铸·焊·锻就是用铸造的方法将与焊件材质相同的液态金属注入两待焊接件所设定的密闭的焊缝(相当于型腔)中,由于焊件的焊接面涂有药皮(相当于焊条药皮),因此,就能像电弧焊一样使焊接件很好地焊接在一起。当焊缝处冷却至可锻(适用钢件)温度时,像摩擦焊一样,可通过外力或其自重对焊件或焊接头(适用焊接件不可移动)施以较大的顶锻力,以实现焊缝处锻造之目的。且焊缝处只有同时浇注、冷却才能实现锻的可行性。铸·焊·锻可克服传统的焊接方法中沿焊缝长度方向所产生的各种变形及残余应力,因此,铸·焊·锻这一工艺所焊接的焊接件保持了铸和锻的优点,克服了焊的缺点。
Casting · Welding · Forging is the method of casting the liquid metal with the same welding material into the two to be welded set in a sealed weld (equivalent to the cavity), the weld surface coated with a coating (Equivalent to the electrode coating), so it can be welded like arc welding the same good together. When the weld is cooled to malleable (applicable steel) temperature, like friction welding, the external force or its own weight on the weldment or welding head (applicable welding pieces can not be moved) to apply a greater upsetting force to To achieve the purpose of forging at the weld. And the weld at the same time only pouring, cooling can achieve the feasibility of forging. Casting, welding and forging can overcome various deformations and residual stresses in the traditional welding method along the length of the weld. Therefore, the welding parts welded by the process of casting, welding and forging maintain the advantages of casting and forging, Overcome the shortcomings of welding.
