Welding experience

I never do any welding before yet i have to try doing it. Kinda scary to see the sparks coming out from the electrodes and the red heat huh.. my first welding method is the arc which demands high skills and consistency. Plus need to be patient because sometime the elelectrode can stuck onto the plate and kinda hard to repel it from the plate. Wearing the mask also cool. I can't see a thing except the uv light heat at the tip of the electrode. In that method, i learned on how to weld free runs and paku kimpal... kinda cool. Have two options whether to use half circle or full circle. I used the full circle as it is much easier.

Next, the Gas. First, the technician explains bla bla. And demonstrate on how to get the best neutral flame for gas welding. The gas welding uses two gases which are acetylene and oxygen. At first, we have to release a bit or acetylene and put a spark at the nozzle at boomf.. the flame .. yellowish flame. The technician said to differentiate the two gases is the acetylene smells bad and oxygen no smell. Then, after getting a nice flame, i do my welding. Kinda easier than arc method. My product kinda nice.

Next the MIG. The briefing bla bla.. the mig uses CO2 to push the electrode out. Easiest among all methods. I learned on how to weld tee joints and free runs. And my product kinda nice. I helped my friends sometimes in welding. And this is the last method i learned about welding. After this i'll learned the gegas and fabrikasi.

As conclusion, welding was scary at first, but when we get used to it, we'll become better. Safety measures need to be taken as we are dealing with hot materials. huh.. i think dats all.

  1. It's always the first time that's most difficult. Welding could be complicated for first timers, but a very handy skill to acquire. Careful practice, safe gear, and welding tools are so much needed for this task. Good thing you are being guided by a technician while going through it.
