Basic Knowledge of Sheet Metal Processing
We will introduce the basic knowledge of sheet metal processing.
"Welding processing" refers to the process of joining two or more metal parts together. This page introduces "CO2 welding" and "TIG welding," which are methods of welding implemented at Tsubota Technica. - CO2 Welding In arc welding, gas (shielding gas) is used to maintain the quality of the joint while stabilizing the arc. CO2 welding uses CO2 as this shielding gas. It results in deep penetration and strong fusion between the base materials. It is a semi-automatic welding process. It tends to produce spatter, which is welding debris (metal droplets that solidify when scattered during welding), and the appearance after welding can often be messy. The spatter needs to be ground off to clean it up. - TIG Welding This is an arc welding process that uses tungsten alloy for the welding electrode and argon as the shielding gas. The weld bead is beautiful, and it allows for welding of aluminum, which is not possible with CO2 welding. It is also suitable for welding other non-ferrous metals. Since it is not a semi-automatic process, both hands must be used during welding, requiring a certain level of skill. The gas is relatively expensive, resulting in higher costs compared to CO2 welding. Other welding methods will be introduced from section (4) onward.
