Problems solved by technology

However, this exothermic welding device needs to use a metal bushing that matches the second welding material, which cannot be directly used in the existing welding bushing, and is cumbersome to manufacture and low in efficiency. Therefore, the structure of the exothermic welding device still needs further development. Improve

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0042] like Figure 1 to Figure 11 As shown, the device of this embodiment that can be used for welding pipes of various specifications includes a welding mold, which can be placed in the mold cavity 51 of the welding mold and flow into the molding cavity 52 in the welding mold in a hot molten state after being ignited One end can extend into the mold cavity 51 to contact with the solder, and the other end is located outside the mold for ignition strip 3 for ignition. The solder is a block body 4 of uniform specification, and stretches into the mold cavity 51 to contact with the solder. The end of the ignition strip 3 which is in contact with the welding agent is provided with an ignition box, and the ignition box is filled with ignition powder 12, and the end of the ignition strip 3 is inserted into the ignition box to contact with the igniti...

Abstract

The invention relates to a universal welding device for blocky welding blocks and an application method thereof. The universal welding device for the blocky welding blocks comprises a welding mold, a welding agent and an ignition strip, wherein the welding agent is formed by blocky bodies with the uniform specification; an ignition box is arranged at the end of the ignition strip and is filled with ignition powder; the end of the ignition strip is inserted into the ignition box so as to be in contact with the ignition powder; and the weight of the ignition powder is superimposed with the weight of N blocky bodies so as to meet the requirements of the total weight of the welding agent. The application method comprises the steps that the weight of the welding agent is selected according to the specification of a welding part, the blocky bodies are added into a mold cavity, the end, provided with the ignition box, of the ignition strip is arranged in the mold cavity, the ignition box makes contact with the blocky bodies, and the sum of the weight of the blocky bodies and the weight of the ignition powder in the ignition box is equal to the weight of the welding agent. The universal welding device for the blocky welding blocks and the application method thereof provided by the invention have the advantages that the welding device can be used in an existing welding mold, can be applied to connection machining of welding parts of different specifications, and is wide in application range and good in using effect.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding device for a general block welding block and an application method thereof. Background technique [0002] An existing invention patent application with the application number CN201380015814.6 titled "Ignition device for heat welding and its mold and heat welding equipment including the mold and device" discloses an ignition device for heat welding. The igniter comprises an electrically conductive metal bushing capable of encapsulating particles of a first solder material electrically connected to an inner wall of an inner chamber of the bushing, provided with an electrically insulating cover and a bottom substrate having an opening, when the second when an exothermic reaction has been initiated, the first solder material falls in a red-hot state through the opening towards the second solder material encapsulated in the solder mold; an electrode passing through the meta...
