You have this additional information: P-GMAW Productivity is substantially lower. However, you have welders already qualified to do manual p-GMAW welding. Labor is 80% of total cost HYPERFILLⓇ® Productivity gains are important, and the volume of the product is sufficient on the rail tank cars to justify capital investment. With confidence, you respond: Use process because .(Give process and short explanation for why you want to use that process)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.
