一种焊接方法
摘要：
本发明涉及一种焊接方法，包括以下步骤：将第一焊件的焊接端与第二焊件的焊接端搭接；在第一焊件的焊接端与第二焊件的焊接端之间放置密封剂；从第一焊件或/和第二焊件的外侧，对第一焊件的焊接端与第二焊件的焊接端进行搅拌摩擦焊接；焊接过程中产生的热量将密封剂溶化，被溶化的密封剂将第一焊件的焊接端与第二焊件的焊接端润湿，并与第一焊件的焊接端与第二焊件的焊接端相互溶解，用以填充第一焊件的焊接端与第二焊件的焊接端的焊接间隙。本发明的有益效果为：在焊接的过程中通过密封剂填充焊接界面，提高了焊接接头的抗腐蚀性能和力学性能。
摘要（英）：

The invention relates to a welding method. The welding method comprises steps as follows: a welding end of a first weldment is lapped at a welding end of a second weldment; a sealant is placed between the welding end of the first weldment and the welding end of the second weldment; stirring friction welding is performed on the welding end of the first weldment and the welding end of the second weldment from the outer side of first weldment and/or the second weldment; the sealant is molten by heat produced during welding, and the molten sealant wets the welding end of the first weldment and the welding end of the second weldment and is dissolved with the welding end of the first weldment and the welding end of the second weldment to fill a welding gap between the welding end of the first weldment and the welding end of the second weldment. The welding method has the benefits as follows: a welding interface is filled with the sealant during welding, and the corrosion resistance and the mechanical property of a welding joint are improved.
