They cause all the welding of double tubes, joint boxes and gas-collecting tubes to realize the backing weld of TAW-P. The quality of the double tube waste heat boilers have been improved.
An improved four-parameter DH model is used to deduce the double parallel-joint CMM measurement model. Error model of the double parallel-joint CMM is discussed based on the measurement model.
