BOOK 3 CHAPTER 15 WELDING TERMS AND INSPECTION QUESTIONS AND ANSWERS.

The item which keeps the weld from oxidizing, cooling too fast and the beads smooth during submerged arc welding is the Flux The basic difference between fluorescent penetrant and dye penetrant is the fluorescent penetrant Requires a black light to detect cracks Brainpower Read More 0:01 / 0:15 Procedure qualification means that a welder can 1. Preformed only a specific type of weld. 2. Be tested any time the inspector requests. 3. Be tested before doing a specific weld type. Examples of nondestructive testing are Dye penetrant, radiographic and ultrasonic Nondestructive testing of a weld could mean Subjecting the weld to a radiographic inspection When heat from electric current and pressure are used in welding, it is known as Spot welding The information that a boiler manufacturer must supply in order to get a welding procedure qualified includes 1. The type of welding process. 2. Electrode specifications. 3. Type of heat treatment. When a weld pass is made to deposit a backing weld behind the route pass, it is termed A backing pass Coalescence is The same as fusion Which is not a common hazard of welding Hearing damage With regards to welding, a procedure qualification means that a welding procedure Meet the applicable code provisions A certificate of competency for a pressure welder is usually valid for a period of 18 months maximum Personal protective equipment for welders includes 1. Proper Eye protection. 2. Safety shoes. 3. Heavy dark clothing. 4. Flame proof gloves. 5. Hardhat or skullcap. When penetrameters are used for testing welds, the method being used is the Radiographic Which of the following would be appropriate eye protection for welding Welding helmet Regarding weld testing, what is the purpose of a tensile test It is used to determine whether or not a weld specimen has the minimum required ultimate strength. Who is responsible for the welding done by a welder on a job site The welders employer What type of weld defects can a fluorescent penetrant or dye penetrant test detect Defects that reach the surface What must a power engineer ensure before allowing any welding to take place in one of his or her vessels 1. The equipment must be isolated. 2. The equipment must be free of combustible or dangerous gases. 3. Low voltage lighting must be provided. Ultrasonic inspection involves the use of High-frequency vibrations Braze Is To solder with a nonferrous alloy that melts at a lower temperature than that of the metal being joined Coalescence Unites two pieces of metal into one
