1.	Which of the following is not correct about submerged arc welding?(a) high deposition rate(b) short set-up time(c) high quality welds(d) slag removal neededI had been asked this question in an online interview.This interesting question is from Welding Process topic in portion Welded Connections of Design of Steel Structures
Answer» Correct option is (b) short set-up time For explanation I WOULD say: The following are some ADVANTAGES of submerged arc welding: (i) high deposition rate, (II)high QUALITY welds with good ductility, high impact strength, good corrosion resistance, (iii)good for welding long joints(in excess of 1m), (iv)no eye protection required. Some disadvantages are : (i) long set-up time, (ii)slag removal NEEDED, (iii)used for flat or horizontal fillets only.
