Pipe is to weld jig, more particularly to a kind of anti-deformation weld jig.
Background technology
Concentration of local thermal source in welding process, it is very high to cause near heating sources temperature in welded piece, and away from heat
The relatively low uneven temperature field of the regional temperature in source, in the presence of this temperature field, the thermal expansion of Jin Feng areas metal is because by two
The constraint of the colder part in side is limited and produces elastoplasticity compression；In weld seam cooling procedure, weld seam Ji Jinfeng areas metal
There is elastoplasticity stretcher strain again because of the constraint by the colder part in both sides in thermal contraction.In the tension produced by cooling procedure
In, it is released more than the part of Materials Yield Limit, but still have the tension for being near or below yield strength to remain, and
The compression for balancing therewith is correspondingly produced in the region away from weld seam.So that being deformed during welding, welding quality has
Very big impact.
Welding fixture special is applied to multi-field now, and weld jig is due to being more targetedly widely used.Especially
It is in the environment of some bad environments, and such as environment such as electric power, chemical industry, artificial welding job is affected by environment easy to operate,
Planeness of workpiece is not high, the difficult control of welding quality.The Welder of workpiece higher-quality can be completed by welding special fixture
Make, weld seam is more uniform, firm, attractive in appearance, more efficiently, safely.
The content of the invention
It is an object of the present invention to overcome above-mentioned the deficiencies in the prior art, and then a kind of anti-deformation weld clip is provided
