一、概述我厂试制的硅铝电焊条及其涂药配方,具有良好的脱氧脱氢的能力和较好的抗裂性能,可以打破焊前要求予热到200℃～300℃的常规。缺陷表面不要求用化学方法清除氧化铝膜的工序,只要没有油、脏物就可直接焊补,象焊接低碳钢那样容易。焊接金属与母材溶合和成型情况良好,表面光泽、美观,且能呈现鱼麟状.焊接时飞溅较小,熔 First, an overview of our plant trial production of silicon aluminum welding rod and its coating formulations, has a good ability of dehydroxy dehydrogenation and better crack resistance, you can break the pre-welding requirements to heat to 200 ℃ ~ 300 ℃ conventional. Defective surfaces do not require chemical removal of the alumina membrane process, as long as there is no oil, dirt can be directly welded, as easy to weld low-carbon steel. Weld metal and base metal fusion and molding in good condition, the surface gloss, beautiful, and can show Yulin-like. Welding spatter smaller, melting
