The methods of welding red copper (that is, the so-called industrial pure copper) include gas welding, manual carbon arc welding, manual arc welding and manual argon arc welding, and automatic welding can also be used for large structures. 1. Gas welding of copperButt joints are the most commonly us
Submersion test For small containers or pipes with low internal pressure. Fill the container or pipeline with compressed air with a certain pressure (0.4-0.5MPa) before inspection. Then submerge in water to check the tightness, such as right leakage; bubbles must occur in the water. This is also a c
The answer to this is a resounding no. The tungsten will disintegrate with out any shield gas. There will be no welding happening period. I read the other guys answer and it's so far out to lunch it's a joke. First off its spelled porosity not perosity and this other bullshit about by the the other
To strike the welding arc, a high frequency generator (similar to a Tesla coil) provides an electric spark. This spark is a conductive path for the welding current through the shielding gas and allows the arc to be initiated while the electrode and the work piece are separated, typically about 1.5–3
The TIG welding process enables you to obtain very high quality welding especially for demanding sectors of application, such as pressure vessels, pipelines, food industry containers and aviation.
There are many types of TIG torches for different welding applications. TIG torch sizes vary greatly for different jobs. This article will help break down the basics for you when it comes to selecting your first torch. Depending on your amperage needs and your budget, there are always several good t
Pneumoconiosis is an IRREVERSIBLE industrial disease，and leading to DISABILITY. The average time from onset to death is only 3 ~ 5 years .Among all the industrial diseases, pneumoconiosis accounted for over 90%, and the mortality rate was as high as 22%！The incidence of welder pneumoconiosis is clos
Whats is the best MIG WELDING TORCHES AND GUNS?Ever since MIG welding was invented, it has become one of the most prioritized welding methods for various applications. As MIG welding is faster than any alternative option and also a lot less messy, it is the first choice for many welders for multiple
