A welding device and method for brazing material, core tube and brazing material

Abstract

The invention discloses brazing filler metal as well as a welding device and method for a core tube and the brazing filler metal. The welding device comprises a rack, wherein a conveying mechanism forconveying the core tube is arranged on the rack; an accommodating part for accommodating the core tube is arranged on the conveying mechanism; wound brazing filler metal are separately placed at thetwo sides of the inlet of the conveying mechanism; welders are arranged at the two sides of a conveying line of the conveying mechanism; each brazing filler metal ring of the brazing filler metal is connected to one core tube; and in a forward conveying process of the core tube, the core tube can be automatically inserted into the hole wall of the brazing filler metal ring, and is fixed by welding. The invention further discloses the brazing filler metal and the welding method for the core tube and the brazing filler metal. On one hand, dosage of the brazing filler metal can be saved, on the other hand, the automatic degree is high and welding quality is high.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding device and method for solder, a core tube and solder. Background technique [0002] The core board designed by our factory includes the first panel, the second panel and several core tubes arranged between the first panel and the second panel. The core tube and the two panels are connected by brazing. The produced core board can be used in various fields such as building structures, vehicles, ships, aircraft, aerospace equipment, containers, bridges, roads, tunnels, rail foundations, furniture, culverts, vacuum tubes or bags. [0003] When the panel of the core plate is brazed to the core tube, there are mainly the following problems: (1) If the brazing material is directly laid on the core tube, when the panel is pressed on the core tube, due to the large area of ​​the panel, such as Using a 12m long panel, there will be airflow during the pressing and releasing proc...

Problems solved by technology

[0003] When the panel of the core plate is brazed to the core tube, there are mainly the following problems: (1) If the solder is directly laid on the core tube, when the panel is pressed on the core tube, due to the large area of ​​the panel, such as Using a 12m long panel, there will be airflow during the process of pressing and releasing, which will easily blow the brazing material, resulting in the inability to lay the brazing material neatly; (2) laying the brazing material directly will greatly waste raw materials and increase costs; (3) If If the brazing material is directly set on the core tube, the brazing material is also prone to shaking, which affects the brazing quality; (4) If the brazing material is set on the core tube manually, it will take time and effort, greatly reducing work efficiency, and increase labor cost
