How to improve the welding regulations of titanium alloy titanium pipe joints

Because titanium alloy titanium tube is more open-minded, and when performing the welding of titanium alloy titanium tube, there are stricter regulations on the control of welding temperature, the actual effect of maintaining the maintenance of the steam, and the natural environment of the welding. It will cause great harm to the welding quality and will cause damage to the product when it is more serious. Practical experience: According to the development of various key factors that endanger the quality of welding, clarify the important whole process of welding, improve the manipulation of the natural environment, staff, and main welding parameters and methods in the whole process of welding, so as to reasonably ensure the quality of titanium pipe raw materials. Welding quality has been further improved to avoid the appearance of welding waste.

In recent years, a new type of Ti 6Al-2Sn-4Zr-6Mo Titanium Rod alloy titanium pipe fittings has been widely used. Because aluminum alloy has the characteristics and characteristics of light ratio, high compressive strength, corrosion resistance, etc., in addition to being widely used in aerospace, petrochemical equipment, and mechanical equipment manufacturing industries, it is also used for the first time in the pipelines of river ships at this stage. Under construction. However, because the aluminum alloy is a kind of metal material with strong cheerfulness, it has great infectious power to vapors such as oxygen, hydrogen, nitrogen, etc. at high temperatures, that is, the ability to digest, absorb and melt vapors is very strong, especially when facing welding In the whole process, this kind of ability is mainly manifested especially as the welding temperature rises. Practical experience, if the digestion, absorption, and melting of aluminum alloy and oxygen, hydrogen, nitrogen, and other vapors are not controlled during welding, it will eventually cause damage to the product. Therefore, in the welding of ERTi-23 Titanium Welding Wire pipe joints, reasonable prevention and manipulation must be made in many aspects to consider the quality regulations on welding.

How to improve the welding regulations of titanium alloy titanium pipe joints

Welding workers should wear clean-up work clothes, and there must be no oil stains. Welding gloves should use white sand cloth gloves, and it is prohibited to wear cotton rope and gloves made of other materials.

The welding service platform section and the wire brushes used in the welding area of ​​the welded joints should be made of stainless steel plates. Carbon steel and other environmentally polluting materials are prohibited.

The welding place should be set as far as possible in the room or in the middle of special welding work. Smoking is prohibited in the room. The natural environment should be kept clean and dry. The indoor temperature should not be less than 5℃, and the heat convection of the gas should be strictly controlled.

In order to better obtain a more ideal welding quality, try to produce and process the butt joint top into a V-shaped weld, and use toluene for deoiling the welding area and the surface of the electrode.
