It is well-known: since that there are mainly two types of is former for object residual stress caused by heating temperature is uneven in processing
Because: first be due to temperature it is unbalanced caused by local thermoplastic modification.Second is that volume expansion caused by phase transformation is uneven
Caused by local plastic deformation.And the residual stress as caused by scantling tolerance is often generated because of matching problem, example
As that must be drawn together butting steel plate when body section docking, these are drawn together by external broach and the structure that forms, outside
After power removal, there have been residual stress for whole system.The influence of residual stress is in most cases all played negative
Effect；It such as reduces component strength, reduces workpiece fatigue limit, generates stress corrosion and brittle fracture, due to residual stress
Relaxation, be deformed component, influence dimensional accuracy.
The method of traditional elimination residual stress, most practical is heat treating process, by means of be heat-treated facility, by workpiece by
Room temperature slowly, uniformly adds to 600 DEG C or so, and persistently keeps under this state of temperature 4~8 hours, slowly cools to again later
120 DEG C hereinafter, come out and cool down again to room temperature.
There is very big deficiency in currently used soldering opening stress elimination mode:
First: existing burner flame high concentration and temperature is higher is merely right for the characteristic that thermal stress is eliminated
Some soldering opening, which concentrates heating remelting that can not reach ideal effect or even component, to cause two due to cooling velocity speed
Secondary residual stress；
Second: limitation is larger, can not process the heavy parts of some fixations, and time span is big, and flexibility ratio is low；
Third: status both at home and abroad eliminates the mode taken substantially to the interface thermal stress of pipeline or steel plate at present, at heat
It is heavy to manage mechanical equipment, input cost is high, haves the defects that certain, not can guarantee welded complete while eliminating thermal stress
Whole property, reliability, safety and practicability；
4th: new residual stress can be generated after component assembly, prior heat treatment method is difficult to solve the problems, such as this.
5th: manual operation is high to the skill requirement of worker, manually adjusts the effect that heating temperature cannot be optimal, together
When manually-operated error and personal safety be also important consideration factor.
