2. How to adjust the gas flow rate for secondary welding

1. Check if all connections are correct. After the water, electricity, and gas connections are completed, turn on the power and adjust the welding specifications parameters. The measured medium mass discharged by the micro flowmeter per revolution is four times the half moon product, and the volumetric flow rate through the micro elliptical flowmeter is Q.

2. Arc ignition. CO2 gas shielded welding adopts collision arc ignition to ensure the distance between the welding gun and the working distance. Before starting the arc, press the jog switch on the remote control box or the control switch on the welding gun to send the welding wire out of the nozzle, keeping the extension length 10-15mm. Place the welding gun at the starting point as required, and the end of the welding wire is not in contact with the workpiece. The height of the nozzle is determined by the welding current.

3、 The measuring part of the elliptical gear flowmeter is mainly composed of two interlocking elliptical gears and their housings. The elliptical gears generate a torque under the pressure difference of the measured medium, causing them to rotate. The gears alternate with each other to drive the other to rotate, and the measured medium is discharged from the inlet to the outlet one by one in half moon volume units.

3. What is the law of conservation of weight and flow rate? As we have experienced in daily life, liquids are inseparable. If you cut a knife into water, it may be cut off. This shows that fluids have continuity and cannot be separated. So when fluid flows through pipes with different cross-sectional areas, the flow rate must also be equal, that is, mass conservation. If derived from the formula, it is Q1=Q2, where density multiplied by velocity multiplied by cross-sectional area equals flow rate. Assuming the fluid is incompressible and the density remains constant, it can be ignored. Final: V1S1=V2S2. The law of conservation refers to the law in nature that the value of a certain physical quantity remains constant. The law of conservation of mass is defined that before and after a chemical reaction, the total mass of the substances participating in the reaction is equal to the total mass of the substances generated after the reaction. This is called the Law of Conservation of Mass. The process of chemical reaction is the process in which the molecules of various substances (reactants) participating in the reaction break and recombine into new molecules to generate other substances. In chemical reactions, the types of atoms before and after the reaction do not change, the number does not increase or decrease, and the mass of atoms does not change. In any isolated system, regardless of any changes or processes that occur, its total mass remains constant. Or in other words, any changes, including chemical and nuclear reactions, cannot eliminate matter, but only alter its original form or structure. Therefore, this law is also known as the law of non extinction of matter. Conservation of mass is one of the fundamental laws of nature. In any isolated material system (isolated system) that is isolated from the surrounding area, regardless of any changes or processes that occur, its total mass remains constant, energy is conserved, and the changes in energy in terms of quantity follow the most univer
