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.
Calculate the heat input during the arc welding process, if the voltage is 28 volts, current is 114 amperes, the length of the weld is 76mm and the time to complete the weld 30 secs. (Write the answers with two decimal places for eg. 1450.23) Speed S= One possible correct answer is: Heat Input (Watts)3D One possible correct answo
4. Design a welded connection to resist the loading shown below (service load). A double angle tension member, 2 L5x5x5/16, is connected to a 3/8 inch thick gusset plate with fillet welding. Fy = 50 ksi for the angles and Fy = 36 ksi for the gusset plate. Compute the size and length of welding on the side of angles based on LRFD and indicate the information on the sketch. 1 = %" 2L5 x 5 x h6 D = 30 k L= 75 k
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…
QUESTION 1 In an arc welding operation, a groove weld has a cross-sectional area=0.055 in² and is 24 in long. (Round your final answers to 1 decimal place) (a) What quantity of heat (in Btu) is required to accomplish the weld, if the metal to be welded is aluminum? Btu (b) How much heat must be generated at the welding source, if the heat transfer factor = 90% and the melting factor = 60%? H= Btu
The welding parameters to be used to butt weld a metal alloy are being evaluated. In order to set up the welding machine, the melting factor for the metal (f2) has to be determined. The welding machine can deliver 4000 watts of power and the heat transfer factor for the welding process (f1) is 0.9. The final weld bead consists of 8 0% filler metal and 40% parent metal. The melting temperature of the filler metal and the parent metal is the same 2540 deg F. The cross-sectional area of the weld bead is 0.5 sq inches. The rate at which filler metal is added to the weld is 1 cu inch per min. Conversion factor 1 Btu = 1055 J and 0 deg F = 460 deg R Calculate the melting factor.
3.) How many different types of welds are specified on the print and what are they? (Hint: look at the symbol on the reference line) 4.)For the weld between parts TP1 and TP2, what does the 3 mean? 5.)What standard should be used to interpret the weld symbols on this print? (Hint look at the notes given at the top of the print.) 6.) As indicated by the welding symbols, the welds to be made on ______________________?* a. the near side b. the far side c. both sides d. all around 7.)What note is found in the tail of the welding symbol? 8.)What is the name of this part? 9.)Who drew this print? 10.)What company was this print written for?
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 is

Q1: Explain what do we mean by rectifier? How it works, what type of welding machines have a rectifier in their components?
Q1) Prepare cross-sectional views of the following fillet weld and redraw the joints representing the weld using welding symbols: A lap joint of two (8 mm) plates forming a weld of concave face and leg size (8 mm). ii) i) A corner joint of (6mm) plate, forming a weld of convex face and leg size (6 mm). iii) T-joint of ( 8 mm ) plates with weld on both sides
