SAFETY FIRST
This three-letter acronym stands for the equipment used to protect workers from hazards, such as helmets and gloves
What is PPE
In the electrode classification E7018, this is the tensile strength represented by the first two digits.
What is 70,000 psi
This is the common nickname for Gas Metal Arc Welding.
What is MIG Welding?
Unlike SMAW, GTAW uses this type of non-consumable electrode to create the arc.
What is Tungsten?
This is the priority level assigned to "Elimination of the hazard" in the hierarchy of risk controls.
What is Elimination?
To prevent electric shock, welding equipment must be connected to this to provide a safe path for fault current
What is Grounding
This electrode is commonly preferred for deep penetration when welding on dirty or rusty steel.
What is E6010
This specific transfer mode is ideal for welding thin materials to prevent burn-through.
What is Short-circuit transfer?
This inert gas is the primary shielding gas used for most TIG welding applications.
What is Argon?
This specific type of chromium (VI) is a known carcinogen often found in stainless steel welding fumes.
What is Hexavalent Chromium?
This color is the standard for acetylene hoses in oxy-fuel systems in the U.S.
What is Red
To prevent hydrogen-induced cracking, low-hydrogen electrodes like E7018 must be stored in this.
What is a Heated Electrode Oven (Rod oven)
This is a common problem when using GMAW outdoors due to wind.
What is Loss of Shielding Gas?
This type of current is required when welding aluminum with GTAW to clean the oxide layer.
What is AC (Alternating Current)?
In automated systems, these two safety features (sensors and doors) are critical for protecting operators.
What is Presence sensors and interlocked doors?
This permit is required before welding can begin in a flammable or high-risk environment.
What is a Hot Work Permit
This phenomenon, often caused by DC current, involves the deflection of the welding arc from its path.
What is Arc Blow
Increasing this setting on a GMAW machine primarily increases both amperage and the deposition rate.
What is Wire Feed Speed?
This device allows a TIG welder to control the amperage manually while the arc is active.
What is a Foot Pedal?
This is the distance at which an unprotected person may receive a second-degree burn from an arc.
What is arc flash boundary?
This is the maximum acceptable oxygen range required in a confined space before welding.
What is 19.5% to 23.5%
This post-weld treatment is often used to reduce residual stress in critical, high-strength welds.
What is Stress-relief annealing (or Post-Weld Heat Treatment)
This advanced GMAW transfer mode allows for all-position welding with deep penetration at lower average amperage.
What is Pulsed Spray Transfer?
This gas is used inside a pipe during welding to protect the back side of the weld from oxidation.
What is Purge Gas?
This is the classification of laser that requires the strictest eye and skin protection in laser welding.
What is Class 4?
