Precision light pipe welded butt joints before welding primer tube and the cavity should be filled with argon gas to perform TIG welding. In certain particular at low temperatures, the operation of fingerprint adhesion ranking officials will also impact the workpiece. Do not make the workpiece gets new oil. Wear clean gloves must operate. If the surface of the lubricating oil during cold adhesion must trichlorethylene degreasing agents, caustic soda solution and then with warm water to fully defatted.
While affirming the load, the higher the temperature and the longer the time angry creep to occur the greater. Design units are also based on environmental conditions, corrosion and corrosion tape required product characteristics were selected. Precision light pipe according to different cross-sectional shapes can be divided into tube and shaped tubes. Therefore, the operator should not directly touch the fertilizer tube fittings, in affirming the special temperature at low temperatures, the greater the load seamless tube made of fire creep occurs faster; ring with a steel pipe manufacturing parts, can improve the material utilization, and simplify the manufacturing process, saving material and machining time, such as bearing rings, steel pipe and solid steel bar, etc. compared to the same torsional strength in bending, lighter, precision light pipe is an economic cross-section steel , widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding. Jack sets, has been widely used to make steel. Steel or a variety of conventional weapons indispensable material, barrel, barrel, etc. to make steel. Greater load creep occurs faster firing; under load in the affirmative, the higher the temperature and the longer the time angry creep can occur the greater.
