Question 1: What is the impact of welding on the mechanical properties of a heat-treated material?

Which action should you take?

Choose only one option

It strengthens the material by changing the chemical composition

It has no effect on the mechanical properties as long as the material is heated correctly

It can cause local changes in hardness, toughness, and strength near the weld

It reduces the risk of thermal expansion during cooling

Question 2: How does the choice of filler material impact the performance of the welded joint in metal fabrication?

Which action should you take?

Choose only one option

The filler material should be the same as the base material in color and texture only

It must be compatible with the base metal and contribute to the desired strength and corrosion resistance of the joint

The filler material is irrelevant as long as the weld penetrates the material

Filler material should only focus on cost savings without considering strength

Question 3: How do you ensure the alignment of multiple components when interpreting a blueprint for assembly?

Which action should you take?

Choose only one option

By assuming that no misalignment occurs unless noted in the drawing

By adjusting the components until they appear to fit

By confirming that all dimensions and reference points align across different views

By following the sequence of the assembly process without referencing the dimensions

Question 4: When fabricating a structural steel frame, which of the following is the best method to prevent warping?

Which action should you take?

Choose only one option

Apply a post-weld heat treatment to relieve residual stresses

Use low-carbon steel exclusively for the frame

Weld as quickly as possible to minimize heat input

Use preheating and proper cooling rates to control stress distribution

Question 5: What is the impact of inconsistent arc length in TIG welding?

Which action should you take?

Choose only one option

It increases the speed of the weld but reduces strength

It causes the weld bead to form a convex shape, which is desirable

It has no impact if the filler material is applied correctly

It can result in poor fusion, uneven penetration, and excessive spatter

Question 6: When handling flammable materials in a fabrication shop, what safety protocol should be followed?

Which action should you take?

Choose only one option

Use only non-sparking tools in the workspace

Store the materials in a cool, dry, and ventilated area

Keep the materials near the fabrication area

Store the materials under direct sunlight
