GAS WELDING Gas welding is a process that use fuel gases and oxygen to weld and cut metals. Uses: 1-welding and cutting metals 2-in Stone Work for flaming 3-in the glass industry for fire polishing 4-in jewelry production How we use it : The apparatus used in gas welding consists basically of an oxygen source and a fuel gas source it’s pumped through hoses and get out to cut or weld the used metal and there are two cylinders one of them contain oxygen and we can control

several procedures before tensile test been conducted. First of all‚ after finished with the welding and cutting process‚ the specimen was file using flat file in order to remove the burr. Then‚ the specimens’ thickness been measured by using the varnier calliper. Next‚ by using the surface grinding machine‚ the entire tensile specimen had been grind. This is to ensure the notch that appeared from welding process affected the specimens performance while tensile test. Again‚ after the grinding process

5.7 Necessity of D.C. Motor Starter At starting‚ when the motor is stationary‚ there is no back e.m.f. in the armature. Consequently‚ if the motor is directly switched on to the mains‚ the armature will draw a heavy current (Ia = V/Ra) because of small armature resistance. As an example‚ 5 H.P.‚ 220 V shunt motor has a full-load current of 20 A and an armature resistance of about 0.5 . If this motor is directly switched on to supply‚ it would take an armature current of 220/0.5 = 440 A which

The failure mode was determined from the failed samples. 2.3 Metallography The macroscopic examination also termed as macro test were used to assess the quality and consistency of a test samples representing the flow of material during the welding procedures. Macro tests were achieved at 10x magnifications.
