Everyone is a high-level welding technician (3)

• The position of welding in modern heavy industry is unquestionable, and the quality of welding has become an important indicator of the level of manufacturing in heavy industry.

• The industry agrees that solder defects and solder baths have an important relationship. Whether or not to maintain a good molten pool state is an important indicator of the level of welding; on the other hand, the arc of welding is at the formation and end of the molten pool, and is also the two periods with the highest probability of occurrence of welding defects.

• Common welding masks have the following drawbacks

• Disadvantages 1:

• Using ordinary black glass pieces, the operator only grasps the position of the arc starting by the hand feeling, thus reducing the welding quality and inevitably causing material waste and high repair rate, which seriously affects the production efficiency.

• In some operations, it will cause open-eye welding at the moment of arcing, which may easily cause visual fatigue and electro-optic ophthalmia.

• Disadvantages 2.

• The black glass lens used in the common mask absorbs the infrared/ultraviolet filtering in an absorption manner, inevitably forms secondary radiation, etc., thereby causing visual fatigue caused by visual nerve damage, etc., which greatly affects the pair. Observation control of the weld pool and formation of good welds,

• Disadvantages 3:

• The traditional darkness of the protective mask is limited, which does not provide the operator's best observation darkness, which also affects the operator's observation of the weld pool, thus affecting the level of the welding practitioner in many ways, and As a result, various defects such as slag inclusion, undercut, stomata, incomplete penetration and welding cracks are caused, which results in high welding defects, and also causes welding quality and welding productivity to falter;

• Xun An automatic mask:

• Using spectral technology to permanently isolate UV/IR, etc.

• Using the latest LCD light control technology to achieve dark state transition within 0.1ms, the window darkness can be freely adjusted according to the intensity of the arc and personal habits, and greatly improve the welding practitioner while creating comfortable working conditions. The potential and skills (this has been fully verified in Europe and the United States).
