CWB Module 4 Welding Process and Equipment exam | Questions and Verified Solutions 2024/2025 | Graded A+ Active Flux - Answer -significantly influence the weld puddle - add manganese, silicon, chromium to weld metal - typically bonded type flux Arc Blow - Answer -The deflection of an arc from its normal path due to magnetic forces. Autogeneous Weld - Answer -A fusion Weld made without filler metal Duty Cycle - Answer -The time during a ten-minute test period, expressed in percentage, that a power source can operate at the rated output without overheating Fused Flux - Answer -A granular flux produced by mixing the ingredients, followed by melting, cooling to the solid state and processing to produce the desired particle size Heat Affected Zone (HAZ) - Answer -The portion of the base metal adjacent to a weld which has not been melted, but the metallurgicalmicrostructure and mechanical properties have been changed by the heat of welding, sometimes with undesirable effects. Neutral Flux - Answer -make minimal changes to the weld pool composition Non Consumable Electrode - Answer -An electrode that does not provide filler metal What are the eight categories that welding processes are grouped as? - Answer -Arc Welding (AW) Solid State Welding (SSW) Resistance Welding (RW) Oxyfuel Gas Welding (OFW) Soldering (S) Brazing (B) Other Wleding Allied Processes (ie cutting & Thermal Spraying) What are the two main methods of Arc Shielding? - Answer -Flux Shielding
