The paper can pass the duplicate check, be fluent in arts and sciences, stay on topic, and be qualified.
In fact, as long as you write your paper carefully, there will be no problem.
A university teacher believes in Buddhism, and students ask their tutor how to write their graduation thesis, which is an answer sheet reflecting their personal knowledge. This has nothing to do with the teacher's beliefs.
The teacher sends a text message to tell you how to reply. Thank you, I see. I'm sorry to bother you in your busy schedule!
How to write a graduation thesis as a welding teacher? Duplex stainless steel welding process Duplex stainless steel welding process, using 99.99% argon inert gas protection, manual argon tungsten arc welding backing welding; Using 80% argon and 20% carbon dioxide gas protection, semi-automatic filling cover welding was carried out. When duplex stainless steel is welded, the metallographic structure with relatively balanced ferrite and austenite ratio can be obtained, and the ferrite content is about 45-65% by determination. The mechanical properties and corrosion resistance of the welded joint are fully guaranteed, and its tensile strength is about 640 N/mm2, and its hardness is between 220-280HV 10. Using carbon dioxide+nitrogen mixed gas as shielding gas can reduce welding spatter and make the weld shape beautiful. Welding technology of duplex stainless steel, including backing and filling cover welding. (1) manual TIG backing weld with 99.99% argon inert gas includes the following process steps: a. Panasonic TSP-300 manual /TIG welder is selected as the power supply, the polarity of the power supply is DC connection, the protective gas of the molten pool is 99.99% argon, and the flow rate is10-8 liters. The welding wires for argon arc welding are Lincoln lnt 4462φ2.0, AWSA 5.9: ER 2209, tungsten thorium tungsten φ 2.4, ANSI/AWA5.12-92. The welding position is fixed horizontally, the wall thickness is 8- 10 mm, and the joint form is butt V-joint, and the groove angle is 60 5. B, horizontally fixing the assembled workpiece on a welding frame, sealing the nozzle with only an air inlet and an air outlet, and introducing argon as a back protective gas for 3-5 minutes, wherein the gas flow rate is 5-10l/min; C, a licensed welder carries out backing weld, the current is 70-90 amps, the voltage is11-13v, the welding speed is 30-50mm/min, and protective gas is continuously introduced; D, after the whole welding is completed, the second layer of hot welding is carried out, the current is 105- 150A, the voltage is 13- 18V, the welding speed is 75- 130mm/min, and the flow rate of shielding gas in the molten pool is/kloc. E, after the second layer of welding, continue to transfer the protective gas backwards. (2)80% argon and 20% carbon dioxide gas shielded semi-automatic welding includes the following process steps: a. The selected power supply is Panasonic KRII-350 carbon dioxide welding machine, and the polarity of the power supply is DC reverse connection, the protective gas of the molten pool is 80% argon and 20% carbon dioxide, the back protective gas is 99.99% argon, and the flux-cored wire is Lincoln COR-A-ROSTAP4462φ. B, measuring the weld temperature after hot welding with liner, and keeping the interlayer temperature ≤150℃; C, the welder with certificate shall carry out filling welding with current 140- 180A, voltage 23-29V, welding speed 140-2 10 mm/min, and shielding gas flow in the molten pool 15-20L/min. D, welding the cover surface after filling welding, wherein the current is 130- 160A, the voltage is 23-27V, the welding speed is 170-230mm/min, the flow rate of shielding gas in the molten pool is 15-20L/min, and the interlayer temperature is controlled.
I failed my graduation thesis. I'm afraid the teacher will scold me. Don't be afraid to face failure, stand up and start over.
The specific function of the graduation thesis tutor is to help you revise your thesis to meet the requirements of the school and help you pass the exam in time, because the tutor is very experienced in this field.

I think teachers should be our friends.
The teacher should not be so strict with us.
4. The course should be more vivid.
I think teachers should organize these activities more carefully.
How to politely refuse the teacher's suggestion to buy a guitar in his musical instrument store? Our guitar teacher successfully tricked me into buying a 5000 piano for 7000 yuan.
Should teachers be invited to dinner when writing graduation thesis in universities? In addition, the tutor takes the students to write their graduation thesis. Does the school give money to the tutor? I graduated, left school, and had nothing to do with my tutor. Did some teachers invite him to dinner and then hide? These activities are voluntary.
