Information

The material making of welding elbow pipe fittings is a new type of material with special electric, magnetic, mechanical, chemical and biological functions, which plays an important role in the high-tech field of biotechnology, information technology, power technology and important basic materials for national defense construction, such as agriculture, chemical industry and building materials. At high temperature, the weld metal absorbs too much gas (such as H2) or the gas generated by the metallurgical reaction inside the bath (such as CO), which is too late to be discharged when the bath is cooled and solidified, and holes are formed inside or on the surface of the weld, that is, pores. The existence of pores reduces the effective working section of the weld and reduces the mechanical strength of the joint.

After the welding construction operation is completed, it is necessary to carry out anti-rust or anti-corrosion treatment according to the actual situation or the external environment of the pipeline, so as to prevent the elbow pipe from rusting or corrosion at the weld, and the service life of the elbow pipe is too short. Before welding elbow pipe fittings, in order to prevent welding deformation, the two sides of the whole elbow fittings are strengthened with stainless steel arc plate and keel. During welding, two welders, inside and outside, are used to weld symmetrically, which not only handles the argon filling problem well, but also has a good shape.
