very slow process. Requires a high skill level
Oxy-acetylene welding
What type of processes?
Products?
Key features?
Scale of production?
What type of processes: addition
Products: weld mild metal sheets or tubes
Key features: uses a steel filler rod
Scale of production: small scale production
Used in repair shops as no electricity isn’t required
Spot welding
What type of processes?
