Question 1:

Two low-carbon steel plates of 10-mm thickness are butt-joined by fusion welding.

Make sketches to show the expected weld bead geometry (in cross section) and the width of the HAZ with:

a) Oxyacetylene, 
b) Electron beam 
c) Shielded metal arc 
d) Plasma arc welding

Question 2:

Draw a sketch to show the basic design for preparing the edges of two 20-mm thick plates to be butt-joined by shielded metal arc welding with:

a) One sided access 
b) Two sided access 
c) Which of the two will be (relatively) free of distortion?

Question 3:

Given: Your company produces copper-clad steel sheet by hot roll bonding. A customer complains that the cladding separated during deep drawing.

Question: You are asked to investigate your company's procedure to make the sheet and identify possible problems. List the likely process steps and problem areas. 

Question 4:

Given: It is claimed that elevated temperature is essential for creating a metallic bond in rolling a sandwich of base metal plate and two cover plates.

Question: Do you agree? Justify. 

Question 5:

Given: A good weld of two 20-mm-thick steel plates is made by gas metal-arc welding .

Question: a) make a sketch of the weld bead b) suggest inspection methods for ascertaining quality of the weld.

Question 6:

Given: Many bicycle frames are constructed of steel tubing joined to hollow fittings.

Find:

a) Suggest a way of joining the tubes.

b) Define the process

c) Make a sketch of a joint and indicate critical features.
