This article compares the experiments which have been made with main parameters such as base metal, welding material, groove type, welding position, welding method, etc. under similar conditions and analyzes the influences of different heat-treatment processes on the properties of welding joint of SA213-T23. This article has some reference values to find out an appropriate and practical welding process that can meet the welding requirements of power construction and ensure welding quality.
The welding procedure of 40 mm thick 7A52 aluminum plate by using double wire gas shielded arc welding is tested to study affect the groove type and welding parameter to the joint quality. The best welding procedure parameters is confirmed for the double wire gas shielded arc welding.
The text introduce this kind of stainless steel-steel composite plate’s welding technical from welding material of stainless steel-steel compound plate,welding method,proper welding order,welding groove in many ways detailed.
This paper presents a thorough study of the effect of groove shapes X & V on the mechanical properties of the different matching welded joints, including impact toughness, hardness and tensile strength.
This paper describes the features of welding parameters, bevel type and mixed ga s arc welding of auto-matic welding machine,introduces the application of automatic welding technology in the lst and 2nd pipe-line section and analyzes the welding defects, defect category and measures to b e taken to ensure the welding quality.
By means of strictly controlling the welding process and manufacturing accuracy of the weldment,the proper joint bevel type,reasonable welding process have been well selected,which can make the product to meet the design requirements.
It is shown that the sensitivity of the echo-pulse method with the use of torsional waves to radial groove type imitation flaws is appreciably higher than that with the use of rod waves.
There is some evidence that the groove type is correlated with larger gland size; there is only a poor correlation with larger body size.
From the results, it is suggested that the combining site of SSL is a shallow groove type, recognizing the monosaccharide of GalNAc as the major binding site or Tn up to the Forssman pentasaccharide (Fp).
Calculation of the hermeticity of flanged connections with a tongue and groove type teflon seal under variable internal pressure
1.The influence of crack and groove type defedts on.
Gratings having arbitrary groove shapes are considered and explicit formulae are given for the leakage parameters of gratings with symmetric profiles.
Thrombus formation in the bearing was examined with in vitro thrombogenesis tests and was reduced by changing the groove shapes to increase the bearing-gap flow to 3% of the external flow.
Groove guides with various groove shapes, such as rectangular, triangular, parabolic, elliptic and cosine functions, are investigated systematically.
The "hot" dispersion equation is obtained by means of the self-consistent field theory, and the small signal analysis is carried out including the effects of the dielectric-rod parameters and the groove shapes.
The equilibrated grain boundary groove shapes for Succinonitrile (SCN) solid solution in equilibrium with the Succinonitrile (SCN)-D Camphor (DC) eutectic liquid were directly observed.
