1、 What is precision level?Accuracy level is an indicator that measures the maximum allowable error between the measured value and the true value of a pressure gauge. It is usually represented by a number, the smaller the number, the higher the accuracy, the smaller the allowable error range, and the higher the manufacturing cost.2、 The […]

Argon is one of the most widely used shielding gases in welding because it is an inert gas that can effectively protect the molten pool from air pollution.Simply put, the vast majority of common metals and alloys can be welded using argon gas, especially the TIG welding method.Below, we will provide a detailed explanation by
Which metal materials can be welded with argon gas? Read More »
In welding, we usually do not directly set and monitor the pressure of CO ₂, but focus more on and control the flow rate.This is because the pressure during transportation will vary due to the length of the pipeline and the number of joints, while the flow rate directly determines whether the amount of gas

Choosing an argon pressure reducer for welding is a very practical issue. argon gas is an inert gas that is always in a gaseous state, making it easier to choose, but there are still key points to note. Single gauge pressure regulator (only with output pressure/flow meter)1. Characteristics: There is only one meter head, usually

The choice of CO ₂ pressure reducer for welding (more accurately referred to as CO ₂ arc+CO ₂ pressure reducer) is very important, as it directly affects the stability of gas output and welding quality. The following are the key points for selection, you can refer to this process to choose: 1、 Firstly, confirm the

In oilfields, particularly during the exploration, development, and production of oil and gas fields, a wide variety of pressure gauges are used. Depending on different working conditions, measurement media, and accuracy requirements, various types of pressure gauges are selected. 1、 Classified by working principle and display modeThis is the most basic classification method.1）Pointer type (mechanical)

The selection of pressure gauge housing is a very practical and important issue. The shell case is the “first line of defense” of a pressure gauge, which not only affects its appearance, but also directly affects the protection level, durability, applicable environment, and safety of the pressure gauge.
