The invention relates to the technical field of condenser collecting pipes and particularly relates to an argon-free welding assembly method for a collecting pipe assembly. The collecting pipe assembly comprises collecting pipes and connecting pieces, wherein the collecting pipes and the connecting pieces are connected through fixing pins. The assembling method comprises steps that (1) the collecting pipes and the connecting pieces to be assembled are taken, and connecting holes are punched in the corresponding positions of binding faces of the collecting pipes and the connecting pieces; (2) the connecting pieces are fixed on an outer peripheral surface of the collecting pipes; and (3) after the collecting pipes are connected with the connecting pieces, brazing along contact edges of the connecting pieces and outer peripheral surfaces of the collecting pipes is performed. The welding assembly method is advantaged in that argon welding is not used in the whole process, the risk that thecollecting pipes are prone to breakdown in the argon welding process, and consequently slow leakage occurs in the follow-up using process of the collecting pipes is avoided, the assembling percent ofpass is increased, moreover, argon welding is not adopted, the welding frequency is reduced, harm of argon to the human body is reduced, assembling efficiency is improved, and assembling cost is reduced.
本发明涉及冷凝器集流管技术领域,尤其是一种集流管组件免氩焊装配方法;集流管组件包括集流管和连接件,集流管与连接件之间通过固定销连接,装配方法包括以下步骤:(1)取待组装的集流管和连接件,在集流管和连接件贴合面的对应位置冲连接孔;(2)将连接件固定在集流管外周面上,(3)集流管与连接件连接后,沿连接件与集流管外周面的接触边缘进行钎焊;本发明中的焊接装配方法,整个过程未使用氩焊,避免了氩焊过程中容易击穿集流管,造成集流管后续使用过程中发生慢泄漏的风险,提高了装配合格率,同时,由于未采用氩焊,减少了焊接次数,减少了氩气对人体的伤害,提高了装配效率,降低了装配成本。
