双控开关的接法

双控开关的接法 这种接线方式比较简单，是正规做法: 下面是双联开关的实物: 上图是双联开关实物图 25Cr-13Ni type or a welding material with high nickel content. Low temperature steels, austenitic stainless steel and heat-resistant corrosion-resistant high alloy steels and austenitic and non-austenite dissimilar steel welded joints shall comply with the following requirements: to ensure penetration and fusion under good conditions, low current, short-arc, welding speed and much faster welding process and interpass temperature should be controlled. High corrosion resistance performance of double-sided welded welds, welded layer in contact with corrosive media finally welded. Low temperature steel welding, suitable for the surface of the weld bead annealing. Check 6.6.1 6.6 welding inspection before welding material and welding materials, must be carried out according to standard acceptance, unqualified persons may be used. Group before the dimensions of various parts of the main structure, Groove sizes, and grooved surface for inspection. Welding Groove and Groove on both sides should be checked before the cleaning quality. Check the welding before welding conditions are consistent with the prescribed conditions, and welding equipment. The drying and cleaning of welding materials to confirm that it meets the requirements. 6.6.2 intermediate welding inspection tack welding after the skull should be cleared checks to welding the defects found shall be removed before they can. Multi-layer welding welding after the each floor should immediately clean the layers, and Visual inspection, found defects in welded to eliminate before they can proceed to the next level. To interrupt the welding seam, should be cleaned and checked before continuing to weld to eliminate welding defects found by the rear. 6.6.3 check after welding seams shall be welded ends immediately after the removal of slag skin, splash, clean weld and weld inspection. Profiles should shape forming beautiful, not undercut, cracked, incomplete fusion, blowhole, slag, splash and other defects. Weld reinforcement should 25Cr-13Ni type or a welding material with high nickel content.
