2, welding deformation, pipeline welding is Integral welded, and weld interval reaches 2-8 hours, and the temperature of pipeline is got over when welding Height, welding deformation are bigger.Temperature if do not cooled down during pipeline built-up welding, after pipeline entirety heap is soldered Degree can be very high, needs to consume the plenty of time for controlling interlayer temperature, etc. interlayer temperatures stablize after welding again.It is cooled at this Cheng Zhong, pipeline will receive non-uniform cooling, there is very big influence to welding deformation.In addition, when multi-layer welding, layer heap weldering Deformation after complete is bigger to bring difficulty to subsequent processing.

3, welding efficiency low cost is high, and during test piece for welding, influence factor is more, and most factor is all welding Caused by heat, therefore temperature, such as interlayer temperature are constantly controlled during built-up welding test plate (panel), temperature etc. between road, this process meeting The occupancy most of the time goes cooling down workpiece, and personnel equipment's cost can be higher.

4, sheet-metal duct built-up welding molding is difficult, does not machine generally inside pipeline, to the flatness requirement on welding fabrication surface Height generally requires 0.5mm.When high temperature continues built-up welding, the mobility of metal can improve as the temperature rises, resurfacing welding material Mobility influence postwelding molding, thereby result in the welding parameter of setting with the variation of temperature and become discomfort is used, cause to weld It is seamed into type variation, phenomena such as overlap occurs.

5, equipment damage, when for small-bore inner wall of the pipe built-up welding, the load of lasting heating Butt welding gun can be larger.It is main If the nonmetallic accessory inside welding gun can damage, lead to leak.
