摘要:河南不锈钢浮雕,不锈钢焊条在使用时应保持干燥。为防止产生裂纹、凹坑、气孔等缺陷,钛钙型药皮焊前经150-250℃烘干1h,低氢型药皮焊前经200-300℃烘干1h。不能多次重复烘干,否则药皮易脱落。

 

    河南不锈钢浮雕,不锈钢焊条在使用时应保持干燥。为防止产生裂纹、凹坑、气孔等缺陷,钛钙型药皮焊前经150-250℃烘干1h,低氢型药皮焊前经200-300℃烘干1h。不能多次重复烘干,否则药皮易脱落。


    Stainless steel stainless steel in Henan, stainless steel electrode should be kept dry when used. In order to prevent the crack, pit, porosity, titanium calcium based skin welding before drying 150-250, low hydrogen type of medicine before the 1H drying 200-300 for 1H. Can not repeat the drying repeatedly, otherwise the skin easily fall off.


    焊口清理干净,同时防止焊条沾上油及其它脏物,以免增加焊缝含碳量并影响焊接质量。


    The weld is clean, while preventing the electrode coated with oil and other dirt, to avoid increasing the carbon content of the weld and welding quality.


    河南不锈钢浮雕,引弧时注意,不能在非焊接部位引弧,最好选用与焊件相同材料的引弧板来引弧。


    Henan stainless steel relief, drawing attention, can not lead in the non welding parts of the arc, the best selection and welding parts of the same material cited arc.


    应尽量采用短弧焊接,弧长一般2-3mm,电弧过长易产生热裂纹。运条:应采用短弧快速焊,一般不允许横向摆动,其目的是减少热量和热影响区宽度,提高焊缝抗晶间腐蚀能力和减少热裂纹的倾向。


    The arc length is generally 2-3mm and the arc is too long to produce hot cracks.. The short arc welding should be used, generally not allow the horizontal swing, the purpose is to reduce the heat and heat affected zone width, improve the weld resist intergranular corrosion ability and reduce the tendency of hot cracking.


    不锈钢浮雕,为防止加热而产生晶间腐蚀,焊接电流不宜过大,一般应比碳钢焊条低20%左右,电弧不要过长,层间快冷,以窄道焊为宜。


    Stainless steel relief, to prevent heat generated intergranular corrosion, welding current should not be too large should generally be ratio of about 20% of low carbon steel electrode and arc not too long, interlayer fast cooling, with narrow welding is appropriate.


    以上是金兰草浮雕为你提供的不锈钢浮雕焊接步骤和方法。


    The above is to provide you with the grass Jinlan embossed stainless steel welding procedure and method of relief.
