Answer 4

tungesten inert gas: operator uses two hands one for filler material and one for the electrode. the tungesten rod is not disposable

Question 5

applications of TIG?

Answer 5

• bikes
• aerospace
• tubes

Question 6

arc welding MIG?

Answer 6

metal inert gas: operator uses 1 hand and the rod is disposable and it acts as the filler material

Question 7

applications of MIG?

Answer 7

railways

Question 8

Oxyacetylene Welding?

Answer 8

Fusion-welding processes use heat to melt the base metals. In many fusion welding operations, a filler metal is added to the molten pool to facilitate the process and provide bulk and strength to the 2 welded joint.

Question 9

flame cutting?
