weld metal

Studies involve examination of the parent material, the heat-affected zone, the weld metal, and the interfaces between all metals involved.

To simulate the effect of the defect on performance of steel structure, damage evolution law of weld metal must be predefined.

The test resultsshowedthat there was an optimum content of Ti, Nb, Co and Y-Mg in weld metal respective-ly.

Weld metal is composed mainly of acicular ferrite , granular bainite and a small amount of martensite.

The main influencing factors of the microstructure in weld metal are composition and cooling rate of the weld metal.

However, the propagating rate of weld metal will decrease with the increase in stress ratio under dead load and constant maximum loa. . .

The optimum prescription was finally determined by the property tests of the welding process and weld metal.

Welding consumables - Deposition of a weld metal pad for chemical analysis.

With the extension of welding time, heat input of friction welding surface will increase, thus the weld metal plastic deformation increases.

With the increasing of heat input, the width of columnar crystal is increased, the dimension of acicular ferrite of weld metal is increased.

Covered electrodes for manual metal arc welding - Procedure for the deposition of weld metal - Hardness tests.

The amount of the acicular ferrite and hardness of the weld metal increase as Cu content increasing.

Fracture mode is predominantly ductile in base metal. However, there exists intergranular fracture in the weld metal.

The additional silicon or magnesium pushes the solidifying weld metal below the cracking sensitivity level.

Fracture toughness of heat affected zone (HAZ) was between the base metal and weld metal.

Multiple passes are more expensive but usually deposit higher-quality weld metal.

Sometimes all that is left is a skeleton casting with weld metal.

Welding and allied processes - Determination of hydrogen content in ferritic steel arc weld metal.

The relation of the width of weld metal and parameters is also discussed with statistical equation offered.

The parameters that deeply effect on the bending strength were porosity, energy input and the overlapping of weld metal.

The microhardness of weld metal zone, HAZ and base metal decrease in totality after heat treatment.

The weld metal showed very good toughness at low temperature, and dominant microstructure of acicular ferrite.

Weld metal zone are mostly acicular ferrite which can improve the weld zone toughness.

The impact absorbed energy of weld metal is higher under lower weld porosity ratio.

With the increasing of heat input, the hardness of weld metal is increased.

The transition of fracture mode from base metal to weld metal may lead to dramatic decrease in fracture toughness.

The result shows that the resistance of the joint, especially of the weld metal in H2S saturated solution is very low.

Thetransverse weld specimen is used together with the base metal or all weld metal tension tests to evaluate joint efficiency.

The electrode has not only good usability but also low diffusible hydrogen, and the weld metal has matched strength and toughness.

The life and death technology was applied to simulate the weld metal filling process.
