What is the maximum temperature that the base metal can be a

What is the maximum temperature that the base metal can be at while it is being wielded? 50 degree F (10 degree C) 100 degree F (38 degree C) 150 degree F (65 degree C) 350 degree F (175 degree C) Why are the GMA and FCA welding processes used? They both use the same filler metal They can rapidly produce high-quality welds FCA welding is the preferred process because it is better and faster than GMA welding Because once you are certified to make GMA welds, you are automatically certified to make FCA welds too. What is the minimum temperature that the joint must be at before welding can begin? 70 degree F (21 degree C) 60 degree F(15 degree C) 50 degree F (10 degree C) 40 degree F (4 degree C) What is the maximum width of the weld cover pass? 3/32-in (2.4 mm) 1/8-in (3 mm) 1/4-in(6mm) 1/16-in (1.6 mm) How wide of a band next to a groove face must be cleaned of slag, rust, and mill scale? 1 in (25 mm) 1/2 (13 mm) 1/8 in (3 mm) 3/4 in (19 mm) What is the approximate size that the root face on a beveled edge should be ground to? 1/64-in (0.4 mm) to 1/32-in (0.8 mm) 1/16-in(1.6mm)to 1/8-in(3 mm) 1/4-in (6 mm) to 5/16-in (8 mm) 0-in (0 mm) Which of the following would not be part of the information that would be included on a qualification test? filler metal shielding gas type of joint right or left handed welder

Solution

14.b

A high level of accuracy generally is not required for preheating carbon steels. Although it is important that the work be heated to a minimum temperate, it is acceptable to exceed that temperature by approximately 100°F (40°C)

there are instances where it would benefit the fabricator to utilize a joint design that features a bevel and a root face(with no gap).
