It sets.
Background technique
The bend pipe of petroleum industry and the small flange of pressure vessel industries etc. at present, in weld deposit process to its deformation and at
The features such as type is all unable to control, more demanding small along with the thin size of workpiece wall itself because of technique for overlaying, it is difficult to guarantee built-up welding matter
Amount and deformation.Meanwhile the workpiece such as large-scale pipeline, flange, valve body are at built-up welding inner wall channel, because the weight reasons of itself can not
It is welded on the positioner on rotary surfacing equipment, these heap weldments are easy to cause following problems in the welding process:
1, base material performance is poor, for welding high-carbon steel thin-walled base material, stainless steel base material or used petroleum valve
Body repair piece, surface generally permit no. water cooling, because water cooling will lead to Surface hardened layer or the structure property generation of such material
Variation, so that service performance is scrapped or reduced to base material.
2, poor flatness is shaped, during built-up welding thin-walled base material, temperature can increase over time, weld
The molten wide of liquid state molten pool can increase in journey, and when being overlapped between the road Dao Yu, forming can become difficult to control, and there is local layers
The problem of height, overlap etc. is uneven.
3, burn-through, after temperature increases, for sheet-metal duct when welding high temperature, base material can melt the problem of causing base material burn-through.
4, welding deformation, because of built-up welding long processing time, because of the thin reason of the high base material wall of temperature, the persistently heated meeting of base material ontology
Welding deformation occurs, makes built-up welding hole size by large effect, in addition can be equipped with and wait in interlayer if discontinuous welding
The cooling residence time welds again after temperature is suitable, and the non-uniform temperature difference repeatedly will also result in biggish deformation.
5, the reason of resurfacing welding material performance is poor, processes for a long time because of built-up welding, temperature can become very as time increases
It is high.The performance of resurfacing welding material declines, if the corrosion resistance of resistant material declines, wearability decline of wear-resistant material etc., mainly
It is to be embodied in dilution rate.Interlayer temperature can also be such that the service performance of base material declines, if the temper brittleness of base material ontology cracks, heat
Zone of influence hardness is low, and crack resistance is poor, and toughness is low, moulding difference etc..
6, welding efficiency low cost is high, and during test piece for welding, welding factor is more, but most factor is all weldering
Caused by connecing heat, therefore temperature, such as interlayer temperature are constantly controlled during built-up welding test plate (panel), temperature etc. between road, mistake herein
The Cheng Zhonghui occupancy most of the time goes cooling down workpiece, personnel equipment's higher cost.
