Study Notes

SMAW Unit of Study Overview

The main focus of the SMAW Unit of Study is on Shielded Metal Arc Welding.

Safety Precautions

Information about safety precautions for welding, cutting, and allied processes can be found in the ANSI Z49.1:2005 standard.
Safety precautions in SMAW are supplemental and do not replace other safety information.
Warning labels related to welding equipment and consumable packaging can be found on the equipment and packaging.
If you have any questions about safety while welding, ask.

SMAW Process

The primary purpose of using ventilation or exhaust in SMAW is to remove welding fumes and gases.
Receiving an electric shock in SMAW can cause serious injury or death.
The flux coating on the electrode in SMAW protects the arc and weld area from atmospheric gases.
The shielding gas in SMAW protects the weld puddle from contamination during its molten state.
The part of the electrode that becomes part of the weld in SMAW is the metal core.
When the electric arc is established in SMAW, the metal core melts and forms a weld pool.
A welder is primarily focused on maintaining the correct arc length and travel speed while welding in SMAW.
The shielding gas protects the weld puddle from contamination during its molten state in SMAW.
When the molten weld puddle solidifies in SMAW, it forms a strong bond between the metal pieces.
