Question 1 of 5

Welding is a high-temperature process that involves melting the base metals in the objects to be joined to fuse them together. A filler metal is used to provide additional material to make up a joint that, depending on the weld type, can be stronger than the base materials alone. Oxyacetylene welding is a welding process that uses a torch fueled with oxygen and acetylene gases. Electric-arc welding utlizes electric current in a safer welding process (it doesn't involve burning explosive gases) that enables a wide variety of specialized applications like stick, MIG (metal inert gas), and TIG (tungsten inert gas) welding.

Which of the following statements about welding is not true?

welding is done at higher temperatures than soldering

no filler metal is required when welding

electric-arc welding is safer than oxyacetylene welding

a weld can often be stronger than the base materials alone
