- What does welding use to join metal parts?
Show the answer
High heat to melt the parts together. Welding joins materials by melting the parts with high temperatures, then letting them cool and fuse.
- How is welding different from soldering and brazing?
Show the answer
It melts the base metal. Soldering and brazing do not melt the base metal, but welding does melt the parts being joined.
- Why is a filler material often added to a weld?
Show the answer
To form a molten pool that becomes the joint. Filler metal forms a molten pool that cools into a joint that can be stronger than the base material.
