Arc welding is a fusion welding process that uses an electric arc to produce heat and melt metal. The welder creates an arc between an electrode and the base metal to melt and fuse the metals together. Arc welding is commonly used to weld steel and can also weld other metals like aluminum and copper. It is extensively used in construction and manufacturing due to its versatility and ability to be used in the field without complicated equipment. Basic steps of arc welding involve preparing the materials, choosing the right process and filler, following safety procedures, and inspecting the final weld.

2. Arc Welding
• It is a fusion welding processes which uses an
electric arc to produce the heat required for
melting the metal.
• The welder creates an electric arc that melts the base metals
and filler metal (consumable) together so that they all fuse
into one solid piece of metal

3. Arc Welding
• Many things around us are welded …
– Pipelines that bring fresh water
– Towers that carry electricity to houses
– Cars and buses that take people where they need to go
• Arc welding continues to be used extensively in the construction of
steel structures and in industrial fabrication.
• The process is used primarily to weld iron and steels (including
stainless steel) but aluminium, nickel and copper alloys can also be
welded with this method.
• It dominates other welding processes in the maintenance and
repair industry, and though flux-cored arc welding is growing in
popularity
• Is popular because it can be used in the field without
complicated equipment and gases

9. Basic Steps of Arc Welding
• Prepare the base materials: remove paint and
rust
• Choose the right welding process
• Choose the right filler material
• Assess and comply with safety requirements
• Use proper welding techniques and be sure to
protect the molten puddle from contaminants in
the air
• Inspect the weld
