Welding Level 2, Module 7 questions and answers

flux A shielding gas can be generated entirely from the ____________________ in the electrode core. (self shielded FCAW-S) rear deflector material If a hard hat is required for the environment, use one that allows the attachment of ____________________. flash sheids When preparing to practice welding, set up ____________________ around the welding area. 30 to 37 1/2 V-groove weld coupons must be beveled at _________to___________degrees for carbon steel or low alloy plate. deeper Slower travel speeds build higher beads with ____________________ penetration. push angle A ____________________ is the travel angle created when the welding gun is tilted back so that the electrode tip precedes the gun in the direction of the weld. increases Changing the extension influences the welding current for low conductivity metal electrodes because it changes the preheating of the electrode caused by the resistance of the electrode to current flow. As the extension increases, preheating of the electrode ____________________. Stickout ____________________ is the distance from the insulating nozzle to the end of the electrode. full cross section When making a termination, the welding codes require that the crater must be filled to the ____________________ of the weld. padding Overlapping beads are made by depositing connective weld beads parallel to one another. The parallel beads overlap, forming a flat surface. This is also called ____________________. Convexity _____________________ is the distance the weld extends above the line drawn between the toes of the weld. travel speed Increase of decrease the ____________________ to control the amount of weld metal build-up. stainless steel Avoid using weave beads for ____________________. zigzag When practicing vertical (3G) position V-groove welds, use a ____________________ weave pattern. uniform When practicing overhead (4G) position V-groove welds, the weld is acceptable if it has a ____________________ weld width of plus or minus 1/16 of an inch.
