Abstract
The invention relates to an Ultra Fuse welding process for a copper water tank. The process includes the steps that (1) a main plate and a radiating tube of the copper water tank are prepared; (2) the radiating tube and a part of the main plate are fused through automatic argon arc welding, and a joint made of copper alloy is formed after cooling; (3) traditional tin soldering is used for welding, and the local part which is not sealed is filled and sealed. The Ultra Fuse welding process has the advantages that the strength of fusion welding parts of base metal is high, deformation is not prone to occurring under the action of stress, and thus tin solder playing a sealing role can be well protected and is high in service life; the service life of the water tank manufactured according to the Ultra Fuse welding process can be more than eight times that of a water tank manufactured through tin soldering.
Description
Technical field
The present invention relates to a kind of copper water tank main leaf and radiating tube welding procedure, particularly relate to a kind of copper water tank Ultra Fuse welding procedure.
Background technology
Copper water tank main leaf welds with radiating tube, and the way usually adopted uses Sn-coupled SSBR.The gap between main leaf and radiating tube filled by the tin-lead solder of melting, forms the joint of sealing after cooling.Because the intensity of leypewter own is not high, the strength of joint therefore formed is not high yet.And the joint that tin-lead solder is formed is more responsive to the fit clearance between main leaf and radiating tube, and gap is larger, and bond strength is lower.Ultra Fuse welding procedure proposes to address this problem.
Summary of the invention
The present invention a kind ofly improves that welding portion intensity, water tank are not yielding, the copper water tank Ultra Fuse welding procedure of good sealing effect, long service life to overcome the above problems to provide.
Technical scheme of the present invention is: concrete operation step is as follows:
1) prepare copper water tank main leaf and and radiating tube;
2) by argonaut welding by radiating tube and main leaf local melting, mother metal forms the joint of copper alloy after mixing cooling after melting;
3), after argon arc welding completes, weld with traditional Sn-coupled SSBR, will local unencapsulated area filling sealing, and can the heat affected area of the reinforcement pipe that causes intensity to decline due to argon arc welding and main leaf.
Advantage of the present invention is: when water tank bears vibration or recirculated cooling water produces pressure pulse therein; the mother metal weld intensity that the joint that Ultra Fuse welding procedure is formed is formed due to circular arc weldering is high; not easily distortion is produced under the effect of stress; therefore can protect the tin solder sealed preferably, its life-span is high.And the strength of joint that traditional Sn-coupled SSBR is formed is low, under effect of stress, easy to crack causing leaks.At present, this technology is applied to copper water tank used on comings generating set by us.Do with pressure cycling test by making water tank by Ultra Fuse welding procedure and traditional Sn-coupled SSBR technique respectively, we find, the water tank that Ultra Fuse welding procedure makes can reach the water tank life-span more than 8 times that Sn-coupled SSBR makes.
Accompanying drawing explanation
Fig. 1 is welding route map of the present invention.
Fig. 2 is the joint that traditional Sn-coupled SSBR is formed.
Fig. 3 is the joint that present invention process is formed.
Detailed description of the invention
A kind of copper water tank Ultra Fuse welding procedure, concrete operation step is as follows:
1) prepare copper water tank main leaf and and radiating tube;
2) first by argonaut welding by radiating tube and copper water tank main leaf local melting, mother metal forms the joint of copper alloy after mixing cooling after melting, this strength of joint is very high, thus can solve the not high problem of Sn-coupled SSBR strength of joint, but copper alloy joint not exclusively seals;
3) after argon arc welding completes, then weld with traditional Sn-coupled SSBR.Like this, can not only by local unencapsulated area filling sealing, and can the heat affected area of the reinforcement pipe that causes intensity to decline due to argon arc welding and main leaf.
Claims (1)
