Welding Terms: Review Q&A 2025|
Updated ALL Inclusive
The fusing of two pieces of metal together. Welding
Stringer beads ran one next to another completely filling the pad Pad of beads
The electrical discharge between the electrode and the workpiece that generates the heat
necessary for welding.
Arc
The deposited metal that forms the weld along the joint, appearing as a narrow line or ridge.
Bead
A joint where two pieces of metal are placed edge-to-edge, typically welded along the seam.
Butt Joint
The final pass or layer of weld metal deposited in the welding process to cover the previous
layers.
Cap Pass
A material used to absorb heat from the molten weld metal, speeding up the cooling process.
1
, Chill
The process of applying a layer of material (usually more resistant to corrosion or wear) over a
base material.
Cladding
The process of severing metal, often using tools like a torch or plasma cutter.
Cutting
Changes in the shape or size of the workpiece due to heat during welding, often requiring
corrective measures.
Distortion
A metal or coated material used to conduct electrical current to create the arc in welding.
Electrode
A material used to remove impurities from the surface of metals to be welded, protecting the
molten metal from oxidation.
Flux
The melting together of base metals to form a continuous bond without the use of additional
filler material.
