Tip：What are the factors that affect the gas protection effect of argon tungsten arc welding?
The factors that may affect the gas protection effect of argon tungsten arc welding are as follows:
① The protection gas flow is not suitable too large or too small will make the protection effect worse.
(2) Side wind side wind interferes with the protective gas layer, if the wind speed is small, it can be eliminated by appropriately increasing the protective gas flow; If the wind speed is high, measures must be taken against the wind.
(3) The welding speed is too large, the welding speed increases, the air resistance encountered by the protective air flow increases, the protective air flow lags behind the nozzle, and the protection effect of the front of the molten pool will become worse
The welding of the butt joint and the inner fillet weld is easy to achieve good protection, and the air is easily involved when the outer fillet weld and the end weld are welded, so the baffle should be used to block
In addition, the size of the nozzle and the distance from the nozzle to the workpiece also affect the gas protection effect.
