Beschreibung
Zusammenfassung:	The invention relates to a seamless rack rail and a welding method thereof.The method comprises the steps that a first rack and a second rack which are adjacent to each other are fixed, and a filling space is formed between the opposite ends of the first rack and the second rack; and the filler space is filled with a welding material for welding, and the melting point of the welding material is lower than that of the first rack and that of the second rack. According to the welding method of the seamless rack rail, the melting point of the welding material is lower than that of the first rack and that of the second rack, the influence on the physical and chemical properties of rack base metal is small, the welding stress and deformation are small, welding allowance does not need to be reserved when the racks are manufactured, the racks do not need to be moved in the welding process, and the welding efficiency is improved. And it can be guaranteed that the tooth pitch is kept unchanged after the seamless rack r
