Nama : I Kadek Dwi Putra Prasetya ( 1815213041 ) I Kadek Dalem Billy Rahmadika (1815213061 ) Kelas : III A T.M Conversation About OAW and SMAW Welding Billy : Hello Good morning Dwi Dwi : Good morning to Bil Billy : How are you ? Dwi : I’m fine and you ? Billy : Fine, dwi. Did you practice OAW welding yesterday ? Because i didn’t come in yesterday Dwi : yes i already got practice yesterday Billy : Can you tell me about OAW welding ? Dwi : Sure, OAW welding Or oxy – acetylene welding is a gas welding process that uses a heat source of flame throught combustion of oxygen gas and acetylene gas to melt the metal and filler Billy : Ohh, that’s the definiton of OAW welding, what about OAW welding tools? Dwi : Oxygen tube, acetylene tube, Oxygen regulator, acetylene regulator, gas hose, welding torch, welding nozzel, welding rod or filler, brander cleaning Billy : What is the temperature of the flame produced to melt the metal and filler? Dwi : The temparature is 3500 celcius degrees to melt metal and filler Billy : Ohh, thanks for your information Dwi Dwi : Bill, can you tell me about SMAW welding ?, because i’m still confused by that Billy : Sure, SMAW welding or shielded metal arc welding is a welding process that use heat from electricity and electrode as filling material to melt the metal and become connected Dwi : Where is the heat energy produced by welding machine? Billy : The heat energy in the SMAW welding process is a generated from the jump of ions ( cathodes and anodes ) electricity that occurs at the tip the material of metal Dwi : what is the temperature of electric ion jump from SMAW welding ? Billy : the temperature is 4000 until 4500 celcius degrees Dwi : what is the SMAW welding tools? Billy : transformer, mass cable and electrode cable, holder/electrode holder, mass clamps, source cable, on or holder button, ampere regulator and the support tools same like OAW welding that is slag hammer, steel wire brush, pliers Dwi : ohh thanks for your information about SMAW welding bill Billy : you are welcome dwi, let’s practice welding in the mechanical laboratory dwi Dwi : yes let’s go.
