48- WELDING AND INSPECTION TERMS WITH VERIFIED SOLUTIONS ALREADY GRADED A+.

Coalescence is a) the same as fusion b) a type of coating used on a welding rod c) a term used in brazing d) a term used in soldering e) the mixing of gases in a cutting torch A When heat from electric current and pressure are used in welding, it is known as a) resistance welding b) forge welding c) submerged arc welding d) MIG welding e) TIG welding A Brainpower Read More 0:04 / 0:15 Slugging is a term which refers to a) creation of a gas pocket created by gas or moisture trapped in the weld b) solid non-metallic material trapped in the weld c) stresses built up in a structure as a result of welding d) metal particles being sprayed out during the welding process e) adding pieces of unspecified rod or metal as filler during a weld E A "reducing flame" is one which is a) rich in acetylene b) placed an increased distance from the work c) oxygen rich d) held perpendicular to the weld axis e) most likely to cause backfire A Gas pockets trapped within a weld is commonly called a) flux b) porosity c) spatter d) slugging e) fusion B Destructive testing of a weld means a) destruction of one complete weld of a structure or vessel b) destruction of the complete vessel after construction c) mechanical testing of a sample or small portion of a weld d) raising hydrostatic pressure on a vessel to the point of rupture e) thermal shocking a vessel to the point of fracture C The best method of weld inspection if error is to be avoided is the a) visual method b) fluorescent penetrant method c) ultrasonic method d) dye penetrant method e) radiographic method A When an ultraviolet light is used in weld inspections, the testing method is a) destructive b) dye penetrant c) ultrasonic d) radiographic e) fluorescent penetrant E The basic difference between fluorescent penetrant and dye penetrant is that dye penetrant a) makes valuable use of penetrameters b) uses less compounds than fluorescent c) involves the use of a developer compound d) cannot be reliable in locating porosity in a weld e) requires a "black" light to detect cracks C When penetrameters are used for testing welds, the method being used is the a) dye penetrant b) ultrasonic c) fluorescent penetrant d) radiographic e) visual D When using radiographic inspections, defects such as cracks and porosity show up as a) lighter shadows on the photographic paper b) wave signals on a small screen c) darker shadows on the penetrameter d) darker shadows on the photographic paper e) lighter shadows on the penetrameter D Add or Remo
