What is an electric arc welder used for?

Back

An electric arc welder is used to weld metal.

Front

Which type of welding is most suitable for outdoor work due to its wind resistance?

Back

Stick welding is most suitable for outdoor work due to its wind resistance.

Front

What type of arc welder should be used when electrical power is not available?

Back

An oxyacetylene welder should be used when electrical power is not available.

Front

What is the primary function of arc welders in construction and repair?

Back

Arc welders are used for melting and joining the edges of metal pieces.

Front

Which welding process uses a consumable wire electrode?

Back

MIG welding uses a consumable wire electrode.

Front

Define MIG welding.

Back

MIG (Metal Inert Gas) welding is a welding process that uses a continuous wire feed as an electrode and an inert gas to protect the weld from contamination.

Front

What is the main advantage of using Stick welding outdoors?

Back

The main advantage of Stick welding outdoors is its resistance to wind, which allows for stable arc formation.

Front

What is the difference between AC and DC welding?

Back

AC (Alternating Current) welding alternates the direction of current, while DC (Direct Current) welding maintains a constant direction, providing more stable arcs.

Front

What materials can be welded using oxyacetylene welding?

Back

Oxyacetylene welding can be used to weld various metals, including steel, aluminum, and copper.

Front

What safety equipment is essential when welding?

Back

Essential safety equipment includes a welding helmet, gloves, protective clothing, and safety glasses.
