CERTIFIED WELDING INSPECTOR QUESTIONS AND ANSWERS 2024.

Abrasion Soldering A soldering process variation during which faying surface of the base metal is mechanically abraded. Abrasive Blasting A method of cleaning or surface roughening by a forcibly projected stream of abrasive particles. Brainpower Read More 0:01 / 0:15 Absorptive Lens A filter lens designed to attenuate the affects of glare, reflected light and direct light. Accelerating Potential (electron beam welding/cutting) The potential imparting velocity to the electrons. Acetylene Feather The intense white, feathery edged adjacent to the cone of a carbonizing oxyacetylene flame. Acid Core Solder A solder wire or bar containing acid flux as a core. Activated Rosin Flux a rosin-based flux containing an additive that increases wetting by the solder. Active Flux (SAW) Submerged Arc Welding- a flux formulated ot produce a weld metal composition dependent on the welding parameters, especially arc voltage. also see alloy flux and neutral flux. Adaptive Control Pertaining to process control that automatically determines changes in process conditions and directs the equipment to take appropriate action. Adaptive Control Welding/brazing/soldering/thermal spraying Welding with a process control system that automatically determines changes in welding conditions and directs the equipment to take appropriate action. Adhesive A polymeric material having chemical and physical properties differing from those of the base materials, placed at their faying surfaces, to join the materials together as a result of the attractive forces of this polymeric material. Adhesive Bond An attraction. Generally physical in nature, between an adhesive and the base materials. Adhesive Bonding A joining process in which an adhesive, placed between faying surfaces, solidifies to produce an adhesive bond. Agglomerated Flux (SAW) Submerged Arc Welding- A granular flux produced by baking a pelletized mixture of powered ingredients and bonding agents at a temperature sufficient to remove the water, followed by processing to produce the desired particle size. Also see bonded flux and fused flux Air Acetylene Welding (AAW) An oxyfuel gas welding that uses an air-acetylene flame. The process is used without the application of pressure. This is an obsolete or seldom used process. Air Carbon Arc Cutting (CAC-A) A carbon arc cutting process variation removing molten metal with a jet of air. Air Carbon Arc Cutting Torch A device used to transfer current to a fixed cutting electrode, position the electrode, and direct the flow of air. Air Feed A thermal spraying process variation in which an air stream carries the powdered surfacing material through the gun and to the heat source. Aligned Discontinuities Three or more discontinuities aligned approximately parallel to the weld axis. Spaced sufficiently close together to be considered a single intermittent discontinuity. Aligned Porosity A localized array of porosity oriented in a line. Alloy A substance with metallic properties and is composed of two or more chemical elements (of which at least one is a metal). Alloy Flux (SMAW) A flux containing ingredients that react with the filler metal to establish a desired alloy content in the weld metal. Alloy Powder Powder prepared from a homogeneous molten alloy or from the solidification product of such an alloy. Arc Blow The deflection of a welding arc from its normal path because of magnetic forces. Arc Brazing Welding (ABW) A braze welding process variation that uses an electric arc as the heat source. Arc Cutting A group of thermal cutting processes that severs or removes metal by melting with the heat of an arc between an electrode and the workpiece. Arc Cutting Gun A device used to transfer current to a continuously fed cutting electrode, guide the electrode and direct the shielding gas. Arc Force The axial force developed by an arc plasma. Arc Gouging Thermal gouging that uses an arc cutting process variation to form a bevel or groove. Arc Length The distance from the tip of the welding electrode to the adjacent surface of the weld pool. Arc Plasma A gas that has been heated by an arc to at least a partially ionized condition, enabling it to conduct an electric current. Arc Seam Weld A seam weld made by an arc welding process. Arc Spot Weld A spot weld made by an arc welding process. Arc Spraying A thermal spraying process using an arc between two consumable electrodes of surfacing materials as a heat source and a compressed gas to atomized and propel the surfacing material to the substrate.
