Tip：The role of argon flow rate
If the argon gas is too small, the protection effect is poor, and the metal to be welded will be severely oxidized.
If the argon gas is too large, turbulence will be generated due to the large air flow, causing the air to be drawn into the molten pool by the turbulent gas, resulting in poor protection of the molten pool and oxidation of the weld metal.
Therefore, the flow rate must be determined according to the plate thickness, current size, weld position, and joint type. The specific decision is based on the weld protection effect, and the standard is that the metal being welded does not oxidize.
