American National Standards Institute (ANSI) - The organization which developed welding symbols. Welding Symbol - Gives details about how the object should be assembled and joined together. Weldment - When two or more pieces are joined by welding. Welding Joints - When pieces of a weldment are assembled, the lines along which their edges and surfaces come in contact. Weld Symbol Arrow Side - The side of the metal which the arrow touches. Weld Symbol Other Side - The opposite surface from t...

If a groove only goes part of the way through the joint, welding in the groove results in what is called what? - partial joint penetration The portion of the edge of a part to be joined by a groove weld that has not been beveled or grooved is called what? - root face For long term cutting or welding of materials containing cadmium, what should you wear? - an approved full-face, supplied-air respirator For an open root V-groove weld, the thickness of the root reinforcement should be no more...

One backing material used in groove welds is what? - Inert gas Single groove weld with metal backing are used for what? - high-strength & high-quality welds When preparing weld coupons for V-groove welds with backing, cut the metal strips so that they are atleast what size? - 1" X 8" To conform with AWS limited thickness test coupon requirements, the weld coupons should be what? - carbon steel that is 3/8" thick Low hydrogen electrodes do not have a heavy gas shield, mainly depend...

Line on a horizontal axis parallel with the earths surface (horizon). Also, is a bubble in a glass vial to check level and plumb. Made from aluminum or magnesium. - Level Line on a vertical axis perpendicular to the earths surface (horizon). - Plumb Preplaced filler metal that is completely fused into the root of the joint during welding. - Consumable Insert Used to measure round stock and to locate the center of the shafts or other round objects. - Vshaped Centering PRIMARY PURPOSE: Check...

This can be used to locate the center of shafts or other round objects. - V-shaped head attachment of a combination square The tool that uses a bubble in a glass vial to check level and plumb is what? - level How is the internal misalignment between two sections of pipe to be welded end to end checked? - using a Hi-Lo gauge When using a chain fall to lift or lower weldment parts, what should you do? - Always secure the chain fall to an overhead structural member with an approved sling. Wh...

Always shut off the circuit breaker before - disconnecting the welding machine. Inspect your fall protection equipment before each use. - DC current is produced when - a engine powered welding machine turns a generator. Inverter controlled welding machines offer - a very smooth and steady DC welding arc and are smaller and lighter powered sources. Duty cycle and rated amperage is how - the capacity of a arc welding machine is determined. Welding leads that have a quick disconnect end on t...
