- Answer 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.During a TIG welding process, the arc current and arc voltage were 50 A and 60 V, respectively, when in the welding speed was 150 mm/min. In another process, the TIG welding is carried out at a welding speed of 120 mm/min at the same arc voltage and heat input to the material so that weld quality remains the same. The welding current (in A) for this process isA welding fabricator welds mild steel attachments to AISI 304 stainless steel shells, using GTAW with ER309L filler wire. A helium-based shielding gas (90% He-7.5%Ar-2.5%CO2) is used, but the high cost of this shielding gas is becoming an obstacle. To reduce costs,
- (b) Illustrate the schematic diagram of shielded metal-arc welding process.In one type of welding, electric charge flows between the welding tool and the metal pieces that are to be joined. This produces a glowing arc whose high temperature fuses the pieces together. Why must the tool be held close to the metal pieces? (i) To maximize the potential difference between tool and pieces; (ii) to minimize this potential difference; (iii) to maximize the electric field between tool and pieces; (iv) to minimize this electric field; (v) more than one of these.Arc welding is an example of pressure welding. Select one: True False
