Abstract: A method of soldering a metal tubular element having an arcuate portion and an end portion to a metal female element receiving the end portion and defining a distal annular solder space. The elements are mechanically secured together and immersed in a solder bath with the solder space opening downwardly and with the arcuate portion of the tubular element lowermost. The elements may be preheated for improved solder coating thereof in the bath. The solder coated elements are withdrawn from the bath and immediately inverted to allow the melted solder thereon to run toward the end portion and into the solder space to prevent formation of icicles on the arcuate portion and provide an improved soldered connection to the female element.

Abstract translation: 将具有弓形部分和端部的金属管状元件焊接到容纳端部并限定远端环形焊料空间的金属阴元件的方法。 将元件机械地固定在一起并浸入焊料槽中，焊料空间向下开口并且管状元件的弧形部分最下部。 可以将元件预热以改善浴中的焊料涂层。 焊料涂覆的元件从浴中取出并立即倒置，以使其上的熔融焊料朝向端部部分延伸到焊料空间中，以防止在圆弧部分上形成冰柱，并提供与母体元件的改进的焊接连接。
