Abstract
The present invention relates to a kind of metal tube pressure welding technique, for welding the metal tube that wall thickness is 0.5～0.8mm, including a pair metal tube of blanking, deburring, weld, examine overlap, remove removal of residue, go outer burr, the most qualified five steps of hunting leak with air pressure test.It is an advantage of the current invention that: pressure welding technique method of the present invention, owing to not using any welding auxiliary agent, decreases production process, decreases production cost；The main technologic parameters of welding sequence is determined by die size, and equipment is simple, therefore easily operated, welding quality stable, and production efficiency is high, low cost；Meanwhile, without solder flux, joint will not cause corrosion.
Description
Technical field
The invention belongs to welding procedure field, particularly to a kind of metal joint pressure welding technique.
Background technology
In order to meet different job requirements, it is often necessary to metal tube is welded, to increase its length, convenient use.
Traditional metal tube welding method is to use stored energy welding and friction welding (FW), by applying welding auxiliary agent, it is also possible to realize metal tube weldering
Connect, but these methods can be only done more than 1 millimeter metal tube welding；Wall thickness to be reduced will increase welding seam leakage probability, the party
Method cannot be applied in wall thickness only has the metal tube of 0.5～0.8mm to connect, and its complex manufacturing, production efficiency is low, raw
Product cost is high.
Summary of the invention
The technical problem to be solved in the present invention is to provide one can reduce production process, can weld wall thickness 0.5～
The metal tube of 0.8mm, production efficiency is high, after welding metal tube do not reveal, indeformable, service life length a kind of metal tube pressure
Welding procedure.
For solving above-mentioned technical problem, the technical scheme is that a kind of metal tube pressure welding technique, be used for welding
Wall thickness is the metal tube of 0.5～0.8mm, and its innovative point is that step is as follows:
(1) a pair metal tube of blanking, deburring；
(2) welding:
A. welding machine and upper/lower die are adjusted；
B. a pair metal tube being clamped in upper and lower mould respectively, the two-port of welding is stretched out outside clamp mould, and metal tube is to be welded
End is heated to 400～500 DEG C, then applies the upsetting force of 0.5～0.9MPa, makes the solder side of two metal tubes reach closely and connect
Touch, complete welding process；
(3) inspection overlap, removes removal of residue；
(4) outer burr is removed；
(5) the most qualified with air pressure test leak detection.
Further, described metal tube can be copper pipe, can be aluminum pipe.
It is an advantage of the current invention that: pressure welding technique method of the present invention, owing to not using any welding auxiliary agent, decreases life
Produce operation, decrease production cost；The main technologic parameters of welding sequence is determined by die size, and equipment is simple, therefore is prone to
Operation, welding quality stable, production efficiency is high, low cost；Meanwhile, without solder flux, joint will not cause corrosion.

(3) inspection overlap, removes removal of residue；
(4) outer burr is removed；
(5) the most qualified with air pressure test leak detection.
Embodiment 3
The present embodiment metal tube pressure welding technique, for welding the metal tube that wall thickness is 0.6mm, specifically comprises the following steps that
(1) a pair copper pipe of blanking, deburring；
(2) welding:
A. welding machine and upper/lower die are adjusted；
B. a pair copper pipe being clamped in upper and lower mould respectively, the two-port of welding is stretched out outside clamp mould, and copper pipe being treated, welding end adds
Heat, to 450 DEG C, then applies the upsetting force of 0.7MPa, makes the solder side of two copper pipes reach to be in close contact, completes welding process；
(3) inspection overlap, removes removal of residue；
(4) outer burr is removed；
(5) the most qualified with air pressure test leak detection.
Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments, above-described embodiment and explanation
The principle that the present invention is simply described described in book, without departing from the spirit and scope of the present invention, the present invention also has
Various changes and modifications, these changes and improvements both fall within scope of the claimed invention.Claimed scope
