The arc and weld pool are shielded by a stream of inert or active gas.
It provides an effective protection of the weld pool by an inert shielding gas.
A continuous electrode(the wire) is fed by powered feed rolls(wire feeder) into the weld pool.
The steel core melts into the weld pool and provides the necessary filler material.
When the coating is burning/melting it produces shielding gases andslag which protect the weld pool.
The dimensions of the weld pool is difficult to control, as by heating the aluminum virtually does not change its color.
This means that the gas is separated in the arc and to a smaller orlarger extent reacts with the weld pool.
The arc and the weld pool are protected by means of certain minerals that create gases and slag during welding. .
Defects in the form of burn-throughs appear as holes through which the melt has flowed from the weld pool.
The cathode spot on the surface of the weld pool during operation is subjected to constant exposure to a stream of aluminum ions.
Titanium is excellent for most grades butextra care have to be taken for the gas protection on the weld pool, the.
In the process of solidification andrapid cooling of the weld pool, hydrogen is too late to overflow and hydrogen holes are easily formed.
The liquid aluminum dissolves large quantities of hydrogen,which is difficult to removed by rapid solidification of the weld pool.
If the electrode is moved too quickly, the weld will be defective, since the weld pool line will lie deeper than the metal surface.
The weld pool is always protected by a shield of gas in order to protect both the melting wire and the weld pool from the oxygen and nitrogen in the air.
When connecting products using pulse technology,non-contact transfer of the electrode metal into the weld pool takes place.
It is necessary to raise the working tool from the weld pool, then go back along the seam a few millimeters back and only then quickly take it to the side.
This metal in the form of droplets fills the space between the melted edges of the workpiece in the weld pool- as a result, a weld is formed.
During the welding process the electrode,the arc and the weld pool are protected against the damaging effects of the atmospheric air by an inert shielding gas.
Such a defect is caused both by improper crystallization of the melt, and by exceeding the concentration of carbon,sulfur and phosphorus in the weld pool.
The coating produces shielding gases and slag during the welding which protect the arc and the weld pool, thus making it possible to produce welds unaffected by the harmful atmospheric air.
To prevent air pollution,the titanium weldment needs to be protected to 800 degrees Fahrenheit(427 degrees Celsius) and the weld pool.
Protective gas: Argon gas with a purity of 99.995% and a water content of less than 50 mg/m3 shall be used for argon gas protection in the weld pool and the area of the inner and outer surfaces of the welded joint above 400 °C.
When sealing defects at the edges of the product, or welding through cracks,it is better to use graphite molds that prevent liquid material from escaping from the weld pool.
By changing the basic parameters of the welding process,the operator can change the shape of the weld pool and its dimensions, control the crystallization process of the metal, form the weld, adjust the limits of deformation, etc.
Having received the necessary experience, the welder no longer pays attention to the position of the electrode during welding, his main focus is on what happens during welding in the weld pool.
Argon gas protection is applied to the area where the temperature of the inner andouter surfaces of the weld pool and weld joint is higher than 400°C.
This metal in the form of droplets fills the space between the melted edges of the workpiece in the weld pool- as a result, a weld is formed.
Main protection welding pool;
The aluminum welding pool is prone to shrinkage, shrinkage, hot cracking and high internal stress during solidification.
