Equipment

100

This tool is used to remove slag after stick welding.

chipping hammer

200

This machine regulates voltage and amperage during welding.

welding power supply

300

This tool is used to hold metal in place while welding.

welding clamp

400

A gas cylinder with a green label typically contains this shielding gas.

oxygen

500

This tool is used to test welds for internal defects using sound waves.

ultrasonic testing equipment

Safety First

100

This protective gear is essential to prevent eye damage from the welding arc.

welding helmet

200

You should never wear clothing made of this material while welding due to fire risk.

polyester

300

This color of lens shade is typically required for most arc welding.

shade 10 or darker

400

This toxic gas can be produced when welding galvanized steel.

zinc oxide

500

This type of ventilation is necessary when welding in confined spaces.
