Presentation transcript:

Arc Welding Mr. Lombardi

Arc Welding ► ► Arc welding uses a power supply to create an electric arc between an electrode and the base material. ► ► The arc creates the heat to melt the metals at the welding point.

Arc Welding ► ► One of the most common types of arc welding is shielded metal arc welding (SMAW), which is also known as manual metal arc welding (MMA) or stick welding.

Stick Welding

Stick Welding Parts

Protective Clothing ► ► When welding, the operator must wear protective clothing and tinted colored goggles ► ► Without a welding mask the brightness of the weld area leads to a condition called arc eye in which ultraviolet light causes the inflammation of the cornea and can burn the retinas of the eyes.

Protective Clothing

Arc Welding Mask ► ► Much darker than a gas welding shield ► ► Designed to block ultraviolet light
