The part must be preheated to above 350°F (175°C) before welding starts. The welding machine needs to be set on its maximum amperage setting. Make the molten weld pool as large as possible so it will melt all the way through. The edges of the weld plate or pipe must have some type of groove made before welding. ____ can ensure 100% joint fusion at the root and remove discontinuities of the root pass. Tack welding Single bevels Double bevels Back gouging In a(n) ____ joint the metal surfaces are placed together so the edges are even. edge outside corner tee lap Which type of weld joint can be fitted together so that the joint forms a V-groove or square butt joint? Butt Tee Outside corner Edge In the ____ position, the pipe is parallel to the horizon and the weld is made vertically around the pipe. inclined with a restriction ring 6GR horizontal fixed 5G vertical 2G inclined 6G What does the term faying surface relate to? The surface of a joint that will be melted during the weld. The frayed edges of welder's pants, shirt, or other clothing. The surface that cannot be seen directly such as the inside of a pipe weld joint. It is the outside of the pipe or sides of a weld joint that have been cleaned for welding. In a(n) ____ joint the edges of the metal meet so that the thickness of the joint is approximately equal to the thickness of the metal. tee lap butt outside corner When the length of a seam weld is indicated on the symbol, it is shown ____ the weld symbol. to the left of to the right of above below If a welder is not engaged in the specific process of welding for which he or she is qualified for a period exceeding ____, the welder must requalify. two months six months one year two years What might happen if you do not have the most recent version of a code? Codebooks get dirty in the welding shop and older ones are often hard to read. The agencies offering the code move from time to time and you may not be able to find them if you do not have the current code. Codes change from time to time and not having the current code may mean the weld test you take might not be approved in the new version. Codes have been the same for years and the only value to a new codebook is it may be available on the web as a download and be much cheaper. The shortened term ____ is the most common term used by industry to denote a WPS. welding schedule welding parameters welding specifications welding procedures Which of the following is a consequence of choosing the wrong code or standard for a job?

A(n) ____ may require that a specific code or standard be followed, whereas in ____, the code used is considered to be the standard for the industry and has been in use a long time. local, state, or federal government; standard industrial practices local, state, or federal government; bonding or insuring companies end user, standard industrial practices end user, bonding or insuring companies ____ is a specific grouping number for several classifications of electrodes having similar composition and welding characteristics. Classification number X Filler metal specification number F-number A-number ____ is the ASTM specification for the type and grade of material, including the P-number. Filler metal specification Electrode specification Base metal specification Backing strip material specification Which of the following is true of welding codes and specifications? The selection of the specific code to use is made by the welder. They are guidelines and must be qualified for specific applications by testing. The code and specification ensure the product need not be inspected or tested. A welding code and a welding specification are the same thing. The ____ by the specimen's original area converts the ultimate total load for the specimen to the pounds per square inch (psi) that was required to break the material. minimum load multiplied maximum load multiplied minimum load divided maximum load divided What is unique about being employed at a new job as a welder? You are usually asked to take a welding skills test to get the job. You may be asked to demonstrate your physical strength to handle the heavy material used in most welding shops. If you are the first welder hired, you will be given the job as lead welder. You will have to prove you can stand and weld for 8 hours a day. If the machine being used for the weld does not have an amp meter, a meter must be attached to the welding lead, within ____ ft. of the electrode holder, to get the reading of the amount of current in amps used to make the weld.
