Use of base metals with fine grain structure OI, II, and III II, and IV OII, IV, and V O II, III and IV9) State true or false "Electro-slag welding offers better weld properties of medium carbon steel plate weld joints as compared to electro-gas welding in terms of grain structure" True FalseAnswer by true (T) or false (F) for the folling sentences 1. Fusion welding means that the two surfaces to be joined and the filler metal are meling during welding and then solidifying in similar menner to local casting process. 2. In oxyacetylene welding process, the welding is done using oxidizing flame only. 3. Explusive welding process produces strong joints of dissimilar materials that are not weldable by are. 4. Hot working leads to eliminating the porosity in the metal and increasing the strength and hardness. 5. Work hardening is a characteristic induced in the processing part because of the heat treatment.

- 2.8 Advantages of Submerged Arc Welding Cost per unit length of joint is relatively low The arc is under a blanket of flux, which virtually eliminates arc flash, spatter, and fume. • Extremely high deposition rates and welding speeds are possible. • Sound welds are readily made (with good process design and control). High current densities increase weld penetration and decrease the need for edge preparation. High speed welding of thin sheet steels at over 2.5 m/min is possible. Can be easily Automated Minimum welder training is required (relatively unskilled welders can be employed). • Low hydrogen weld deposits can be produced. • The flux acts as a scavenger and deoxidizer to remove contaminants such as oxygen, nitrogen, and sulphur from the molten weld pool. This helps to produce sound welds with excellent mechanical properties. 26 2.9 Limitations of Submerged Arc Welding Initial cost of wire feeder, power supply, controls, and flux-handling equipment is high. Limited to ferrous…Pipe-it Inc. wishes to modernize its facilities which refurbish used pipeline equipment. Robotic machinery appears to be the best option for the spot-welding process?QUESTION 3 Welding is a material joining process in which two or more parts are fused at their contacting surfaces by a suitable heat and/or pressure application.
