1.	Choose the correct option regarding metal-active gas welding?(a) not suitable for thin metal sheets(b) need to stop welding to change the consumed electrode(c) equipment is not expensive(d) high deposition rateI got this question by my college professor while I was bunking the class.My doubt stems from Welding Process topic in division Welded Connections of Design of Steel Structures
Answer» The correct answer is (d) high deposition rate Explanation: GAS-shielded metal arc welding is ALSO called metal-active gas welding. The following are some advantages of gas-shielded metal arc welding : (i) suitable for metals as thin as 0.58mm, (ii)all welding positions can be used, (III) no need to stop welding to change the consumed electrode, (iv)high deposition rates. Some disadvantages are : (i)welding equipment is expensive and COMPLICATED, (ii)cannot be performed outdoors in greater than 8km/hr BREEZE.
